I played this sick combo amp in a recording studio - I saw "Peavey" on the plate and thought terrible things.. I was wrong. Hybrid, solid state and tubes, together or separately engaged. White face plate .. T-400 or something? Did a lot of searching online and came up with nothing. Smoked every Trace, Mesa, or Ampeg I've ever played. Blasphemy? Perhaps, but true. What was this beast? Cab was maybe 1x15 or 18?
