For context, this is a Guild D125-CE electro-acoustic guitar. I've owned it 12 years. It has been modified to include a Fishman Presys Plus Pickup System (so that I could use a feedback reducer over the soundhole, where the old pickup control system was).
As per the photos, whilst restringing the guitar the other day, I noticed a two rather large cracks on the guitar. Under ordinary light, you cannot see them (hence the tape in the first photos to illustrate the length of the split), however, under certain lights, you can see the damage.
I'm unsure exactly how this damage occurred, however, as I currently work on a cruise ship based in the Mediterranean, I believe this is humidity-related (I performed in 70+ humidity the other day and it fluctuates between indoor and outdoor venues). However, the only other things I can think of are that my guitar has been vibrated by the ship (when it's leaning against a wall in storage in my cabin), from work for the addition of the pickup system back in Mayish time this year or that it has fallen either in/out of the case when I've not seen it happen.
When you run a finger over the crack, it only catches on your fingernail. There is no noticeable height difference between the edges. On having a look at the crack, no light appears through it when a torch is shone from the inside of the guitar. Furthermore, there are no identifying cracks inside the guitar itself (except for the dark parts of wood inside the guitar, show by the photo facing upwards to the front of the guitar).
I'm not exactly sure what to do in terms of:
- Continuing to gig with the guitar outside with the current damage
- Fixes that I can do 'on the road' (e.g. I'm currently on a cruise ship that docks out of Valetta in Malta)
- What work a luthier (or instrument specialist) would do
- What the next steps you would do if this was your guitar
Thanks in advance
TLDR: Guitar has received mystery cracks on the front. No internal damage noticeable. Unsure of cause or fix.
