Inputs and controls
•
two guitar input jacks, normal (A) and low gain (B)
use the normal input for most guitars, use the low gain input for very high output guitars
or other signal sources. Both inputs can be used at the same time, in which case they
automatically switch to normal gain. Useful if you use two guitars on stage, or for
teaching etc.
•
gain
adjust to taste, at higher gains the harmonic setting will have more effect, in a similar
way to a valve preamp. As a starting point set to 12 O'clock.
On the harmonic setting it is
possible to overdrive the preamp slightly with high gain settings when playing loud
, This is deliberate, but if you
want a cleaner sound, turn the gain down, or use the clean setting.

deep setting is similar to normal, but has slightly more bass and less treble
bright has a deep mid-scoop and some treble boost, similar to a Fender AB763
