I might just go for the chance once I get back to the states (I'm abroad for a few months). I think I really like the basic sound of my dual recto, just wish it was a bit tighter...I don't have my recto sounding anything like the recto sample on the egnater sight, but it does give a good hard rock tone. I also need to do a retube of it. Maybe if the financial situation works out I'll see about ordering a mod 50 and testing them side by side and then putting the other one on e-bay. speaking from a practical point of view, I'd be much easier to part with the dual recto since they are pretty easily available.
I wasn't aware the mod50 had a half power mode? Care to talk about it a little bit? and how is changing tubes/biasing it? Can someone with no experience with that do it? The mesa fixed bias is pretty convenient for that.
I'm guessing the MHG or maybe even the E3/E4 would be module I'd go for, unless the e-rect can sound a little more like a recto with less gain. To give you guys an idea I usually run it either in modern mode with gain at 10:30 or 11 o clock, maybe if I'm in vintage mode It'll go a hair below 12, but i usually stick around that zone.
Thanks,
Diego
quick edit: also, especially from those that came fro the dual recto or other 100 watt amps, how does the tightness compare to handing lower tuned stuff. I like standard tunning but the band I'm in tunes to drop C # (drop it a half step then drop the E string a full step from that). I've never had a 50 watt amp head, only experience is with my 100 watt recto. I'm keeping my fingers crossed the financial situation works out and maybe I can be lucky enough to keep both for a week....
