Summary
Congratulations on acquiring one of MI-Audio’s hand made pre-amps. Essentially this pre-amp has three
separate channels each voiced to match classic amplifiers that are no longer in production, which are…
Channel 1 – American Clean
Channel 2 – UK Crunch like older JCM800’s
Channel 3 – US Heavy Rock like older Soldano amplifiers
Each channel has options for standard or “boost” control, there are 2 master volume controls and setting
as well as dedicated FX loop which can all be controlled by a supplied 6 button footswitch.
