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.

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.
