Post a gut shot if you have one. Shouldn't be too hard to trace.

Re: Ultraphonix adventure

Yes, the schematic has the wrong values. I thought I had updated it. Sorry for the confusion.

Re: Overdrive Deluxe amp

Ok I took one for the team and made a couple clips with the amp at volume. It's ridiculously loud, but once I got it there I realized it was doing the thing we're all lookin for....at least very close. My sloppy playing reflects the fact that I was completely a deer in headlights, as I was shocked ...

Re: Overdrive Deluxe amp

Version 3 attached. I think we're getting closer. Judging by the physical size, the preamp Ck look smaller than the 25uf used through out the rest of the amp. Guessing they could be 5uf? @Smokebreak3, Taylor has 5 filter stages in his version. Regarding the HI and LO inputs, still a bit of a mystery...

Re: Overdrive Deluxe amp

Slowly making way through the schematic. This is where I'm at so far. Assume it has errors, a little bit more to go. Thanks, Aaron Couple things: There’s a cap connected to the treble cap entrance. Is the rock/jazz switch possibly being used as what we usually know as the mid boost function instead...

Re: 79 Dumble Overdrive Deluxe

"Mid switch instead of Rock/Jazz" Hmm , on their website they definitely label it as "rock jazz" tho , look it up : https://amplifiednation.com/product/trem-drive-deluxe/ Look at the switch, its a SPDT, not DPDT/100k/.01uf as per Rock/Jazz. Look at the tonestack, has 500pf and .002uf?, I'm guessing...

Re: 79 Dumble Overdrive Deluxe

Thanks for the gut shot. First thoughts, looks Low Input is 5F6A based (cathode follower, tonestack) and High Input goes through an extra stage for JCM800/Ultra Phonix Gain style. Standard Reverb circuit. Mid switch instead of Rock/Jazz This amp also has the "Bug Trem" instead of Bias Trem. Thanks, ...

Re: Overdrive Reverb/Steel String Singer Hybrid

I’ve been doing a similar build for the 10 months. But with tube buffered loop, left/right return into 2 x 50 watt power amps. Only 12 valves in total!

Re: Tracing Rick Vito's ODR #58

I remember looking at this a while back, and the mixer reminded of the earlier circuit, ie: ODR #013.
This is the only other photo I have.
