The final demo of the Dumble Overdrive Special #124.
Hopefully my playing won't put you off of enjoying the tone!

congrats for this personal realisation !
I REALLY like the different recipes that you choose for boost, brite, Jazz/Rock, OD , ... !!! ( in some amp , I don't like PAB or Brite or mid boost ... ... )
== not only that's the kind of sounds I'm looking for BUT it seems that most of the guitar's types can sound good on this amp !!!
So, really a big congrats !
... may be one day, I'll be able to build a such amp ... ( and anyway, I will keep these different videos, advices, ... )
Here I come again, after many years... I am about to build a D amp #124 with CLEAN ONLY preamp (only one ECC83 valve), low plate classic with 100k slope and 100k anode resistors etc. My goal is to make CLEAN sound only, with just a touch of ¨crunch¨ on higher gain - think sound of Peter Green, Mark Knopfler, Brian Setzer, and the great variety of Nasville Telecaster players (I play Telecaster guitar and Gretsch guitar). Some people call such amps nowadays ¨pedal friendly¨. Yes, I guess that seems right - although I do not use any boost, fuzz, sustain... pedals. I only use CALI76 compressor predal in front of the amp input, as far as the signal chain goes betwen Telecaster or Gretsch guitar that I play.
For tone stack it is really unclear to me what would be Treble, Mid, Bass pot values and tapers that are good for me. I was reading a lot these days here, and it seems that THE MORE I READ THE LESS I KNOW (actually, the less I am certain of what to make). Some poeple and some schematics and layots make it look that it is like this for those pots:
However, some seemingly knowledgeable member stated in some thread, that Treble pot is ¨a mixer¨ and that ¨it is good to be LINEAR (250kB)¨! It seems to me that it is right (?). Second, someone else stated that Mid with 250kA pot ¨adds mid boost¨, which in my opinion should be the role of Mid pot anyway. I also red that instead of 500kA for Bass it is OK to use 250kA pot (which seems OK to me - however, Ceriatone D-amps all have 500kA for the Bass pot, except one, named after famous guitar player, who uses 250kA pot for Bass, which looks good to me).
So, right now my idea of semi-final choice for this build is:
