I currently have 2 H9 units and a Timefactor. I use the TF for delay, one H9 mostly for Verb at the end of the pedal chain, and the other H9 for Modulation, verb, wah, verb before delay, weird stuff, etc. All presets controlled with a DMC-6D midi controller. I have 3 expression controllers.
Pedal chain for my eventide section:
H9(misc use) – Timefactor (delays) – H9 (mostly revers)
Should I go to three H9 units for ultimate flexibility or is it worth keeping my Timefactor delay for the ease of tweaking real knobs. I do like the extra knobs I have on the TF for live tweaking.
