Right now I've got a MM4 I've had for years but rarely use. I only use it for bias tremolo and rotary speaker sounds. What I like about it : 1 - the bias trem speed/intensity following effect. 2 - I have whatever the expression pedal L6 makes for it to morph from slow/fast on the Leslie stuff. What I don't like : 1 - limited usable effects 2 - power requirement 3 - limited presets So I'm wondering if maybe a M9 or HX might give me what I like and change what I dont. I'm satisfied with the tones of the MM4, just curious what's out there and since I don't keep up with the modeling stuff I figured I'd ask the panel of experts for their (your) opinions. Thanks in advance!
