Tonight, I tried some different setups between my Recto and a Line 6 Pod X3 Live.  I was trying to get a good headphone mix for silent playing.  The “Slave Out” was making noise and I switched to using a send from my Nova System to the X3.  I found the similarities between the modes to be quite minimal.  It was striking, really.

Mission Improbable

There are a few reasons I’ve been spending so much time exploring the Dual Rectifier.  Those reasons include: misinformation, biases and myths, and helping others.

The misinformation takes many forms.  Sometimes, it’s just reading about the DR having “active EQ” (false), that it isn’t a “solo” amp (false), or other equally dubious claims about the design that are ridiculous.  Biases and myths also fit in with the misinformation, but are just as much about the insecurities of the users as any misunderstanding of the amplifier.  Claims about early revisions being “superior” or the utility of the 2001 3 Channel version are as ridiculous as the circuit misinformation, because it’s all subjective.  If I was a little more cynical, I’d even think the second hand market is involved in promoting and spreading this kind of bias to increase, and retain the increases on, the obsolete designs.  Seeing as how Mesa designs them, builds them, markets them, receives feedback, and profits most from the sales, if the old amps were superior, they’d swap directly back to it due to customer demands and complaints.

Disclaimer

Guitar amplifiers contain lethal levels of electricity.  If you work on your amp, it is at your own risk.  This site doesn’t recommend anyone without the necessary training and/or experience to perform work on an amplifier.  Even trained, experienced people can receive electric shocks from time to time and I don’t wish for anyone to injure themselves.  Additionally, soldering on PCBs can damage traces if care is not used.  Any potential damage or wear is the fault of the person performing the work and warpedmusician is not liable for any limitations of the materials or skill of the person performing modifications.

My current main gear is a LTD AX-2E and a 2006 Mesa Dual Rectifier.  I’ll speak briefly about each:

The LTD was second-hand and had EMG 81/85 when I acquired it.  I later swapped the EMG out for Duncan’s JB/Jazz set.  This is probably the best “cheap” guitar I’ve ever owned.  It’s odd shaped, but the ebony fretboard with neck-through design is awesome.

The Mesa DR is their original three channel design.  It’s often vilified as a less desirable amp than the 2 channel originals; especially now that the new design is out.  My amp is not modified, but I may jump the effects loop to make it serial.  I use Clean, Raw, and Modern with Bold and Vacuum settings.  It’s a trade off.  In a few years, I might switch to a Reborn Recto, just to have silicon on the Modern mode and 50W on the Raw.

Diode in Tube Amp larger

I am building an amp and I wanted the ability to add another stage for distortion.  Unfortunately, I have some issues which will prevent me from using another 12ax7 stage.  Looking at some high gain amp examples, I noticed that a great many of them contain one stage that is biased so cold and at such a low amperage/high voltage, they go into severely hard clipping that is a square wave with rounded edges.  Because of the bias point, one side of the signal is going to clip much more than the other; this is called asymmetrical clipping and tubes do it naturally and very well.

Diodes are a low cost way to add distortion.  If designed with some foresight, it can be designed to be “tube-like”, but really doesn’t sound exactly like a tube on it’s own.  Placed between stages, it will get enough filtering through the tubes to not sound cold, hard, or whatever the purists like to say as they push their amps with solid state pedals.
