Evil tremolo, or Slicer?

[akhagen]

I'm looking (and has been for some time) for a schematic for a tremolo effect that is just plain on/off, no waves what so ever. I've heard about something called Slicer which exist in some multi effects, but I want a stomp.

I want it to be on/off like using the PU-switch of a Les Paul, but much faster. And as simple as possible, just Rate-control. I've tried some tremolos with "Square"-options, or chop-switches, but they are still too soft!

I am useless in this area, so I need a full schematic or nothing at all... I truly believe this is the place to ask, so: HELP!!!

look for variable stuttering pedal on geofex.com

I found the pedal on Geofex. It is rellly intresseting, but it seems rather complex, for somehing that I, beeing an amatour, find fairly simple. The layout is refered to on several places on the Internet, but to my knowledge, noone has yet built it...

Any other ideas? Apart from the Stutter-pedal, I'm looking to build a Kay Tremolo, which is suppodesly quite percussive in its sound.

Thanks for the tip!

And best wishes from the north / Dan

Well, maybe. It has an input buffer to make the innards independent of the external conditions, a switch to do the switching, an output buffer to drive the output, and that LFO to tell it when to switch. You could delete the input and output buffers, maybe, if you were sure your setup would not need buffers.

I guess it depends on how good your survey of DIYers is. There have been a couple of folks with questions on building it that post here, so there is at least one. There are clicking problems if you are not careful about building, but that's going to be true of any switching setup.


You could use a CMOS analog switch, but a JFET is much easier to de-click.

Shunt switching to ground is usually quieter than series switching.
