This is my 2nd go around with this unit....I first tried it a year and half ago with my mesa RK II and the tone suckage was unbearable. But then I come to this forum and keep reading how great this thing is and how Egnater recommends it.... ...so I say to myself, perhaps I didn't give it a fair shake and maybe the software upgrades has improved the tone. So I sold my Eventide and purchased this unit again. I am two weeks into to it and the tone is just a notch below ok, no where near amazing. It always seems like the signal is compressed...though I never use the compressor and I have even bypassed the Insert Loop and went for Loop one instead for my preamp --still the same compressed signal. My guess is the AD/DA converters are at fault here. With the Eventide, my tone improved and never sounded compressed. I also have G Force, and it sounds wonderful...nothing like the G System. So folks, I really want to like this thing as it really is a great idea. I'd love nothing more than to consolidate my effects to just this board and an expression pedal and a couple of drive pedals in the loops....but I've spent too much $$ in my amp and guitars to have the tone compromised by this end end POS (at least as of now). In all honesty, however, my real complaint with the tone, where the suck-age is more noticeable is in the clean channels...the overdriven tones are not too bad and not as noticeable... I'd like to hear your opinions before send this back to MF and re-order my Eclipse (which is a pain in the ass to program...spent too much time programming instead of playing -- but it sounds great).
