Well, they are $200, so I doubt I would ever be tempted - but lots of OD pedals cost $200 nowadays, so there must be a market and it's not me. I think that if tube pedals were truly better, they would have taken a bigger market share the first two or three times they came around. I also can't really comprehend the "two footswitch buttons in a fairly standard sized housing" approach. I made the mistake of buying a couple of those little Keeley mini-mfx. Just useless for playing live. Maybe there are a lot guitarists around with really tiny feet, eagle eyes and the coordination of a ballet dancer?
