The new rectifier was pretty nice but was lacking something for me. I would use an external eq for the lead channels to smooth out the grainy texture. When i put el34's in it there was a big improvement in the clean channel(more vibrant and glassy sounding), and a loss of bottom end in the distortion channels. I wish the standard recto had reverb, the clean could use it. Overall the amp sounded sterile, even with an assorment of tubes I tried out(6l6,El34,KT-66,and matched GT12ax7's).

The rectoverb I had did not sound as burly as the standard dual rectifier.I would not recomend the rectoverb as it was really muddy sounding although the clean had a fairly nice, good bouncy tube sound.

AS far as the tremoverb goes its 2 channels instead of three, and from what I heard the clean was amazing, one of the best I've heard since my old twin reverb. But I did not hear the distortion on it sooo.?

Your best bet, if you want the real recto sound then buy one, the other models have different features that set them apart from the regular recto sound. I'm assuming you want the kick butt hard core distortion that the recto offers.

I now play a mesa DC-10, which is a nice versitle amp but cant quite get the recto sound. But can nail metallica's 'and justice for all' sound (the amp has buildt in 5 band eq which is really nice) my only problem with this amp is there is way too much mid range and as far as all boogies that I've owned, none of them are very musical in character, ie its hard to get violin type feedback, they all seem a little sterile even through different cabs, guitars and tubes.
Hope this helps
