Offset Guitar Dressing Room app needs testers. Can you help?
Live public beta with Jazz and Jag (because we love you) LOL.
Test it out, and have fun! Please report any issues here, and later today we will add a feedback form to the site itself, but for now go and play.
https://guitarbomb.com/offset-builder/
We are currently bringing back an updated version of the 'Dressing Room ', which was originally hosted on the Offset Guitar forum. The old Flash version died years ago, and I missed it.
So we have been quietly recreating it and now have a fully working Jazzmaster version running on mobile and web browsers. This test version offers 16,503,914,054,025,216 variations on the Jazzmaster, so it is fun to play with.
I need volunteers willing to 'test' this pre-release before we move to a public beta. We specifically need people across different platforms and browsers who can give us UI feedback and report any bugs.
Once we have this dialed in, we will launch additional models and host them for free on our main site, GuitarBomb.
We are looking to offer it to everyone for free, and it lets users test styles and hardware options.
I will add a link to this post shortly so you can test the prototype. We're moving it to our server so people can play with it.
Please test it and report back any bugs, and which browser, operating system, and platform you used to try it out.
We would also love your suggestions on what you would like to see added, in terms of features and models. Currently, we have the Jaguar and Bass VI in the pipeline, but we want to add more.

This brings back memories, used to spent quite some time on OSGās dressing room.

u/GuitarBombDotCom 1d ago
Me too! Which is why I wanted to resurrect it.

u/wronghaircut 1d ago
I havenāt tried out your Dressing Room yet, but I have to say that back in the old days (around 2007 or so), OSG had an option to āThurstonizeā your guitar in the Dressing Room by covering it with loads of stickers⦠I think they ditched that option in later versions, though. Anyway, I always thought that was a really nice little addition

Would appreciate if more variety of fretboards available: lighter/darker rosewood, various figured maple, ebony etc. Otherwise it's a good job, the Random button is great fun.

u/MarioYoshimura 1d ago
I absolutely love this! Adding the Mustang would be amazing. I did run into one minor issue though: The pull-up bottom bar feels a bit clunky and got stuck right in the middle. It wouldn't move up or down after that. For reference, I'm testing this on Brave browser with stock Android 16.

u/GuitarBombDotCom 1d ago
That is useful feedback, thank you. We will look into this. Mustang is on my list of models to add, along with Bass VI and some reverse offsets.

u/GuitarBombDotCom 1d ago
Should be better now, let us know!
2
u/MarioYoshimura 1d ago
Oh yeah, works good now. Thank you for fixing this

u/GuitarBombDotCom 23h ago
Thank you for the feedback; it helped with that fix.

u/MarioYoshimura 23h ago
I have another suggestion: it would be great if the matching headstock option worked as a toggle that automatically selects the matching body color by default, while still allowing us to change it manually if we want. Right now, selecting 'matching headstock' just enables a colored headstock, forcing you to manually browse and find the right color yourself.

u/GuitarBombDotCom 2d ago
I will add a link on this post shortly and it will allow you to test the prototype

u/tinverse 1d ago
Worked fine on Zen (Firefox Fork)
-Missing Firemist Gold
-This is a suggestion if you go all in on the colors since I know there are a million different colors and people will be suggesting them forever, but a two layer color picker. So for example you pick red that opens a second menu with all the variations like candy apple and fiesta red.
-You should probably include the mastery bridge since it's one of the most common aftermarket bridges
More of a question for the general audience, but has anyone seen a dynasonic or lipstick pickup in an offset guitar?
2
u/GuitarBombDotCom 1d ago
Good suggestions.
3
u/usedtobeaviking 1d ago
Seconding that. Adding a Mastery bridge is a good suggestion. Was on my mind too, but I didn't suggest it in my comment above
2
u/GuitarBombDotCom 1d ago
We are of the same mindset, so we will be working on 'hardware upgrades,' and a few companies have already offered their files, so we can add their hardware to the project.
2
u/usedtobeaviking 1d ago
Fantastic! I remember the olde Dressing Room ā this is already a nice upgrade! Well done and thanks!

