Got to demo the pedal yesterday. Very nice. I A-B'ed it with a 2-channel (clean/dirty) Jose clone amp a friend had and actually I liked the pedal better than the dirty channel!! lol Lastly, yes, internal pedal gain pot was set mid-way and of course clockwise adds additional gain and distortion. I wanted to see if I can get more of a "boost" out of it, but even turning it all the way down, it was still dirty and breaking up. I'll keep playing with it more this weekend and thru many other amps. Maybe it should have been called the BE-DIST thou?!? Tone is very good thou and pedal is quiet with those dual JFET IC's!
"plexi or early JCM 800."
As far as how would work on a Plexi or JCM800, it will work just fine, but have to be adjusted depending on the amp and if it's dirty. The Fendery amps will be bright, so need to be adjusted accordingly. Ideally, this pedal would work best through a low-gain Plexi or Clean amp or amp on the clean setting, bt when used for that application, sounds fantastic and very, very tube-like!
The only negative(s) thus far is the pedal is very dirty (as seen in the video). I've tried to dial it down and with the internal trimmer as a boost and it still breaks up. I'm really thinking this should have been called the BE-DIST as it is much more of a distortion pedal than an overdrive. Then then Dave could have released a second pedal, with different component values and possibly take out some gain stages and called it the BE-OD "OR" have a switch to cut out the gain stages in one pedal and just call it the BE-PEDAL and people could make it a boost/overdrive or distortion pedal. Just throwing some shit out there. Maybe Dave will/has some ideas...but there is a ton of gain and it's more of a distortion pedal than an overdrive and booster is non-existant.
p.s. - Oh, looking at Rezamatix's gain setting and getting soo much distortion, I would say he has the internal trimmer cranked. If you're going to use it with that much distortion and metal over distortion pedal, fine, but most people will enjoy it in the middle how mine arrived.
