Removed Champ feedback loop - Sweeeeeeet!

Sidney Vicious · February 11th, 2004, 01:04 AM

After searching this and other forums I took the plunge and clipped the feedback loop on my '66 BF Champ tonight. I am very happy with the result. The amp seems to break up somewhat earlier in a loose and very open and toneful way. At the volume I play (strictly at home for the amusement of me and the babies and even my wife - I think!) the mod was a big improvement to my ears. Thanks again for all that free advice!

Remove chassis and look inside. You should see three wires connected to the speaker jack. Two of those wires lead to a transformer. The third connects to a resister on the circuit board - clip that wire. Operation complete.

REMEMBER THAT YOUR AMP EVEN UNPLUGGED MAY CONTAIN DEADLY VOLTAGES SO USE CAUTION.
