The
SEM allows the tone of a single-ended amp to
be produced by any push-pull fixed-bias or cathode-biased
amp. It also allows for any blend of those sounds
with a continuously variable control. The SEM
also is often described as "poor man's Power
Scaling", as it offers a significant power
reduction and early overdrive of the amp. This has
been a feature of London Power's own amps for
many years, and players call it "the tone control
I've been looking for on every amp I ever owned".
For
players considering "black-facing" their
Fender amp, the SEM offers dialable black-face
sound without sacrificing silver-face stability.
The
installer of this mod should be able to recognize the
relevant circuit points without a layout or schematic
for the subject amp.
