I got these pedals to review and pass along, so the review is a little biased in that I didn't purchase these. The PMC and MKII are both modified Boss DS-1s (no added controls). The Elmore is a proprietary box with two controls, volume and focus. I played through my Bad Cat Cub IIR and A/Bd them against my OD/Distortions (Fulltone FDII, GT-500, and OCD V1). The MKII is very dark. I didn't play it with my band, but I think it will get lost in the mix. It had a good amount of distortion and volume (more than a stock DS-1). The PMC was more musical and less dark, also with a good amount of distortion and volume. I think both pedals are well built, and would probably work for some players. I found my GT-500 and OCD (closest in gain structure) to be more musical and natural sounding, whereas the Occtones seemd to color the natural tone too much for my tastes. The Elmore is a clean boost similar to the Fulltone Fatboost, so I A/Bd it against the boost side of the GT-500. The Elmore didn't have as much gain as the GT-500, but had a little bit of fatness to it. The focus knob mentioned above seemed to change the tone and gain structure very subtly. I found it worked much better on an already overdriven amp (either naturally overdriven, or by a pedal). Again, not my cup of tea, but a very nice and musical pedal.
