I unstalled my tonewood amp along with briidge mic i purchased from tonewood amp because i have a briggs that was feedbackj. What i am noticing is I cannot turn gain up more than 4 05 because fx begins to distort. Not sure why that is
Which pickup are you using? If it's the NG-1, you'll want to follow the instructions here to reduce Master Gain and to set the Notch Filters. It'll take care of the feedback issues!
