This is a library of perfboard and single-sided PCB effect layouts for guitar and bass. I'm not an electrical engineer by any stretch of the imagination, just a DIY'er who likes drawing layouts. It is meant for the hobbyist (so commercial use of any of these layout is not allowed without permission) and as a way to give back to the online DIY community.
Here's a 1590A candidate. The Kay T-1 Tremolo originally came in a plastic housing with a treadle that controlled the speed. Apparently similar to the Vox Repeat Percussion tremolo, but a little smoother.
Hello everyone, I ask you a question for those who have already built it, does it have a clean or saturated sound? . I built one, and it sounds undesirably medium overdrive, it's not nice, to make it sound clean I have to put it in the effects loop.
tried a couple of pots, b1m fits more than others, noticed that pedal signal is slightly overdriven and signal level from the pedal is more than from the amp, can you please advise something to do with this
Have the same problem here. I've try different low gain resistors and the result es sort of the same, the signal gets dirty. But the thing is that I tested the pedal with different amps with different size speakers and in one of them the signal was pretty clean, so that got me a bit confused.

ReplyDeleteDid you use this layout? The pedal in your video has 2 knobs. Did you add some mods?
Deletethis is the "O-Kay Tremolo"???
ReplyDeleteor not yet??!?!?!?!
This won't work until you add the 43k resistor from the base of Q1 to ground. 47k works for me but schematic show 43k
ReplyDeleteVerified, it works if you put a resistor at 43K as in the original circuit.

ReplyDeletebuilt it - nice pedal, have somebody any ideas of putting depth trim pot?
ReplyDeletehi, yes, replace the 68k resistor with a 100k potentiometer, you can experiment with 250k and up to 500k as you like
