Title: Help with Ceriatone Liverpool problem. Post by: boogieguy on February 09, 2010, 08:20:23 AM I have a problem with what sounds like feedback when the Master Volume is moved past "4". The amp sounds awesome and works great up to that point. It sounds like a low mid howl even without anything in the input.
The master volume is the 1 meg pot wired from the layout on the half power mod on the Ceriatone website. Any ideas would be appreciated. Title: Re: Help with Ceriatone Liverpool problem. Post by: cmoore on February 09, 2010, 11:32:57 AM Did you add the MV? Just a guess, but it sounds like either a lead dress problem, or maybe you need to play with the Presence. Does the Presence affect it at all? Maybe adjust the neg feedback to that circuit via the 100k or the cap on the P Pot. I really don't know, but those are a couple things to try. You may need to get some help from The Garage.
Good Luck |
