I would guess that an obvious mod would be to incorporate a push/pull switch on the Bass pot(or separate switch!) so that you could switch in and out the 0.02uf cap. Then you would have a 2nd/3rd gen hybrid!!!! Try it....it definitely makes for a more versatile tone stack.
I have the 0.001 on the bass pot now.
The amp is sounding good. I ditched the external OD trigger and put in the standard OD network. Wired in a feedback lift for more "raw" when needed. I also have a Minimix 2 and G Major 2 - the effects now sound superb and transparent too.
Sorry about the phone photo...
100w 2nd Gen Hybrid, Dlator, TC G Major 2, Suhr MiniMix 2, TL 806 cab with 16R Swamp Thang.
Damn screen printing got scratched loading in and out of the head cab so many times. I'm going to try and touch it in. Put the decal on yesterday but it crumpled on me. I will try again today and upload a better photo.
I have the NFB lifted most of the time it seems unless playing very loud - just sounds good to my ear. Maybe the NFB is wrong somehow, I'm not sure.
Thanks for all the help on this and for the 2nd Gen Hybrid information, really appreciate it

IME chewy is how hard you hit the strings with your picking hand.
Took me a while to figure that out. Before the DIY Dumble Bug, I listened a lot to SRV, played fender amps and used to hit the strings just like stevie. however, robbens (cheey) tone is acchieved by playing with a much mrr soft attack.

I was only kidding around about chewy
I have been using soft almost stroking attack for years on the D-styles. I also pick up from the pick guard and out rather than side to side across the string in the same way as EJ.
I can get chewy if I set things up that way, more gain and generally neck pup or bridge with tone rolled back a little esp with HBs but varying the pick attack as needed.

Gotcha.
regarding picking techniques - Exactly! Thats the way to do it, but, seriously I think that small detail is often overlooked.

Whenever I turn up at a jam with a d style, some one always wants to play through, they then thump their strings and generally it will sound awful. Once you show them how the pick attack works, after looking in disbelief, they try it and then the smile appears on their faces. It's all about getting some dynamics into the playing cos the amp will respond.
It's the Dumble moment right there.
Roger,
Did you adjust the OD entrance on your build? I just built a new 70's and put a whole bunch of stuff into it, the amp is sounding great, but the OD balance is way off. I put a clean master on the amp, which I think might be the culprit, I've been playing with pot values...but I'm thinking about changing the OD network to see if that helps.

I took the clean master right out! Didn't like it straight away, so I rewired it to standard ODS style. Well it is a hybrid...
Who knows what tapers I've got, though. I've got OD Drive and volume on like 7 and Master on 4.
Sounds fantastic so I don't really care where the pointers are pointing
I think that clean master doesn't work that well with the 2nd gen preamp...I dropped the resistor after the v2b coupler way down, it balanced it out pretty good. I think that has a bigger impact than the OD entrance
I've always found this issue confusing. In what way does the sound differ using the separate masters? Surely, with the hybrid layout, all you are doing is switching between two 1meg pots, allowing you to have more control over the gain/volume of the OD relative to the clean sound. Are we saying that the OD sound is somehow compromised by turning down the master in the original 2nd/3rd gen set up when switching in the OD?

For me Doc, it was more keeping the control interaction like other Dumbles. I like to set it up in the familiar way. I think it sounded weird but I honestly can't remember exactly what it was.
Taylor, what value did you end up with on that resistor. Might be interesting to experiment in that area?
In the way the layout is wired IIRC, the clean master is switched out of the circuit when OD is engaged.
The standard wiring has it as a master for the whole amp.
I have mine wired the standard way, I'll post pics... But the issue I've had with these is that the balance between clean on OD is a little off, I think it has to do with the lower gain OD entrance.
Rog, I see you removed that. I did the same, but I put it back in. Overall resistance was about the same ~33k with either setup.
I knocked down the 1M/180k to ground to 470k/180k. I've been playing around with that value a ton, even as low as the solo 150k found in the skyliner, but it was a bit muddy.
I've been playing with pot values too, but put them all back to layout spec. I think I might go with the 500KA master. That seemed to work well

Taylor when you say the balance is off, do you mean the numbers don't "balance" - like mine on ODV 7 and M4. If I set them on 4 - no the OD would be too quiet. Or something else?

I figured it out...but basically the amount of clean signal I needed to push the lead channel was way louder than the OD when switching back to the clean channel.
I put an additional loop master on the back that helped big time
