Nice build! I haven't built a Bluesmaster, yet.
But I'd have to have an external OD tonestack. I couldn't help myself tweaking the trimmers all the time!

I’m on a plane for 9 hours on Monday. So tracing this will give something to do.

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

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

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 ...

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...

Maybe more like this?

Thanks,
Aaron

Revised schematic on page 1

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...

Assume it has errors, has not been tested.

***REVISED SCHEMATIC***

Great photos! Thanks for these. Will draw a schematic later tonight when I finish work.

Thanks,

"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...

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, ...

Wow, great build! Beautiful work!

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!

Thanks,
Aaron
