Why would the FET jack be isolated when it is grounded right to the normal jack?
I think I wired mine like the #124 layout shows.
Mine seems to work ok, although I am currently having a intermittent on the FET jack which I believe is the switches on the jack that need to be tweaked.

Sorry for the mix up.. I got confused with a different Fet circuit I built in several other amps + on vacation and drinks are good here.... The Standard FET circuit Dumble uses the jack should have an isolated break function, like the switchcraft 13E type (Dumble uses a nylon bushing version with similar functionality). The way to wire that is: the output of the FET goes to the switching contact on the normal jack, such that when you plug into the normal jack, you defeat that connection and get your guitar's signal straight to V1A. Then, the switching (independent break) part of the FET jack connects the output of the FET to ground -- and that connection is broken when you plug into the FET jack.
The reason for that is, if you don't ground the output of the FET, you will get a lot of hiss when nothing is plugged into the amp. If you don't care about that, you can use two regular jacks and live with the noise -- unnecessary IMHO..This one should work fine!!
Hope This clears things up..

Hey Tony, I'm on vacation this week too and I keep getting e-mails from work. We should probably tell our customers to bugger off until Tuesday, right?
A friend of mine came over today and we spent some time dialing in some sounds on the amp (I dialed, he played). Here are a couple of clips, one through NOR, the other FET. We also used a Dumbleator clone (C-Lator) and just a hint of delay. Mic was in front of the EVM 12L speaker in my 2x12. Otherwise captured straight in and mixed with the backing track, no extra stuff.
Nice clips Sonic
your friend plays well and has really cool chops
what are you using for recording?
wondering what amp controls where set at during recording?
amp doesn't seem to sit in the mix as well as other clips I've heard here
seems a little muffled...IMO which should be taken lightly as I have not
posted any clips.
I recorded with an SM7B mic into an Eleven Rack mic preamp.
Here is a pic of the settings when we were on FET which was about the same as when we were NOR. Be aware that somehow my switches on the amp turned out upside down (I must have different type switches from the layout) so actually it is Rock=On, Deep=Off, Bright=On, Accent=Off. C-Lator is other way and brights switches are Off. The way I wired it, the C-Lator into my Power Amp In jack bypasses the Level on the amp. That input and impedance selection were the only added features to the stock 3rd gen layout.
That's all for now. I've got an extended vacation coming up starting tomorrow and in about a month I'll probably get back to tweaking it some more but I am very pleased with how it sounds already.
Here's a longer final version with clips combined by my friend and mixed a little better. We did go for a slightly darker sound.
Very nice clip...darker in a cool Santana kinda way
really nice playing(really cool lick/scale near the end). Congrats on an outstanding looking and sounding build Sonic...enjoy your vacation.

Humbucking pickups?
Are both speakers in your cab EV 12L?
The guitar used was a PRS style copy (Tradition) with humbuckers. My 2x12 right now has an EV and a G12H100 in it but on these clips we just mic'ed the EV.
