No, the thought of fettling the body fills me with dread 😂
The pots are full size CTS pots courtesy of KiOgon so that does limit the available adjustment. However, the control plate did come with a cheap wiring loom that has mini pots and even though there was more play with the position it still doesn’t look right.
I think I need to stick to a more traditional P-Bass pickguard shape and I did wonder about using a ‘Phil Lynott’ style mirrored plate and cutting that down. It would be made from acrylic so not quite the real deal but it might work. I came across this bass on Reverb which gives some idea, although the red tort in this example doesn’t look good IMHO.
