Amp Clean Combo
This models the clean channel of a amp that went on sale in 1975 and con-
tained two 12” speakers. As the name suggests, it produces a clean tone with
a tight sounding character, and a deep and compact low-end. When pushed
hard the bass tends to crumble. The original amp doesn’t have a Presence
control but does have a Bright Switch. The Presence control on your Pa4X
emulates this switch when Off and On, plus all points in-between.
