Unexpected NAD - 97ish Mesa Tremoverb 2x12

Thanks!!

I had a Rectoverb 25. Great amp for the $ and 2xel84s. Same with the Mk V 25.

I found instructions on how to do the serial loop mod. Will be implementing once I'm past my return period at GC, or when something in the emporium moves.

I also read there's a cap that needs replaced to retain bass with the effects loop engaged. Jeremy recommended bypassing the reverb/trem. Haven't found how to do that yet.

Yeah, mine is the 50w head. I like it for its cleans and because it is super quiet. Still has the Recto grunt and sounds great with the Dual together. Can't speak to bypassing reverb but I just removed the tank :lol:

Not aware of a capacitor change for the loop but wouldn't surprise me. If mine has any less bass it is for the better because it is already bass heavy as you know. The C mod really cleaned all of this up and made it tighter for sure. Here the notes from what my tech guy did to mine if you are interested:

Ha. I'm glad he shares em anytime one of us newbies pop up. We should just go ahead and make a spreadsheet or setting form tho, labeled "Sawal's Mesa Recto Setting Guide".
I started the list in 1994, wish I labeled them, so I knew who's setting it is
 
Buddy came over and played with the TOV.
Here's an ambientish clip, Suhr Modern, Carl Martin Timmons compressor, flanger, KOT, EQD Dispatch Master, looper into clean channel.
He's quite persnickety about his gain sound, preferring fluid, saturated, ez to play, and thoroughly enjoyed the modern channel with a TS.

Hard not to love the old 2 channel Rectos. I dress mine up with EL34s for a slightly different flavor. There’s no wrong way.

Being originally (and kind of still) a Marshall guy, I like what 34’s do to the dirty sounds in my T Verb, but you definitely lose good characteristics in the clean channel. I’m actually using the clean channel a fair bit these days so I leave it 6L6 and just embrace the true recto sound on the dirty stuff.
If I could be really gluttonous I’d get a second T Verb to leave 34’s in.
 
I do like the 6L6 clean and sometimes miss it with the EL34s, but TBH I almost never use my revision G’s clean channel regardless of tube arrangement. I tend to use the orange vintage gain with low drive settings and like the EL34s in that capacity.

The idea of a stereo recto setup with both sounds like a lot of fun though. Brings me back to my Incubus days.

The clean channel on the T Verb is much more useable than a regular 2 channel. If I had a regular 2 channel I’d definitely would have 34’s in it.
 
I ran EL34 in my Tremoverb for about 20 years. Last decade back to 6L6.
I always keep a set of each and mess around occasionally.

EL34 in the Triple and 6L6 in the Tremoverb would be interesting. I pretty much use single amp rigs these days.
 
Now that I’ve got a Strat it’s opened up a whole new experience with my 5150 and the Tremoverb. I’ve always felt Recto’s shine with a bolt on neck guitar because of the usual, leaner low end coming from the guitar, but with a SC bridge pickup it is really f’n cool. Vintage gain on the Orange channel is just a delight of clean to mean on the volume knob and I can get the gain up to almost 3’Oclock without it turning to mush.
Plus the mids sit really well with single coils.
 
Made this clip, comparing the Scumback 65 watt Scumnicos to Mesa Vintage 30s.
Recorded with a Zoom Q2HD. Rhythm guitars on a looper, same amp settings. Only the speakers changed. I'm quite surprised how close they sound on my phone and laptop. Haven't listened in my truck or on my Yamaha HS8s yet.



DUUUUUUUUUDE!!!!!
The effects loop sux!!!!!
Even with nothing in the loop, and a cable intserted into the send/return jacks, it sux.
It neuters the ballz of the amp, affecting the feel and low end in a most negative way.

Can't seem to locate info I had found, on how to change the effects loop to series, that also mentioned removing a capacitor that is responsible for the "lack of bass" tone change.
I think the TOV mod may be different than a Rev G Dual Rec, because of the trem/reverb circuit.
PLEASE, anyone that knows, share the info how to mod the TOV effects loop to not be such a tone sucker. And/or how to bypass the trem/verb circuit.

I was going to compare a whole bunch of speakers, but am thinking that it won't make a huge difference in the open-back combo.
I was planning on trying an H75/V30 mix and 2 Scumback BM75LDs.
I'm not sure it's worth it.

I think the differences in the speakers will be revealed if I do these 2 things:
1. Turn off the effects loop. It's a massive tone sucker. Absolutely needs modded.
2. Use real mics at louder volume.

Will experiment and get back to this.

Don’t know what year my T-verb mine is but the loop (parallel) has no negative impact on the amp at all. I just leave it at 100% amd occasionally had an EQ pedal in there. Granted for a over a year now I’ve used a PS2 for everything and use it’s loop.

TheDannval on YouTube has a video on modding a recto loop to be serial. Not sure if it applies directly to a T-verb but I don’t see it being all that different.

My Tremoverb was a '96, and for years I avoided the loop because of exactly the same reasons as @LPMojoGL. The fix for me was a combination of things.

Replacing the Chinese high gain ECC83 with a lower gain NOS GE/JAN 5751. It reduced the extra gain and compression when running the channel volumes and fx send at hotter levels.

Lowering the gain to around 12:00-1:00 at most on the high gain channel which mostly balances the huge volume disparity between the dirty and clean tones. It also trims the lowend boominess from the high gain tone due to the preamp design.

Cranking the channel masters as high as possible while maintaining the balanced volume levels. Generally clean channel was at max, high gain channel around 3:00.

Cranking the loop send and return. This does require having high headroom fx that can handle a hot line level signal. Might not work as well with boxes designed with mostly instrument level signals in mind. I am also 100% sure using the lower gain 5751 helped make this possible.

Using the Loop Active master for overall volume.

To my ears the loss of teeth and balls, the over compressed, undynamic, blanket over the cab tone completely disappeared. Whether switching the loop on and off, or switching my fx out of the path via my tbp pedal switcher the amp sounded just as dynamic, big, ballsy, cutting, and mean af. The only difference was at lower Loop Active Master settings vs loop bypassed because the huge jump in volume between the two with the channel volumes that high. At lower Loop Active Master settings it is very present, cutting, and a good bit stiffer then you'll expect from a DR. Once the Loop Master is above 12:00 it starts to thicken up, bloom, and gets chewier to play.
