My first little project!

A stereo feedback delay network reverb, there's alot more that can be done with this..

Sorry about the clutter of wires, i'm not the most organised of people

Have fun, and let me know what you think!

NICE ONE sambean !!!!

Sounds fine, and diferent from the rest. very good job

Anyway i've found something to comment:

Changing the vaulue of the small knob ( the one under reverb time) usually produces some kind of ritmic patterns in the reverb, . I suspect that, as you multiply the value of this knobs by delays lengths, the delays will no more be mutually prime, so some kind of pattern appears

A nice thing to add is a very low frequency low pass filter ( freq around 0.0008 or so) to kill that nasty clicks on low frequencies.

Also a soft damper ( LPF) between moduels 8LPF and hadamart matrix coudl help to soften more the final sound. Only guessing here, don't know the theory behind this.

Ooh, this is interesting! Downloading now!

@Nas, I wish I wasn't so damn obsessive with things like ordering my schematics - takes me an age to finish something as I spend half my time 'tidying' it :wink:

Hey guys

Thanks for the welcome!

Hope you can find a use for it, it's pretty much based on the FDN reverbs from JOS's website, the delay length calculator was just rustled up quickly and so may be causing 'beats' in the reverb tail..

I've added a simple 0Db gain bandpass RBJ filter as an EQ, this should also get rid of the DC in the feedback.. The lowpass filter in the feedback has been fixed also (was meant to be feedback..)

here it is..

nifty reverb
One recommendation though, when EQ FREQ is all the way to the left, it does nasty stuff to my speakers. Maybe prevent it from going all the way (to 0 I assume)?
