Wall tone ... I sold my amp at the cottage yesterday, before going back home. I still have 5 days here with an electric guitar without an amp. Since it sounds somewhat dry, I tried to find sounding boards through the house. I started by sticking the body of my PRS on the table ... not bad. I then toured the entire floor to find the best tone I could. The bee's knees was from having the back edge of the body to the door frame of the pantry with louver doors that give me a bit of ... reverb ! That's where the P90s shine their best woody tone I'll probably come back home with a wall worn PRS . You ever tried your appartment/house for its native tone ?
