Yep, *four* three way switches.
1) tight switch
2) gain switch - goes from a distinctive clean to blues to rock to metal
3) voicing switch a - adds a low mid to the EQ and changes the response
4) voicing switch b - adds a upper mid to the EQ and changes response
Trying to do some clips, VERY versatile module. Did this to see if it could be done and also because I sometimes rehearse with one of my bands - using a Randall RM20. I like this because I can spin a few knobs and go from ZZ Top to metal to a versatile clean that has compression and a tiny bit of grit to crystal clean depending on pickup strength.
Crazy, eh?
