I would guess uses. I read an interview with Tipton where he talked about using the smaller solid state Marhalls in the studio. A couple of people here called bull**** on it. Then another member found a video of Glen in the studio and low and behold he was using a MG30. This was three or four albums back.
Ahh...gotcha. I would imagine Sneap not going that route or Faulkner for that matter. On the flip side, if it works it works. Studio land is often way different than live.
