DEMO MB Degenerator- Delay with Envelope Driven Modulation

[KR Sound]

This one sounded interesting so I figured I’d give it a go. It’s a 2399-based delay with a ‘Bloom’ control that can add a half-step down repeat depending on how hard you play or some extra color to the echos. This is going to a friend of mine for getting me an awesome deal on my Twin.

Here’s the text from the documentation:

“The Dengenerator was created with envelope driven modulation in mind. The delay circuit itself is pretty straight-forward and the real fun is in modulating that delay with picking dynamics. A simple “sound to light” style circuit was utilized via an LM386N-3. This lights up an LED in proportion to the input amplitude. The brightness of this LED controls a light dependent resistor which runs parallel to the “stopper resistor” of the delay control. I chose this over modulating the entirety of the delay range to keep the modulation subtle and controlled. However, you can get some neat pitch bending when the Bloom control is cranked. Additionally, there are two clipping diodes in the repeat path to clamp self-oscillation so the volume doesn’t get out of control. It has the added benefit of adding a bit of “tape saturation” effect at high repeat settings.”

I'd love to hear this

I’ll make a video of it later today.

Here’s a few minutes of screwing around. I start with the Bloom off then turn it half way up and then all the way.

Thanks @homebrewtj that's really cool

Thanks @homebrewtj that's really cool

I’m sure it does cooler stuff than I can make. “I’m just the bass player” and recently picked the guitar back up after a looong time.
