On the model 12 I like the fact that you can get compression and EQ on any channel with direct knobs. Would be perfect if reverb type effects were also available with one more knob. I can get the effects running fairly easily via AUX 2 but the current effect chosen seems to apply to to all channels. Can you choose a different effect for each channel. Have to admit I have not tried too hard to do this. Thanks for your input!
