There´s all sorts of reasons why people butcher their instruments. No wonder, who better to turn to when you´re about to turn crazy
than your guitar? There is no better friend than an old gibson bass, and being a bit messed up might turn your personalized axe into something quite different too - it´s become your therapist , doctor or whatever. That´s no bad medicine at all
When I grew up, there was this puzzled old man who claimed to know a hundred different A7 voicings. I never recall seeing him
with a guitar or met someone who heard him play. But one day his fender twin reverb came in for repair in the local guitar store,
and it was painted with dots of different colours all over... And of course, it wasn´t a cosmetic modification.
He said that they coloured the tone of the amp just the way he liked it.
