New Experimental Workshop Delay

[knutolai]

Hey!

Back with a new version of my experimental workshop delay. These will be built at workshops in Bergen, Oslo and Trondheim (Norway) this fall.

There are parameters for Volume, Mix, Delay Time, Feedback and Selfmodulation. True millennium-style bypass and an extra momentary footswitch to max out the feedback. It's in the same vane as the EKKO posted below, though the repeats are a little darker:

.zip file with BOM, schematic, wiring diagram and GERBER file for PCB manufacturing.

Schematic:


If anyone is interested I have a few PCBs to spare. Just send a PM!

Mods:
-To alter the tone of the repeats try modifying R14 & C15, as well as the Multiple Feedback Filter on PT2399 pins 15 & 16.
-For a more conventional delay time range swap the TIME1 pot with a B50k pot.

Thanks for posting More disintegrating fun to play with!

Thanks! I've breadboarded it, and it works great!

Glad you like it!

Hi
I made a vero (my first big layout) on tagboardeffects. http://guitar-fx-layouts.42897.x6.nabble.com/file/n35706/ExpDelayPladask.jpg;cid=1486133702305-151
It is verified as working. I first had some problems with a bad regulator. I use now a modulation pot of B100K and feedback of B50K.

Was looking through this thread and the last link is broken...is there a stripboard version somewhere?

[stringsthings]

The stripboard version is over at tagboard.   It's in the forum section.
Go to "Contributions", "Verified Layouts", "Delay, Reverb".
For some reason, I couldn't link to it directly, but it's easy to find.

Thanks! I didn't know about that section of the site - some kind of unreferenced javascript or something...can't link to directly but very cool.
