One afternoon (about 12yrs ago) I drove all the way to Morecambe (60miles) and traded in a perfectly good washburn KC90 for a new Les Paul copy. I thought I could get it home,set it up, drop in a couple of Seymour Duncs I had spare and then (and this was the realy clever part) sand of the headstock logo and refinish it with a design of my own.
Like an absolute fool I got home and started work on it straight away. By the end of the evening I'd dropped in the Duncs, set up the neck to a fantastic action/stability and sanded off the headstock logo. I had a rehearsal the next day so I thought I'd try it through my rig at the practice room. I can't tell you how cool I felt as I lifted it out of it's case. My band mates were in awe of my custum creation and so was I until I plugged it into my live rig and tried it at live volume.......
That f'kin thing screamed like a banshee, I couldn't understand it? I couldn't even get any kind of a guitar like sound out of it. I took the covers off the back too see if I'd messed up on the wiring, but no it seemed ok ??? My drummer started having fits of laughter and said "I bet it's made of plywood !!" I quickly scratched some of the black cavity paint off too check....and there it was in all of it's 18ply glory. I'd traded for the nicest playing, biggest piece of sh*t I've ever owned. I couldn't even take it back to the shop as I'd sanded the headstock DOH!!!!!!
The moral is...If you play something at realy low volume in the shop don't expect that when you take it home and drop some duncs into it, then put it through a Peavy 5150 at rehearsal that everything will work out just fine.
That was 12 years ago and I'm still stuck with that albertros of a guitar today !!!
Funny thing is I'm moving house this Wednesday and I actualy packed it this afternoon as 12 yrs later I'm determined to get some sort of use out of it....Maybe I should just bury it in the garden before I leave ????
