Hey All,

I have really never been into rectifiers. But...GAS, so of course I bought a bunch of rectifiers. When I was first starting to play guitar the rev g and 3 channel rectifiers were everywhere. They sounded great on recordings...but when I got one I really didn't care for it at all. Fast forward and I learn about the different revisions of the rectifiers and think "well, this is interesting. Let's see what it is all about." Luckily I was able to track down a revision C, D, and F.

I read a lot about these amps and had a lot of expectations about how they would sound/behave relative to each other and I was dead wrong on basically all fronts. To get this out of the way this is not an apples to apples comparison as the D/F have EL 34 and the C has 6L6. I'm not sure how big of a role that plays in what I heard. All amps were checked out by Mesa within the last 2 years also.

The C has a reputation for being the tightest of the 3 amps. I also expected the D to sound basically identical to the C but maybe slightly more loose and darker. Not the case. At least with these 2 examples. The C is tight, but not as tight as the D. The C also is more saturated, has more hair, and more apparent gain. As a consequence, the C actually feels more forgiving and easier to play than the D. The C is the brightest and also has the least low end. It also feels the most raw to me and really does remind me of my SLO in more ways than I expected. When I hit it with a TC integrated preamp, it reminded me of my original 5150 with a super high output boost on it. The saturation level, harmonic data, even the feel to an extent. It just sounds like a better version of that for what I like. If you bring the gain down it sounds drier, less saturated, etc etc, but it still does not feel nearly as tight as the D.

The D sounds very mix ready. The structure is a lot more uniform and the dynamics seem more streamlined. The amp is fairly dry and tight relative to the C which has a lot of hair. The comparison I would use is if the C is a Marshall, the D is a wizard. I mean that in terms of feel between the 2 amps and the C having a more raw quality and the D feelings like it has a more

The F is fantastic. Has a great feel, still has great dynamics, and the voicing is distinctly different as the mid emphasis has changed to push the low-mids. It is amusing the F is so heavily associated with metal (which is fair given it has been on some great albums), but it feels the least metal to me. The sag in it really makes me want to play the 90s alternative tracks more than say Trivium. When I am on the C or the D it is hard not to just default into the heavier stuff since the amps are so tight and aggressive. The F can do that but the feel makes you play differently.

Anyway I like them all. I also will say I know that the amps can all have a large variance between each other even amongst revisions. If you play 2 rev F there is a good chance they will sound and feel different (even with a health check etc etc). So take my opinions with a grain of salt.

Nice! I've had all the Revs but D. I really did like C but it was so bright it would cause my ears to ring afterwards even at low volumes (that's probably just a me problem), but man it sounded great. Very aggressive. I liked it way better than any SLO or 5150 I've had.

I've had several Fs and they all sound the same, which is awesome. Not as tight or bright as the C by a long shot, but just an all around great amp.
 
Killer! Have had 2 F triples, and a Rev C....the C was far and away the winner of ALL the Mesas I've owned including the C+s. Like you stated, it did remind me of an SLO but with some Marshall DNA as well, but a heavy low mid push. The mids were the biggest surprise as I could dime them and it never became honky, or nasally. And, the Bass could also be dimed to give it a nice large low end. Killer amp. Another aspect was, it seemed to push air like a Wizard, Superlead or SLO in that it sounded/felt like more than 100 watts. Most Rectos seem underpowered vs their rating.
 
Nice review! It is basically what I hear when comparing my C to my F (and G that I had). The feel on the C is just different. The F and G have this rather sluggish and bouncy response.
 
Nice...which one sounds like a Soldano SLO 100?

It looks like you're holding your schlong in the reflection of the chrome chassis.......
Yes...looks like....

Also I think the C is the closest to the SLO. I have an old 1991 next to them and there were a lot of similarities. The C is more raw sounding (maybe even than the SLO). It had a lot of harmonic data flying out of it and had that liquid SLO lead thing going on where it can make it very smooth to play. The C is much more saturated than the other two...The C had a lot of commonalities with the 5150 in terms of juiciness, but it was voiced like the rectifier (if that makes sense). But the chords still sounded very aggressive and grindy. So even though the leads were smooth the chords were pretty crunchy which was a pleasant surprise.

Having had myself a C, D and F next to my ‘89 SLO, none of them imo really sound or feel like the SLO, but the closest I got was the Rev C loaded with 5881’s (important to get more SLO-like). There’s something distinctive in my ‘89 SLO’s mids and uppermids that my other amps don’t have the same way

I agree for sure. It is versatile also in the sense that you can thin it out and still dial in body to it, which is cool. It is ass poundingly loud. Even at 3/10 your ears will ring. No Doubt. Totally agree--you can get a sizeable ass end to it without it smearing the other notes as much and having it mud up and get overpowering. The gain section can be set to have it sound like a lot of negative feedback (and all that comes with it) or have it fill out a lot of body while maintaining a great deal of clarity. The C also seems to have more gain on tap or at least more apparent gain.
 
Congrats on have all those 3 Rev’s!!! One thing I’d recommend when AB’ing (which I did) is to literally use the exact same powertubes when comparing. I believe my C is pretty close to your in serial #. With my C I’d agree with a lot of what you said, but with that exact D I found my C to be tighter, faster tracking and actually have a more extended low end, but less low mids vs the D. I haven’t liked as much so far 6L6’s in my Recto’s, but really like 5881’s surprisingly, but EL34’s ftw to me and some US 6CA7’s are cool too

I definitely think the C is the closest but does not feel like the SLO. The SLO is a lot looser. The C is significantly tighter than the SLO (oddly the C I have is looser than the D...which was not expected haha. That could be the tubes I suppose also). I also think the voicing is not the same. The C is very metal and has a lot more grind. I suppose what I was getting at was the saturation level and ease of lead playing reminded me of the SLO vs the other 2 which are a bit drier.

That's a solid point. When I get some time I will have to do a complete tube swap between them all to really get an accurate picture. The one good thing is all 3 of them are so different in terms of feel and sound right now that I can substantiate holding all 3 for right now since they act so differently. But I do sense a tube swap coming soon.

Yeah the SLO has this distinctive rubbery feel to it that the Recto’s don’t have imo and is smoother than Recto’s. I’d check maybe also the pre tubes in the C. I remember my C and D seeming to be more or less similar in gain

Yes the feel of the 3 are different for sure

That's interesting. On these the C seems much more gained out. At least on the tapers. If I want to match the D level of gain on the C I have to turn it down about 2 notches to get them in the same ballpark.

Yeah tapers can definitely vary. I don’t remember anymore in that regard. I guess I just remember them being similar when dialed in how I liked both best
 
I'm pretty sure the C has different pot values (gain, presence) vs the other Revs. When I did the C mod to an F triple, the gain pot value doubled. I also agree the feel of the C is FAR different than the other versions...very bouncy and similar to a C+ but not quite at that level.
