They're OK, but they're kind of overrated in my opinion. They get a lot of hype from the petulant Seymour Duncan commune. I've gone through a few of their pedals and pretty much have tried them all, but nothing they make necessarily stands out to me as spectacular. The owner is a prick though. The last pedal I bought of their was a DLS, and I kind of liked the tone, but it had kind of a real dry, firm, rubbery feel that only became more pliable when the gain was maxed, so I called him thinking there might have been something with that pedal. However, he was pretentious and condescending, and seemed unconvinced that something could possibly be wrong with his product, so I got a refund on the P.O.S. and bought an Emma Reezafratzitz (which is a similar, Marshall type distortion pedal) and never looked back. The Reezafratzitz is a pedal that won't disappoint.
The Echorec, I have to grudgingly admit, is fairly good. I've since moved on to a Diamond Memory Lane Jr. and found more satisfaction with it tonally, but I preferred the controls of the Echorec. It is laid out pretty well and the controls function great, and the only gripe I have with it is possibly just a matter of personal taste, but I found it slightly dull. I don't mean really in a bad way, but just kind of lacked sparkle or something. It kind of reminds me of the Maxon AD999, but the Maxon is like that because it's a warm sounding delay. The Echorec was just kind of uninteresting somehow tonally.
