    I use this as a seperate head- I bought it as a head only, in a Fender Bassman headcase. Super amp & LOVELY crunchy overdrive tones. REALLY versatile with the Active EQ, but I mostly use the standard (PASSIVE) Bassman type EQ & just use the active to boost/cut a problem freq in a room.

    To put in a head case, you need the dimensions of a twin reverb chassis.
    Tubetown has some, mojotone, tube amp doctor, … to name a few.
