Is there a tone control defeat switch (sometimes called

see if the tone function is restored. You should also try
turning the affected control back and forth several
times.

Is this switch usually on the inside of the device? I'm
looking for it,
but I can't find anything like that...its just a tone
control bypass
switch? I don't think this unit has one...

I tried dialing the treble pot back and forth, but it does
nothing...this problem is consistent and there is no
scratchy sound or
cutting in and out

thanks


If this unit has such a switch, it would be on the front
panel. It looks like you need at least an ohmmeter to see if
the pot if working correctly. If it is working properly by
comparing readings from both channels, then post back.
