My layout is weird?

Anywho, so it was pretty simple to change the full-tone to the demeter, eh? That layout was based heavily on the actual board layout in the Supa-Trem...

sorry, it was a good layout, it just lacked a few labels to tell what certain solder pads went to, which way to put in the vactrol, and the blend pot was wired in wrong resulting in no tremolo sound. I went nuts though and put all kinds of labeling all over it, I guess I like to do that. thanks for the layout by the way, I used yours over two other options I had

yeah it was a very straightforward modification... just omit one capacitor (no trace modifications) and go through and trace the rest of the circuit and put in the Demeter values part by part. I was surprised at how many differences there were in part values, given that the sound ends up being quite similar between the two. I like having the volume trim pot from the Fulltone, even though I just leave it on full anyway.

The only thing wrong with the blend pot wiring on the layout is that I didn't note that blend lug 2 also connects as effect output. Otherwise, I've built that layout as is, so I can guarantee you aside from that note that it works as indicated.

really? I thought 1 and 3 and 2 of that pot at least two were going to the wrong place. maybe it was something else in my build that caused the hiccup when I was also changing that part of the build. if you built it and it worked i guess that speaks for itself

[monkeyxx]

here's my build... the guts aren't worth seeing. I added the hard/soft switch from the Fulltone, it's pretty subtle, but there is a difference. It's a little smoother than other hard chop tremolo sounds I've heard

Can somebody compare Bajamans Trembulator to the original Tremulator? Maybe make a soundsample?

There's a new version with some useful additions:

I'd really like to see the schematic.

This is a different pedal than the V1, it should get its own thread -- if there is any info
