"CONTENT" and "VOLUME" on a non-HRM? Just curious.
#155 has a "Volume" knob rather than a "Ratio" one and it is a non-HRM with shared master (by the looks of it). I can't see what the "Drive" pot is labeled as because the lettering appears to have been rubbed off.
Also, notice how similar the chassis is to the one in the YouTube video!
I got a reply back from Peter on his ODS. I asked him the serial number (the question which prompted the first sentence in his reply) and what tubes he was running. Here's his reply:
"Hi Brian,
I'll try to remember to look it up. Dumble also stamped my name on the chassis. Powertubes are 6L6's. There's no sag whatsoever, the poweramp is like a West Point cadet on parade who has had too much coffee so it's all preamp distortion. Glad you like the clip, greetings Peter"

I'm guessing that it has the Precision PS like #155 above which looks to be from the same era. Of course, it could be set up stiff with the traditional approach as well.
I can only speak for myself but I'd have to say it's virtually impossible to say only because of the fact that the amp seems to be on the brink of the HRM era. Could be a non-HRM with a Precision PS, could be a non-HRM that was upgraded to HRM, could be a non-HRM with Music Man iron etc etc etc.
How about the Content and Volume for the OD channel?
Do any other ODS's have that?
The tones on that clip are amazing, you can hear beautiful jazz tones like a fender with more bottom end through some early Clapton type tones , a clear blues tone and a very pure light overdrive, then a tone reminiscent of modern Eric Johnson with heavy OD but still pure and NO narly square wave or ugly tones ANYWHERE. AMAZING! Who can build me a preamp like that or a 2
or 10 watt version ? Are you guys building amps which can achieve these tones at this low of a volume ?!

I will belly up to the bar are admit that so far, I haven't built an amp that sounds like that.... but I haven't given up!

There are people here who can make them sound like that...look for the people who have the most builds with different variations on the circuitry; they tend to be the people who have the most knowledge of how little changes in the components or circuitry effect the sound. You could always buy a d'lite kit with the mod components and try the different designs yourself.
With most amps and preamps, when you hit a switch or turn a knob ,you get a variation of what you just had,i.e. a" gainier " sound or a bassier version of the same sound like turning a knob on your stereo. But notice the changes in tones on this video (and no doubt he could have done even more) seem to change the balance of harmonics in the tones or the relative amplitude of the harmonics , more like the drawbars used to on the old Hammond Organs. And it's mostly in the PREAMP(?!) since you can see the master is extremely low. Famous and semi famous amp builders for YEARS have been telling me how you HAVE TO BE AT A LOUD VOLUME to get great overdrive ( I never believed them, though it's obviously easier at higher volume). Well , here it is, the problem in replicating or surpassing these tones is how to get the gain and still keep the harmonics pure( and no fuzz or fizziness AT ALL )....and Dumble is/was an absolute genius at what he did, apparently. P.S. Thanks Dr. Who- I'd be more inclined to just Buy an amp or preamp from someone- I'm going to be recording lots of music and don't want to spend another 5 years on the DaVinci/ Dumble Code of magical tones, though an interesting subject.
I know nothing about these circuits, but I recently played 2 HRM Bluesmasters, and that's EXACTLY what they sounded like (in OD). The Eric Johnson reference is exactly the way I hear it too, there's a fuzzboxish quality to it.
Very different from the smoother Dumble Overdrive I had been used to previously (this was my first time playing a BLuesmaster, so I was amazed how different it sounded in the overdrive channel).
