I’ve heard great things about these and spotted one at the same Musicgoround I purchased the TSL head from. While staying over at a friend’s place in Atlanta one weekend, I went and picked this up. It has some really killer tones, and I’ve been playing it run into the FX return of my TSL head. Dialing in tones is a little tedious but they can be saved to any of 128 user presets, and can be recalled with a few taps of the front panel arrows or with a MIDI footswitch.
This is definitely more classic sounding than my TSL, and a lot darker. My only complaint is it is also noisier, especially at high gain settings.
(This is the earliest picture I can find of it)
