ahpook Posted August 12, 2009 Share Posted August 12, 2009 right - here's the score. played the wettest gig i ever a few weeks ago in wales, and all my equipment survived, except for my boss bass chorus - it no longer works properly when powered by a wall wart (sound is distorted and very quiet). now, i'd like to get the back off to check it's not something easy to fix, but one of the screws on the bassplate is frozen in - i've tried WD40, heating the head of the screw up with a soldering iron, but still no luck...and the screw's getting pretty stripped now. any good ideas before i give up and drill the offending screw out ?

crez5150 Posted August 12, 2009 Share Posted August 12, 2009 One thing you should try if you haven't already is to try and tighten it further...... sounds mad but works... should help losen it up Quote Link to comment Share on other sites More sharing options...

ahpook Posted August 14, 2009 Author Share Posted August 14, 2009 well i tried mrcrow's suggestion, but only succeeded in knocking a corner off the offending screw. now what ? drill it out or just snap the bassplate off ? i'm thinking it might be a better option to just buy a new pedal - there's no guarantee that i can get it working properly anyway.

ahpook Posted August 15, 2009 Author Share Posted August 15, 2009 well, i've given up and drilled the head of the screw out. sadly i can't see anything obviously wrong with the pcb - no scorches or obvious mess. gonna leave it open in the vain hope that it dries out during the day, and then have a proper look tonight after some work on the bathroom. hope i can resurrect it...
