Dude, I love it! Maybe you can shed some light on my question about the Clip knob?

"Can anyone tell me about the Clip knob? I feel like the middle range of travel it changes eq or emphasis or something."

The best answer is don’t touch the clip knob

FANTASTICO!

TransBoost v2.0

The intensity of clipping and transformer-saturation is switchable.

Any sound samples or comparisons?

Schematic with the mods?

 

[disssa]

I used no new schematics. Only known schematics of this thread.

It's a long shot, but does anyone have a Transboost that they would be willing to part with? I never should have parted with mine...

 

[D.M.N.]

Old thread, I know, but figured I'd throw this thought out there. There's plenty of pedals imitating amp pres (Catalinbread DLS, RAH, WIIO, a few different Runoffgroove, etc), and I worked up some circuits for JFET implementations of Sunn amps (200s, 2000s, Coliseum PA), but most I've seen don't seem to have anything to replicate the output stage. Might be interesting to pair the Transboost with some of those pedals outright, or blend the circuits together, to provide the preamp and some output stage 'emulation' to AIAB pedals. Then pop in a balanced XLR out...

Also, on R19 and R20, where they can be jumpered for harder clipping, it looks like @disssa put them on a switch, could also possibly put them on a dual gang pot to vary that. Haven't built it so it may be too subtle to justify a pot, but a thought anyhow.
