I have seen a lot of good word/vid on the Tre-verb. Found one for $180....might hit it. But I have a guitar I need.
The one review that criticized, and PTM's review supports is that the range knobs go from little to Uber-verb too quickly. But - as that review pointed out, if you are a Surf Guitar player - which is who this might be targeted at, you are fine with that.
I'll need to play one to see about that "Amp reverb on 3" all the time sound. For that "just a touch" of reverb.
