FYI I sold it a few months ago, even if I liked it a lot, it didn't correspond to my priorities any longer.
After 2 years of using it, here's what I think
THE GOOD
- It's the only tube pedal I know which enables you to have "2.5" channels at your footstep:
- Green channel: always on tubbey clean tone, with its proper EQ
- Blue channel: overdrive (second EQ, shared with the Red channel)
- Red channel: distortion (EQ shared with the Blue channel)
- Tube swapping is easy and fun
Before I sold it, I have used it a lot for gigs, and it was great to switch easily between a clean tone, just a little grit, and more pronounced distortion. It was great.
THE BAD
- The "tube warmth" in the green channel is subtle, hardly noticeable in a band mix. I think what I liked in the green channel is more a consequence of the scooped EQ than the added tube warmth (when EQ knobs are at noon, it corresponds to a boost in bass and treble and a cut on the mids)
- The EQ center points are designed for 6 strings guitars. It's OK to compensate for the loss of bass on the Blue and Red channels, but it's not the best EQ for bass guitars if you need to do specific things.
I think that a few Sushibox pedals will allow you to alternate between an always on clean tube tone and a boost channel, including the new Venus X, so you'll get only one level of drive instead of 2, but the EQ section will be much better optimmized for a bass guitar.
