Having picked up a old dynaco SCA-35 amp, I noticed it
has a loudness
switch. This boosts base and treble with your volume levels. The catch is
it requires a special 4 lead pot that nobody seems to make nowdays.
This may keep most bass at a resonable level if you impliment a loudness
control. Since I live in a apartment I can't have earth shaking bass, so I
am not worried about it.
Loudness boosts bass and treble at lower volume levels (ie flat when loud),
the idea is to match the sensitivity of the ear, but in practice it is just
one more distortion button for salesdroids to push that should be unpushed.
Most likely it is just a ganged pot, look harder, or at a hamfest. Better
skip it.
