Do any of you use the D type amp/speakers for non-jazz?

Bascially - non-master, non-HRM with reverb, low plates on V1, .02 mid cap, larger bypass caps and smaller coupling caps - especially the PI entrance (.005).

I do love the sound of your amps... but doesn't these changes really take the amp far closer to a slightly modified fender topology then a modified dumble?

Unless you completely ignore the OD section, I don't think so.

But he mentions no Master volume, so the "OD section" is just another gainstage. Since blackface fenders use 3 halves of 12AX7 tubes in their vibrato channel, the number of gain stages are almost equal. Basically a fender with one added half of a 12ax7.

I guess the best was to answer this is to say something like "If I only modified a Fender this amp would not sound nearly as good", or "If I hadn't built this like a Dumble clone it would not sound nearly as good".
To my way of thinking it is a lot closer to a clone than a Fender. If I'm reading you right you would think amps like #124 could be considered Modified Fender's. Which is probably true but Vive le difference!

There's a Master volume - it's a 1 meg resistor to ground at the appropriate spot - so it's the equvalent of 'Master on 10'.

Not quite, you had quite the list. No master, big bypass caps, very low PI input cap...etc. At some point we would be splitting hairs since dumble's original concept was a Fender Deluxe on steroids. I just read into your changes to bring a dumbles normally middy bulge closer to the scooped fender sound. Sorta like splitting the difference between a dumble and a fender.

The non-master is admittedly a big deal, but the number of gain stages isn't terribly relevant when they're used totally differently. Besides, the OD section makes a total of 4 preamp gain stages, 2 of which are sometimes in, sometimes out. It's a pretty big difference. You can change those values and take out the master, but at very least when you kick in the OD, it does something a stock Fender never did.

The "middy bulge" comes right back when you engage the mid boost.
