3-channel vs Roadster/Roadking vs Rectifier Recording Pre: gain pot value and bright cap value

What is the gain pot value and gain pot bright cap value on your amp?

1. 3-channel dual rec (2001-2010)
2. 3-channel dual rec (multi-watt reborn)
3. Roadster
4. Roadking
5. Rectifier Recording Preamp

Re: Mesa Recto Pre and Power Amps

the tube rectifier function in a dual rec head deals specifically with the power supply response. it softens the response, and is responsible for one of the elements of the rectifier amps "3D tone."

that combined with the lack of power section negative feedback in 'modern' mode is what makes the low end flex in and out, back and forth, because the low end resonance you hear (FEEL :shock: ) is not a static equalization curve, it comes from the speaker impedance in relation to what the amp is putting out, and flexes and shifts depending on what it's being fed from the guitar.

combine that with the 'modern' mode preamp's layered fundamental, asymmetrical (?) overdrive, and razor-blade cold-clipping circuit crock pot concoction of artery clogging slow roast tone stew, and you understand why they put f%&# diamond plate on the facia. :twisted:

to answer your question though, the 2:90 doesn't provide tube power rectification, but what it does offer that the dual rec DOES NOT, is Simul-Class power operation, which is basically 2 of the 4 tubes operating in class A, and 2 of the 4 tubes operating in class AB. I'm sure you're aware of class A operation being associated with low-wattage, flubby, slow, open, FAT tone.... :idea: So while the 2:90 doesn't do tube power rectification, the power section adds a SIGNIFICANT amount of coloration to the input signal, due to the simul-class power section. It adds the similar flexing effect to being pushed hard, only instead of power rectification providing the power flex, it comes from the class A half of the power section. (why everyone refers to the 2:90 as it being a 'musical' power amp)

Not exactly the same sound as tube rectification, because tube rectification feels like it comes from somewhere separate, almost like there is some sidechained compressor pumping the low end from 60hz down when you dig in... 8) but it does soften the recto pre tone in the similar way as the head power section does.

and at the same time, the 2:90 DOES offer Modern and Deep modes, which shift frequencies and resonance at the power section even further, to get it basically at the same weight class as the power section of a dual rec using tube rectifier power settings. i've never cranked my 2:90 outside of bedroom levels with the two modes engaged, but i would assume that because it does have some amount of negative feedback, it would be better behaved at crazy loud levels, whereas the dual rec will lose it's ability to resonate as well as it was if you push it too hard...the low end will sound absolutely brutal up to a point, and then if you go any louder on the master the low end will start to fall apart like lonestar cleans :roll: and you'll have to either reduce the gain or roll off a lot of preamp bass. good thing the master will blow out windows anywhere near 9 o'clock.

being that the Recto Pre is actually a self-contained approximation of the SOUND of a dual rec head, with the power section and transformers included, i can assume that the 2:90 would carry it well past the levels of decibel necessity and retain its fundamental bass resonance louder than an actual head would.

Re: Treated myself to the Roaster and OMG I'm in love

I set my amp up: Channel 1 - Tweed/tube rectifier/100w... Gain up enough to get an overdriven amp sound Channel 2 - Fat/tube rectifier/50w... Standard blackface Fender sorta sound. 50w helps it from sounding too "big" when switching between clean and high gain. Channel 3 - Vintage/tube rectifier/10...

Re: Roadster odd flanging effect on Ch.4 with loop on

I'm using a PODxt Pro in the loop, I turned the FX send knob up to about 2:00, and then turned down the POD output... that fixed it. you just have to noodle with it and tweak the knobs till it sounds good.

Re: Roadster odd flanging effect on Ch.4 with loop on

I got it sorted out actually, turns out that I wasn't matching the input/output signal levels between the head and the effects unit(s) correctly - the sound I was hearing was just an amplified version of the fizz that you get at low volumes with higher gain stuff. Took a couple hours of fiddling be...

TS shunts for 2:90 mode switching?

a footswitch makes a connection to engage the modern/deep/halfdrive...can you use a TS or TRS plug somehow hard-wired "shut" to just plug in back there to keep the modes always engaged? Thinking like a cut off plug of a guitar cable with the leads just wired together? I'm not an electronics guy but ...

Re: Rectifier to broaden my sonic palette?

The best setup I've had to date is a Roadster with a Studio Preamp (run into the loop return of the Roadster when I want it, all controlled via MIDI with a GCX)...I get AWESOME cleans, all the rectifier tones, and all the high gain mark tones I'd want. Something to consider....the studio pre is an ...

Re: triaxis still in production?

yeah i guess they do ask two different questions...it's like a word problem. you have to respond with a sentence.

so do you have to order it direct from mesa or through a dealer? I haven't found a new one anywhere online.

Re: 2:90 and two outs to one Cab

You can use your amp with a 1-step mismatch (8ohm tap into 16 ohm cab, or 4 ohm tap into 8 ohm cab for instance) safely Right. But never make a mismatch in the other way : never plug an output tap into a lower ohms cab, like a 4 ohms cab in the 8 ohms tap, or 2 ohms cab in a 4 ohms output tap. um, ...

not really worried about speaker damage, i've got a k100 and a V30 on either side of a stilletto slant...more worried about transformer damage from a tube dying or shorting, and all of a sudden 120v is going straight to the OT without any valves in the way. im not up on all the electronic workings o...

is there any damage that can occur (output transformer or other) from running tubes to absolute failure?
