Hi all,
I purchased a Warwick Corvette 5 string from another member on here. it had been modded with a John East 3 band premp (3 stacked knob affair).
There is something wrong with the treble circuit - the boost/cut treble is intermittent. The pull bright switch works fine and the bass works fine. Just the treble knob.
I've inspected all the connections and made sure they are correct - they appear to be.
John East have not got back to me about buying a replacement bass/treble module - not great customer service! I have cash I'm willing to give them and......nothing.
Any one got any ideas what might be wrong? Otherwise I'm going to have to put another pre amp in.
