Hey, thanks for the kind words! I have not posted my Jerry preset just yet, I'm still dialing it in since the move to the AX8 from the AxeFX 2. However, the basics are the Double Verb amp, spring reverb, and the IR that Jay Mitchell helped me make of my own 2X12 open back Hard Truckers cabinet loaded with JBL E-120 speakers back in 2008. That IR is floating around but I can post it if it's not easily findable.
It's also important to recognize how Garcia had his Twin Reverb set up, which was typically with the treble almost cranked and the bass almost all the way off. That really helps the guitar sit in the mix.
The preset itself is dependent on having a guitar with the DiMarzio pickups, onboard effects loop setup and unity gain buffer that Garcia used. It doesn't really sound right without that combination.
The guitar's effects loop sends the signal out from the pickups to the effects at full strength, then comes back into the guitar where it hits the volume pot, and you can toggle the effects in or out of the signal path. This basically makes the guitar's volume pot function as a master volume when you are using effects. While this is the antithesis of using the volume control to be expressive with, say, an overdrive, it does allow you to set the sweet spot on your effects and never adjust them, whic is great if you want to use an envelope filter (like a Mutron) or having your overdrive sound be identical whether the guitar volume is on 2 or 10. You can always plug the main output of the guitar into a pedal between it and the amp, too. Come to think of it, you can do that in the AX8 depending on where you deploy the effects loop.
The preset has all the effects Garcia typically used -- octave, Mutron, phaser, overdrive and delay, plus a 6 db volume boost, all controllable from the guitar.
Will post a video tomorrow of a song using the Mutron patch I worked on, and the particulars of that. Again, it works great with the effects loop, so it will take some dialing in to use it on a conventional guitar.
Speaking of guitars, that guitar was built for me in 2007 by a builder in Florida. It's a good looking guitar, but they made a fundamental error in placing the bridge in the wrong spot, so I had to have it drilled out and replaced with ebony plugs, then redrilled and placed in the correct spot so the guitar would intonate correctly. (Actually, I had Garcia's luthier do that part and also rewire the guitar.) So, I would not recommend the original builder. They made the same mistake on at least two other guitars that I'm aware of. Yikes.
