I've started looking into these pedals and, considering I will soon buy a seven string guitar and downtune it just a bit, one tone, nothing too extreme, I don't want to end up with a muddy tone. I play (yeah... that's the idea) technical/progressive metal and the amp is an ENGL Ironball. A good thing would also be a noise gate integrated into the pedal. Up to now I have found these two: Amptweaker - Tight Drive jr Horizon devices - Precision drive Any suggestions? Thank you!
