ThanksIMO the acoustic ch is not as good as the regular clean channel or the sneaky twin for getting a fender clean amp tone. The sneaky amps twin will do that and if you use the "custom" amp model, theres a sub menu in that where u can choose the twin and it adds 5 more tone controls including PRE distortion highs and lows and a character knob that goes from totally scooped to full on mids. To me at least, if you have a katana and want clean electric tones thats where ya go, period. It not only sounds better IMO, but i think the feel is more real, and to me it's the feel where most modelers fail at recreating fender cleans. I didn't feel even the old and new mustang amps (had both) had true tube amp feel at all, not even close. The sneaky twin gets closer then any of those or it's own front panel clean IMO. As with anything YMMV, but like i said, "to me".
