Hi Richard!

OK - the bypass caps might cause high-frequency loss though if they are
too big.  The guitar circuitry is high-impedance and therefore much more
susceptible to such things...  You might also want to visit a ham radio
or general communications store if there is one in your area. There are
things called Ferrite Beads which can be applied to wires to choke off
any RF coming through them.

RW>Some good thoughts.  See  what we can do by getting him to replace those

Check it out - it could be a bad solder joint in the cable or the jack
and you don't want to spend the time tearing thing apart before you
know exactly where the problem lies.
TTYL - Dave
