From the post

It's been a while but I saw this little one was missing, and as I own the pedal and like it, I think it's a worthwhile addition. So thought I'd try to get back into the game even if it's a bit diddy and embarrassing compared to what the other guys are posting :o)

Info about the original:

Like the Rust Driver, the HAO Sole Pressure was designed to recreate the classic sounds of one of the most desirable guitar amps in history – in this case, the legendary ’59 Tweed Bassman 4x10 combo. The HAO Sole Pressure contains carefully selected components that allow the user to dial in the smooth, creamy overdrive of this classic amp, right down to the characteristic low-end sag unique to the combo version. Dual knobs control Output and Drive levels while three switchable EQ curves offer plentiful tonal options without compromising your guitar sound. This dual control configuration also allows to the Sole Pressure to act as a semi-clean booster to coax more character out of your amp. If you’re looking for the classic Fender amp tone that defined a generation, the HAO Sole Pressure will let you achieve it with any guitar and amp in any playing situation, without the hassles of owning vintage gear.