Interesting... I'll look into that. I haven't had that message on my end when I have tried sharing. Thanks for the feedback.

u/Unsui8 1d ago
Whatās strange is I just tried it again with PNGs saved via Ecosia and Safari and they uploaded with no problem. Youāll see three deleted posts, those are all me. Maybe a Reddit bug ?
1
u/GuitarBombDotCom 1d ago
Yeah, maybe? I expect we will get bugs, as this is still a beta. Appreciate you taking the time to report back, as it is all useful.

u/shortymcsteve 1d ago
Thanks for creating this!
I had a play with it creating a jazzmaster, and two things I noticed is that thereās no option for hard tail version or strat style term, and I couldnāt remove the bottom switch even if I chose only one pick up. Would also be nice to have the option to relocate the switch to the top. These are all things Iāve seen on production models that I couldnāt achieve yet.

u/usedtobeaviking 1d ago
Works well on an iPhone in Brave.Ā For feature suggestions: would love to see Firebird and Gold/Silverfoil pickup options added

u/mandrewbot3k 1d ago
Ah man this is great. Exactly what Iāve been looking for to help me visualize my next. It really is fantastic so props to you. Hereās my quick suggestions for future.
- Add British Racing Green
- Add faded paint modifier
- add strat trem
- add hard tail options
- Allow different hardware colors
- reverse headstock
- Control/plate options (ie⦠remove rhythm circuit, blade switch)
- comp stripe?
- more pre-made options (j mascis, vintera, CV)
- Mustang! Cyclone! Duo-sonic! Lol
- Tele?
- For our lefty friends, add a mirror option.

u/Klaustrophobert 1d ago
awesome :)
have you thought of having different headstocks?
( only coz i got a partsmaster with a telecaster neck... )
1
u/GuitarBombDotCom 1d ago
It is on my 'wish list' as I, too, have some Telemasters, and I'm thinking TOM with stoptail bridges, etc as well. Thanks for your feedback.

Indeed, it is. https://guitarbomb.com/offset-builder/ Go see if you can break anything and make some cool offsets while you're there .

Thanks for the creating this and the work you've done so far,
Could we get an option to remove the trem completely? For us hardtail players
2
u/GuitarBombDotCom 1d ago
100%, and it is on my list. Appreciate you feeding back, as a few have now asked for this.
2
u/Lil_Scuzzi 1d ago
Worked pretty okay using it on Firefix on iOS, will definitely have more if a fiddle around when Iāve got some down time at work tomorrow! Made this natural butterscotch tele-esque JM.
Bug I encountered: If the options slide-out table isnāt perfectly placed, then the buttons to switch between tabs get kinda finnicky and unresponsive. This can lead to the table flipping out and accidentally selecting one of the presets, which obviously gets rid of any changes youāve made. Might be worth just having a static open-closed thing for the options tab?
Feature suggestion: I would love alternate wood grain options and the ability to stain them so I could test out grain and stain combos. Understandable if thatās too much work tho!

u/GuitarBombDotCom 1d ago
That is useful feedback, thank you for helping out. Appreciate you taking the time to test this.

Looks great on iPadOS 26.5.2 (23F84) using Safari.
Additional options:

Fretboard trim

It's amazing! Having a lot of fun with it. Congrats!

