Hey RG, email me the manual and I'll have a look for you. Probably the main consideration (apart from gain structure/noise) with Fx is weather you want the next Fx to affect the previous FX e.g. generally you'd probably apply chorus followed by delay (so the delay(s) includes the chorus) followed by reverb. So with my rig, chorus (when I use it (mostly on clean sounds)) is applied in MP2, I send that (via mixer Fx sends) to Quadverb. I don't use the Quadverb chorus just delay and reverb. The delay is set up to feed the reverb ins (so serial) then mixed back in with the direct sound (which in this case also has chorus if I've applied it).
Boss/Roland gear all has the "Roland" sound/colour even their 3rd octave graphics (which is probably where my aversion started as they were often in PA systems back then when the PA owner couldn't afford klarkteknik or similar decent trasparent eqs). I find it muddy, (lacking transparency) and it's in all their stuff from amps to pedals to keyboards to mixers even drum machines (it's subtle but always there
). To their credit, they are well made etc and often well appointed for the price point. But hey each to their own, what sounds muddy to me may sound warm to someone else... And obviously people like them, they've been around for a long while now.
The next FX unit I buy will be a Lexicon, best reverb I've ever heard going back to the Lark224X.
