Interesting. Any idea why a global master separate from channel volumes would require a parallel loop?That's one thing I wish they'd kept standard on all Rectos, a master Output separate from the channel masters, but I think the way it was designed (and someone please feel free to correct me here) required the dreaded parallel FX loop to make that particular setup work. Not that they couldn't redesign it, I'm sure, but players must not have cared much. I like smoothness and compression anyway, and I find that I'm more likely to set up a compressed, singing lead tone and then alter my right hand attack for rhythm than to dial in separate sounds for each, so I'm not in dire need, but it would be nice.
I really hate mesa's design, as I've made abundantly clear elsewhere. The channel volumes determine the send to the effects processor (as they should), but then you have no way to attenuate that after the loop. And if the loop isn't unity gain, it sounds bad due to signal bleed. You wouldn't have that problem at all with a separate preamp and power amp.
The means that:
- you can't have a noise gate (or any effect that depends on input level) in your loop that is calibrated for all volumes
- you can't use a volume pedal (or any other attenuating device) in your loop as a master volume.
Due to this my poor MkV:25 is relegated to being a lightweight mono tube power amp, as I'm using a separate preamp hooked into the effects return.
