I got it for my dawless synth setup, to use on my saw leads, for that "wall-of-death-sound". Chained it up with delay before and reverb after... The grin on my face when I turned it on :) ... Just pure joy!
The sustain you get with that fuzzy distortion sounds just phenomenal on synths!
Apart from synth leads, I hooked it up on bass machines, drum machines... it just sounds great on everything for me. This pedal is my new main distortion and will definitively be used a lot!
