Hey folks, thought I'd post here since it's kinda relevant to the forum and I've learned a good deal about dumble amps from here 9even though I'm no EE).
So I've been looking for a dumble clone for a while and after a lot of searching, I got chatting with Mark Roberts, one of the co-founders of Cause & Effects pedals and amp works. The company isn't around any more but I know they were pretty active here some years ago, building chassis, pedals and also d style amps (hardwired and PCB).
I met up with Mark a few weekends ago and ab'ed a couple of his amps (a handwired HRM 100w Bluesmaster and this #102) for nearly 2 hours and decided to go with his PCB #102 Dumble clone build. It was an almost instant, "there's the tone!" with that #102.
It had that smooth but still edgy OD channel that was instantly there and didn't need a whole lot of dialing in. Also, as a bonus, it has a couple of different reverbs built in. Including a Robben Ford inspired verb+delay setting that I've been enjoying (minimum delay + short verb). It also has a buffered effects loop.
Also, I bought the 1x12 from Mark as well. Has a really well broken in WGS ET65. Love the all black look!
I actually read through Mark's (and a few other people's) build logs. Really interesting!
Anyway, thought I'd share because mark used to post here fairly often. He also provided me with a manual he wrote for C&E amps and also the schematic. He was super helpful!

Very cool, congrats! Is the effects module built around a FV-1 DSP? Sure looks like it with what I assume is a socketed EEPROM .

Very exciting, please keep us updated! I have a C&E overdrive pedal...and I'm a #102 / Robben Ford obsessed fan. Is your amp something that this could be commissioned / build for others? Not that I have the money to purchase...but I can dream, lol.
Excited for you! Keep us in the loop...would love to hear clips if possible!