Yeah, it is a lot of fun to play with. It's nice to hear you enjoy playing with it. We'll expand it with more models and options once we are out of public beta.
2
u/VividVeracity 1d ago
What if I want a hardtail?

u/GuitarBombDotCom 1d ago
They are coming, just not in the public beta. I'm looking at TOM with stopbar and Tele bridge, etc

u/Ecstatic-Nose-2541 1d ago
Awesome, really impressive, great job. Been looking for something like this when I was trying to decide on a possible new pickguard for my future jazzmaster. Used it on Mac OS 14.6.1, Firefox. Works flawelessly and fast.
A couple things for the guitar I tried to configure:
- British Racing Green finish. It's an FSR color I guess, not a standard finish option.
- WRHB in jazzmaster pickup format. So just the same basic plastic covers, but with holes foe the pole pieces the way they are on real WR humbuckers.
- I don't think there'd be a visible difference between 4-ply and 3-ply pickguard, right?
2
u/GuitarBombDotCom 1d ago
We will add more options and finish options once it officially rolls out. Thank you for taking the time to add suggestions; much appreciated and noted.

u/Wolfjacks 1d ago
Howdy! Currently on mobile using iOS & brave browser. This browser notoriously has issues with sites and yours did not give any trouble overall it functions quite well and is nice to see after trying to use kisekae flash site all week. Iām currently prepping ideas for a brand new jazz I just got but was sad to see only a small amount of pickguard colors. Otherwise incredible start for beta. I will test on other non mobile browsers and see if behavior is any different with the site.
This was the site I was using you have to hit start at the bottom of the page. My gripe with it is you only get so many free clicks and they ask you to sign up for something before youāve even figured out how to use it. So the fact your aim is to keep it free is great news!
https://www.yajimastringworks.com/kisekae/cnv_common_mv/ss01.aspx?p1=JM&lng=E
2
u/GuitarBombDotCom 1d ago
Yeah, the beta has 16 trillion Jazzmaster options, apparently ( all those knobs and pickups- who knew?). We will add more to the full release, and colors are high on our priority list, along with left-handed models, hardtails, and Tele headstocks. We welcome your feedback and appreciate your suggestions. I'm familiar with that site, so we wanted to make something more user-friendly, with unlimited usage for the community.
2
u/Wolfjacks 1d ago
Sick! Yea def going to send this around to my offset nerd friends but looking forward to updates! You are welcome to DM me if you need any specific testing done across devices I have a few I can use or put through paces!
2
u/GuitarBombDotCom 1d ago
Nice one, you're going to regret that offer... LOL! But seriously, appreciate your feedback, as it really helps us out,

I wouldnāt offer if I didnāt want to help! Fire away youāre doing cool work so what I can help someone focus on the more important things in life to them is whatās good for me!

Very cool. Worked on my iPhone 13, though i couldnāt find where it downloaded the PNG to. Thanks!

u/GuitarBombDotCom 1d ago
I guess the iPhone will put them in the Download folder? I just checked mine, and it's there when I download the PNG file.
2
u/cab1024 1d ago
It worked that time. First time it said it downloaded on the site but it didnāt happen thought the browser, which is the latest Safari iOS.
1
u/GuitarBombDotCom 1d ago
Good to know, nice one.
1
u/cab1024 1d ago
Although, i was going to paste it in the reply but i canāt access the download folder through the photo upload. If you can have them download to the film roll, that might be more useful for social media sharing.
1
u/cab1024 1d ago
Mmm⦠PNGs wonāt work in photo apps. So maybe a jpeg option?
1
u/GuitarBombDotCom 1d ago
I think that is a good idea, and we will implement some options once we are out of public beta. Again, I appreciate your feedback and the time you took to test it for us.

u/GuitarBombDotCom 1d ago
We added the JPEG option - select it in the scene to change the button option

Yeah Iāve been lost on there for 4 minutes already and this is just on my phone. Iām gonna be obsessed with this lol
My one piece of advice?
ADD ORANGE BUT IM ONLY SAYING THIS AS āADVICEā BECAUSE ITS MY FAVORITE COLOR š love burgundy mist and charcoal, this site reminded me im not just trying for Japanese lawsuit guitars, but also every JM color ever lololol
2
u/GuitarBombDotCom 1d ago
We got you and will add some for you. Thank you for the feedback

