Tremolo?

A friend wants me to build him a standard meat’n’potatoes tremolo, but I don’t really see any ‘standard’ offerings (aside from FV-1 stuff). I think the Woodpecker or something like the Mesmerizer might be too much fun for him. Haha
Anyway, it would be nice to have something like the Boss TR-2 or VooDooLabs Tremolo, etc.: Something with control of the depth, rate, and the wave shape, and optionally the gain.
 
the 1776 cardinal tremolo sounds pretty great. I built mine with a spdt on-on switch (harmonic and normal tremolo, no bright mode). Switch could be omitted and a jumper used to only have normal tremolo mode, but I find the harmonic to be really nice.

I will say it’s a little trickier than most builds on here. The documentation is extensive and has information on biasing the jfets and leds with the trimmers.

Woodpecker isn’t so fancy. The issue on the woodpecker is sourcing the 2n6027. A lot of fakes out there. Get the one from mouser

Yes, 2N6027 are not available at Tayda and I was bitten by eBay malfunction copies. Grrr.

In the end, I screwed the PCB itself changing and testing many 2N6027. It was my second build and my only failure (12 success/13) so far.

I'll be posting a straightforward standard tremolo and harmonic tremolo soon. No mojo parts, no JFETs, everything common and readily available.

Howdy! Any update on these straightforward trems?

I’ve done two veroboard EA tremolos in the last few months, would love if the next one was a nice and simple PedalPCB build instead haha

the Bajaman trembulator is a good option. There is a version of it (Madbean Double Flush). It would only need to include having a waveform control.
 
Yep, from top to bottom: Rate indicator, LDR driver, Active/Bypass

I'll have a reverse sawtooth tremolo (similar sound to the Hummingbird) soon that uses all common components and does have a rate indicator LED.
 
Harmonic tremolo.... ? I'm up for that. What circuit would we be looking at.... suspense....!
