hi guys!

i have built modularkomplex's LF398 based rate reducer today (from page 3 of this topic).
i have one issue here. there's a very audible cv, almost as loud as the audio signal. when i turn the pot the pitch of the noise goes all the way up/down.
the effect itself works fine on the audio signal (edit: at least seems so).
i played bass through it and could turn the rate down (1M pot) so much that it sounded detuned (edit: with the cv i guess) and got pitch modulated. but i must have made a mistake so the cv comes through...

any idea what i could have done wrong here?
thanks!

Hello everybody, my first post Very Happy

I have been reading this forum for quite a while, a great level of expertise here, good stuff!
I have been thinking about building a bugcrusher-like-device for some time so i thought it would be a good idea to bump this thread to ask for any updates, schematics and the like. I would prefer a LF398 based device because of better availability.
Thanks a lot for any input!
Greetings,
Nils

Many moons after this thread initially appeared..

Today I'm publishing a new project version WorkshopCrusher in kit form.

Kits go on sale tomorrow via thonk: http://www.thonk.co.uk/shop/bugbrand-workshopcrusher/

And I'm also holding 2 workshops this weekend in Manchester:

Full build docs (inc. schematics) are now online:

[the no-AD781 approach may be of particular interest given how this thread started..]

Hopefully interesting, useful, enjoyable for some of you!

Cheers, Tom