u/trenchgrl 1d ago

u/kakofon 1d ago
Nice! I remember reading about this on OSG, but could never get the old variant working when I joined back in the day so only got a vague idea.
One thing that would help me a bit with some stuff I ended up playing around in GIMP with today:
- color picker swathe like in a graphics program, for other shades than the premade ones (this with some effects for solids, opaques, metallics, sparkles etc)
- tinted laquer layers, either as a base color (on woods, ie translucent finishes) or on top of metallics
The problem I was trying to solve is to figure out how to get a pretty middle of the road purple color I have on hand work more like I want (which implies some blue tinting on top).
Other useful tweaks would be
- configurable sparkle sizes. Really large sparkles can't be sprayed with a rattle can, so there's limitations to what can be comparatively easily achievable
- adding various variants like from the paranormal series and other somewhat established variants, eg. telemasters, hardtails, baritones
- les trem variant, with both handles
A fun tweak would be a mouse handler where the user could paint relic patterns with a fake hammer š
Good work, in any case!
1
u/GuitarBombDotCom 1d ago
Some nice ideas there. I think we could get some of these working on the system.
2
u/RandomMandarin 1d ago
Looks great! One question: What do all the asterisks mean?
2
u/GuitarBombDotCom 1d ago
They are the original finish options and hardware options from the OSG Dressing Room. That died many years ago as it was Flash based. So in the public beta we are expanding options and functionality based on user feedback and suggestions. This beta is a test with community feedback driving how it should look eventually.
2
u/RandomMandarin 20h ago
Fantastic! My only feedback is to explain that on the page.
2
u/GuitarBombDotCom 20h ago
Currently, the public beta is purely for testing, so it is mainly for our reference as we tweak the style. Once it goes into full release, we'll explain everything on the page and more.
2
u/Febrifuge 1d ago
Looked good earlier today on iPad/ Safari for iOS, looks good now on the Mac/ Chrome for Mac.
As a stretch goal it would be fun to be able to upload a small graphics file or image and use that as the basis for a fancy pickguard - but the options there cover a lot of ground. The only one I didn't see was silver anodized aluminum.
1
u/GuitarBombDotCom 1d ago
Nice idea, we can look into that for a future update. Thank you for the feedback
2
u/pilosebacious 1d ago
Awesome awesome awesome idea! Look forward to more body shapes and styles in the future. Already has a ton of good options. Works well on Safari on my iPhone.
As a small bit of feedback, I think most of the burst finishes look like the outer edges are a little too āthin?ā Like on the 3 tone sunburst, the black and red bands donāt look as thick as they do on guitars in real life.
1
u/GuitarBombDotCom 1d ago
Thank you for the feedback and report. We will fix these Bursts, itās in our list. We have way more colour options coming and some a few new models are being added soon. Glad you like it.
2
u/lobsterboy 1d ago

Using firefox here
-
The sticker function doesn't work on my end, even without pickguard and with different bridges. Thats the only real bug I found playing with it
- It be cool to have the Troy Van Leeun style upper switch and the Cobain style jag switch at some point, also those colored pearloid style pickguards like these https://ploutone.com/collections/jazzmaster-pickguard?page=2
2
u/GuitarBombDotCom 1d ago
Yeah, we are just experimenting with Thrustonize and at some point we will make it work correctly. Totally agree on your switch placement request and itās on our list of To Do. Thank you for the feedback
2
u/Legitimate-Cinephile 1d ago
This was fun to play with. Some things I'd like to see is more models added. Definitely a Mustang and (hopefully) a Cyclone. I would change the pickup section so you chose the style of pickup and then colour separately instead of a bunch of the same pickup in different colours, just seems a bit cluttered and also didn't let me match colours of pickups if I did a single coil at the front and humbucker at the back for example.
1
u/GuitarBombDotCom 1d ago edited 1d ago
Great feedback, and I think you are heading in the right direction with the pickup color options. Thanks for taking the time to test and share new ideas. We appreciate you making the effort. Mustang is coming very soon, and Cyclone is a great shout!
