[HAM] Subject: B3 question:

Try manipulating the "tone control" pot on the chassis of the AO-28 
pre-amplifier (from the back of the organ).  Its a cheap place to start. The 
other pot controls the percussion decay time, and you might like a little 
slower decay if your percussion is weak.  Flashing the percussion switches 
might temporarily put some zing back in the keys.   New tubes and a pre-amp 
rebuild should precede any thoughts about recapping the TWG.
