New rig update #3 - wire it up!

While I'm still waiting for the rack to arrive, I had a bit of free time tonight to wire up the new rig in an 80-for-20 manner... I started by replacing the power tubes in the Randall RT2/50 (with matched pairs of SED Winged "C" 6L6's and EL34's), connected everything with George L's cables, programmed the RP-93 to switch channels on the amps, and optimized the levels on the Lexicon MPX-G2. While there's certainly a lot of programming to do with the MPX-G2, I was at least able to dial up a basic patch with some light detuning and delay to get a sense of how the multi-preamp rig would fare... in a word... fat!

So a few things have changed since the original plan I put together a month ago... first, I've added the Mesa Rectifier recording preamp and 20/20 power amp to the rig; second, I switched out the Digitech GSP-1101/Control 2 pair for the Lexicon MPX-G2/R1 pair; finally, I decided to work with the Randall cabs I already owned instead of buying new Avatar cabs. Here's what it all looks like, courtesy of PowerPoint...



And here's how it's all wired up... basically the guitar signal is going through the Axess BS2 and ISP Decimator pedal into the front-of-amp FX section of the Lexicon MPX-G2. The Rolls RP-93 is used to split the signal out to multiple preamps. The Mesa Studio preamp (dry) feeds the Mesa 20/20 power amp and the Randall RA412XL stereo cab. The other preamps (Mesa Rectifier & Soldano SP-77) have post-FX added by the MPX-G2 then feed the Randall RT2/50 power amp and Randall R212C cabinets. This gives a wet/dry/wet setup where everything is wired up as follows...



Hopefully the 20-space rack will be here by the end of the week so that everything can be "formally" mounted & wired up!

Very cool setup... I'm working on setting up a W/D/W myself...

I have a question for you though...

What is the signifigance of having the mesa recording preamp in there?

Was that crucial to the W/D/W functionality, or was it just to serve an extra purpose?
