I hear a lot of people complain about the parallel loop on the Rectifier series. I have a Tremoverb and the loop was driving me nuts... mostly because the amp sounded 10x better with the loop bypassed! With the loop engaged, the amp lost quite a bit of attack, beef, clarity, bass and gain - some of that could be dialed back in with the tone stack, but not the attack, beef or clarity. The amp just felt and sounded "bigger" with the loop bypassed.
I tweaked that sucker pretty much all day today and found a way to "dial" the oomph back in while still using the FX loop. On the back of the amp, set the send level to as hot as you can without mucking up the sound of the amp or the effects in the loop. Mine was straight up at noon, but then I set it to about 2 o'clock and the beef was back! The amp sounded as good (even better actually!) than it did with the loop completely bypassed.
Obviously, YMMV. A few other factors to note... my mix level is set at 100% so the loop is in theory acting like a serial loop. I'm not sure how this will translate to the 90% max loops on most Rectifiers. I set the loop on for both channels. I also had all of my effects routed in a true bypass loop box, so there was no tone loss due to the pedals. I've done a lot of searches on this topic and never read anything like this. It might just be me and my setup... but I thought I'd share.
