This is not your amateur tremolo pedal. Volume control, check; no worries that your volume drops when you turn on the pedal. Depth control, check; the depth goes to zero, complete silence, sweet. Rate control, check; rate ranges from 4 seconds (15bpm, measure with metronome, 4 seconds) into ringmod territory (inaudibly fast, i'll guess 1000bpm). The usable range of the knob is really good too. At jam yesterday I was comfortable fiddling from 10:00-3:00.
But i'm taking those three knobs for granted, this is the ULTIMATE Tremolessence ...
Things start getting interesting with the tone shaping options. Being able to change the duty cycle of the triangle and square waves can give you a huge pallet of wave shapes (ramp up, ramp down, pulses). Those wave shapes combined with the treble knob makes this the most versatile analog tremolo I've ever played or read about. This power in tremolo voicing is really something that puts others to shame. Too many other tremolo pedals only give you a single sweet voice, or give you no voice leaving the sound flat and symmetrical (you can shape your tone to be very dry if that is something that you do want). I've always like the voicing options with the RedWitch pentavocal, but the Tremolessence just really blows that away. I guess I just really like being in control and having the options.
so that's the beef of it imho. I don't know why it's taken me so long to get one of these little guys (yeah, they weren't on the market yet).
Oh! and there's the HOLD feature that's gonna make all future pedals designed seem archaic if they don't start using this great option on all designs. It sure beats having to use an expression pedal to fade in your effect (yeah you can do that too with this gem, and it works completely as expected... hahahahaah).
ryans got his bases covered.
i'm satiated.
by next week I'll have more to say
and i'll have fiddled more with the expression control and stereo funzies also packed in.

now posting as Forrrest.
