I know they don't get much attention around here, but does anyone have any experience with them? They are pretty cheap and some of the samples sound pretty good.

I have the Tweak Fuzz and I think it is quite good. It is similar to my Dirty Boy Cannibal Boy Fuzz,except 310 bucks cheaper.
I'd try it out,if you like fuzz,it's a good one.

I have the Twin tube classic along with lots more tube/non tube pedals and I think it's the best if your into 70's type rock(Trower) it has a very brown vintage sound-very dynamic. I give it a very enthusiastic thumbs up! It's the pedal I use most!

I have the Shape Shifter Tap Trem and like it a lot. The signal path is 100% analog, though some of the controls. are digital. It's extremely versatile with controls over the waveform from sine to triangle to square and the duty cycle (how long it's on vs. how long it's off) as well as depth and speed. I think any trem sound you would want is in there with a bit of tweaking.
