Here is a new original design. I'm very happy with how this one turned out. :)
It's a very percussive tremolo based around the TDA7052A amplifier chip.

It continues with the idea I had when I designed the Black Current Vibrato, that two signals out of phase is summed together. One side is static while the other side is being modulated and filtered to leave some frequencies unaffected. This results in what sounds almost like a light phaser and vibrato'ish effect. So in a sense this is a continuation of the Black Current Vibrato (hence the play on words) but without the stutter mode and otherwise improved in every way; more neutral sounding, less noisy, more control, more versatile LFO and no ticking noise.

The controls are:
Rate - Controls the speed of the LFO
Range - Controls the range of freqencies effected by the modulation.
Attack switch - Sets the waveshape to hard (sawtooth) or soft (ramp).
I will post a video-demo later, but not until I have boxed this one using a fabbed PCB (just because it will be alot smaller and easier to fit inside a 1590B - the vero is verified and perfectly fine). So that might take a while.
