I have found when using on board dist effects on my Yamaha Cs1x that i can get nice distortions- but they are only good for solos when i play more than one note it gets mushy-
(like a soft red apple i like grany smiths)
I just what to distort a square wave- i want it to sound very distorted but be usable on chords-
e.g some guitarist say a pedal is good for solos but not chords-
