tremolo mods: half/ full speed, hard/ soft depth.

[skiraly017]

I may not be paying full attention so please correct me if that's the case. It would seem we've solved the 1/2 speed and/or dual rate issue, but what about the hard/soft tremolo a la Fulltone? It's been awhile since I've played a Supa-Trem, but aren't there two distinct tremolo waveforms available in the pedal?

Please excuse earlier comment.

Grumpy day.

No, the hard soft switch on the Supa-Trem makes the Mix knob a heavier or less heavy "blend" by switching where the pulse part of the circuit is in relation to the output of the circuit.

What this needs is the voltage controlled up/down ramping LFO mod I mentioned in the questions about the Easyvibe. It works for tremolos too.

Half/double is trivial at any point in the speed dial.

I just did a design on the Easy Rotor Vibe, I guess I need to go do an EAsy Rotor Tremolo.

i have figured out, thanks to mostly skiraly, that for the 1/2 speed switch, i need to as a resistor in a switch that is half the value of the pot.

does anyone know if it's the same for the depth?  for instance, the depth pot for the tremolo is a 1 Meg pot.  would a 510k resistor be what i need for a good "hard/ soft" switch?  or should it be a lower (or higher) value?
