Title: Any reason why this won't work? VHS/warped vinyl pedal
Post by: jonnygreentrees on February 03, 2017, 03:46:20 PM
Thinking about bunging a bunch of circuits in a big box and linking them together to get a warped record/Boards of Canada style effect.

My plan is one of these for pitch bending:

A couple of these for high and low cut:

And one of these for bit crushing:

Can anyone see any reasons why this won't work?

Thinking of doing high band eq > low band eq > bit crusher > vibrato

I would suggest using a vibe effect for the pitch bending. If you can get ahold of a duo vibe from the Function Fx fundraiser and build it with a blue LED, it will make a good vinyl imitation because it'll have a "bump" at one point in the rotation. Figure out how to set that to 33bpm and you're golden.

A full-on EQ is overkill for a high and low cut. Just work out the input and output caps and add a simple low-pass at one end of the other effects.

I'm also not sure what the bit crushing is for. It's not like tape or vinyl are low bitrate. Quite the opposite actually ...

Also check out the midfi clarinot. It does what you are looking for in the context of delay. And there are diy plans out there for it.

thanks for the replies.

I built the clarinot and it's not the effect I'm after. I'll check out that vibe though.

I get the caps would be easier but I would prefer the flexibility of the adjustable eq

Nice project! I love those kinds of projects.
A little while ago I built a Lo-fi machine that was a compressor (Mosfet comp by Circuit Salad) going into a Pitch Pirate clone (Mid-fi) going into a switchable Sonic Reducer (by Parasit Studios, absolutely beautiful bitcrusher, I very very strongly recommend it, you cannot be disappointed!)

Can't wait to see the result! Good luck with experimenting!! :)
