Tubes!
Tube section consists of a typical (basically hi-fi) Alembic preamp and blended in with fixed ratio Diezel based high-gain preamp (see the schematic attached). Modifications were introduced during 4 years of testing with Warwick Thumb to get fat, dense sound on practice volumes with bare minimum of dials.
6SL7 have steel&timber smell and flat EQ, comparing to Tung-Sol 12AX7 V-shaped sound. It is possible to plug in 12AX7 via adapter. Tube choice is up to personal preferences of a player.
DSP
Digital part is based on Daisy Seed C++ DSP module.
OLED screen and true bypass added (I am still a tube sound purist!)
Compressor, Reverb and hidden Flanger mode were coded alongside with level meter.
Comparing to TC electronics I've found that the simpler the code the better it sounds. Definitely prefer Seed over TC.
I really do like Compressor and Reverb with pretty much gain on top....
Power Amp
- D-class poweramp by ICEpower ICE125ASX2 with two fans has a pleasant break-up sound and really, really cold!
I have tested 50ASX2 and found it also capable to deliver practice level volume (and still pretty cold). Thumbs up!
Generative design. 3D printing. A lot of it.
Yellow "bone chest" is designed in Fusion360, printed from Nylon with lasers (SLS) and painted (poorly). It is connecting two plastic trays (lithography, SLA). Front grill is filament print (FDM).
...better videos to come...

Lovely chassis design! I was expecting a totally tubular bass amp (preamp and power amp) but it's still a very interesting design. It's kinda strange to see the real deal long tail pair phase inverter in a hybrid amp, but recreating the design with tubes end to end would be a very easy task :). I'm a bit puzzled by the tone stacks and channel mixing here. Not a thing I was used to, but hey - it's always nice to broaden one's perspective :)
