I have TC Electronic Nova Modulator and Delay. I am thinking of replacing them with one multi-effect unit, just so I'm not trying to tap dance all over the place just to sync tempos. I just have a few questions about it that I didn't find searching (maybe I didn't search hard enough?)... 1) Can I use multiple modulations in series? Say tremolo into chorus into delay. 2) Can I turn the amp and cabinet modulation completely off?
