The clock-less serial protocol we’ll be discussing in this tutorial is widely used in embedded electronics. If you’re looking to add a GPS module, Bluetooth, XBee’s, serial LCDs, or many other external devices to your project, you’ll probably need to whip out some serial-fu. ![]() Id like to make a list of Mesa Dual Rectifiers as I can't seem to find one. Any year info would also be great. These are the ones I know of (I'm sure i'll be corrected if i'm wrong ) Tremoverb Solo Roadster Road King Road King 2 100w (2010 Multi-watt version) I think some of these came in 2 channel and 3 channel variations? I'm not sure at this point heh. Every time I called somewhere in the past to ask about the dual rectifier the person never seems to know the difference and just keeps telling me its a 100w dual rectifier. Lots of good, accurate info here. If I might elaborate a bit, from the history perspective: Yes, originally the name 'Dual Rectifier' was indeed a whole family of amps, and what we now think of when we hear the phrase 'Dual Rectifier' was just one of them, the 'Solo Head'. You also had several other amps in the family, logdrum listed them already, no point in repeating the list. What they had in common was that you could choose between diode and tube rectification, hence the name. Weirdly, however, the Blue Angel didn't offer you the rectification choice, despite the name (which is what I believe logdrum was referring to). Instead, it introduced Progressive Linkage. The Dual Rectifier Solo Head went through several revisions before it became the 3-channel '100W Head' we have today. The milestones were: Revisions C, D, E: The first production models. Pembelahan mitosis pdf. A little over 500 were made, which is why some people call these the 'pre 500 Rectifiers'. These were originally targeted to 'big hair' shredders of the 1980s, hence the official name ('Solo Head'). Unfortunately, Mesa missed the trend by roughly 5 years. Nirvana and grunge were in, shredders were out. The sound and feel of these amps is unique. They are markedly tighter and brighter than anything later in the Dual Rec Solo Head product line. The first revision, C, is sonically closer to a Soldano SLO (from which its circuit was apparently plagiarized) than to a Revision G or a 3-channel Recto. The other two (D and E) got progressively darker and less harsh/brittle. The cleans of these early revisions are not cold, dull and sterile, only marginally improved in the D and E. Revision F: A notable step towards the more familiar Mesa Recto sound. The distortion structure is markedly looser than in the early Rectos. These still have Mark III transformers (like the 'pre 500' Rectos did), and their sound is brighter and more biting than the Revision G, which followed. Their clean sound is very much improved from the early Revisions. ![]() I believe that roughly 2000 Revision F Solo Heads were made. Revision G: The most common and most iconic 2-channel Solo Head. This is the sound most people normally associate with the 1990s Mesa Recto sound: huge, bassy, loose wall of distortion. Actually far more versatile than often given credit for, they have lots of great low and medium gain tones in them. The overall sound is warm; the cleans are definitely usable, if a bit dark-ish and not necessarily 100% clean. At least 10000 of these were made. Next came the 3-channel Solo Heads: 3-channel Solo Head: Brighter (and fizzier) than the 2-channel Revision G, with an aggressive lower-mid growl that makes this model eminently more suited for metal than the more general-purpose G. There is an added 3rd channel and new low/medium gain modes between Clean and Vintage High-Gain, but these new modes can be approximated on a 2-channel Recto (inasmuch as a 2-channel Recto can approximate the sound of a 3-channel one). The cleans of this model are not terribly good. 3-channel 'Reborn' (Multiwatt) 100W Head: The current incarnation of Dual Rectifier Solo Head, thankfully no longer labeled 'Solo Head'. That name made little sense after the initial C, D, and E revisions anyway - 'Rhythm Head' would have been more descriptive. The main sonic differences include much better cleans than in the early 3-channel models, and brighter sound in general. You could also appreciate 100W/50W per-channel power selection and the serial loop (instead of the parallel one that was stock in Rev G and early 3-channel Recs). Other variations Triple Rectifier: Doesn't add a third rectification option, it just adds a third pair of power tubes for 150 watts of total power.
