The Standout seems very cool. At least in theory it really should just tighten the amp in a transparent way.
I think it’s a clean boost (no mid hump or added EQ, just boosts the level of the incoming signal) but with adjustable high and low pass filters?
That way you can push amp’s input if you want, but also use the high pass cut the sub-low end that is making the amp seem loose (and cut some hairy/fizzy high end too with the low pass).
So it’s not like an overdrive pedal that imposes it’s own EQ and cuts low end because of capacitors and what not in the OD circuit block the low end from getting through.
