- The FuzzBuster
With most new amps, using an attenuator violates the warranty. For a good reason, too, as attenuators often cause catastrophic component failures. And quite often, newer output transformers don't offer the smooth tone of their vintage counterparts.
With vintage amps, the output transformers are irreplaceable.
The FuzzBuster prevents damage caused by attenuators, dummy loads, power scaling and variacs. It also removes any possibility of fuzz/fizz caused by these components, as well as by bad output transformers.
When installed in vintage amps, the FuzzBuster protects the irreplaceable output transformer with minimal impact that is easy to remove.
You, or your tech, simply solder(s) two FuzzBuster wires to two power tube sockets. With the FuzzBuster installed, your amp is protected and will sound smoother when pushed into power amp distortion.
