Hi

I am new to this group and to the Bit 01.  I bought one yesterday from a person on Craigslist 
and it has a weird problem, not a "bad jack" as he stated.

It doesn't sound like it has a dead voice.  Instead it sounds like a capacitor somewhere is bad 
-- if I hold down many keys, it sounds fine, but if i just press one, it sounds weak.  Here's a 
recording of it:

I just saw the other bit one problem thread, but this seems different.  Can anyone suggest a 
fix for this issue?

Many thanks in advance,
Justin
