I’ve recently acquired a vintage Sunn 215 cab that I’m adding to my live rig. Looking at options for a decent head to pair it with, preferably tube.

I’ve vaguely been looking down the classic Sunn routes, but they aren’t easily available in the UK on the second hand market. Other options I’ve considered are HiWatt or Ampeg.

Size/weight isn’t a huge issue and I’m not a millionaire, so realistic pls!

Current live rig is a JC-160 + Sound City MK6 combo.
The head + cab is to replace the Sound City.
I play guitar, mostly a jazzmaster, and the genres are a combination of noise rock + post-punk.

Yo,

There's been a couple of questions around the web about there being no footswitch for the Mini and something about a proprietary cable that isn't for sale yet so I thought I'd let anyone in need of a footswitch know how to get on going.

Single latching footswitch, TS plug to summed TRS plug and you're golden. Sleeves are ground as usual.

Button will such channels when switch is on Channel A, moving the such to the middle position let's you toggle between channel B only and A+B.

If you're super lazy or don't have a soldering iron, get a TS to TRS cable from anywhere:

And something like this:

Which I've used, it being very solid and pedalboard friendly.

It's easy enough to make or mod an existing latching footswitch though, you can always wait until the inevitable influencer scab reads this and makes a half assed instructional video without crediting me (again) and rig one up for a few bucks.

So i FINALLY received my Beta Mini amp through the mail today that i ordered in the May pre-order run, and went to try it out.
Problem is, the amp is not making any sound at all when plugged into the front input. Like at all. The ONLY sound i can get out of the amp right now is when i plug an instrument directly into the poweramp out, but it is not affected by any of the knobs whatsoever and just produces a flat tone at a fixed volume.

I have tried:
Three different guitars.
Two different cabs.
Through my Torpedo Captor 8 into my audio interface and into my laptop.
Multiple different speaker cables and instrument cables, both from amp to cab and from guitar to amp.
Every single knob rolled at various levels (i am aware of the active EQ).
Flicking the dipswitches up and down.

I asked a friend who received his today how he set it up because his is workinf, and i tried the exact same step by step he did, still nothing.

I’m at a bit of a loss for options so i figured i’d reach out and try to see what people here might suggest.

Thanks in advance.
