Hey guys!

I have a 550b EQ here that has no effect in the top end last 2 boost positions - so the +9 and the +12 positions do nothing. Does anyone know what might cause something like this?

Any advice much appreciated!
Thanks,
Sig
 
Sounds like the switching contract not making connection. Could be the switch itself or poor solder joint on the switch or adjoining parts.
