This time I tried to build the multiplex delay in a smaller box.
I etched the PCB and had to solder some components on the copper side, but it fits nicely. I even used another board for the pots.
For the switching I used a dpdt to have the series/parallel modes, without the single delay mode.
The sound is nice, the parallel configuration gives a nice echo effect, but as for other delays, it gets dirty at longer times. At some settings the oscillation from the repeats sounds like a shimmering effect, but it also can get really weird.

I made a reverse etch for this one

Wow. :o Looks like you used about 95% of the volume available inside that 159A!
Do you have any special buffering going on for the parallel mode, or are you just the front of each circuit?
That's .... tight..... as.....
Amazing!
:o These 1590A builds are getting ridiculous, I have enough problems stuffing things into a 1590B! Awesome work!
I got your 1590A right here...
Damned impressive work here.
Ruddy hell. What's next, a Tau Pipe in a 1590A? :) :)
That is an unbelievable amount of through hole parts in a tiny space. And it's a beautiful pedal. You really do amazing work. I'd love to see this hooked up to a submini tube amp.
Wow, that's nuts. Can't imagine stuffing all that in there :o
Really clean etch too!
Omg. Pretty impressive, well done 8)
Thanks guys!
The parallel mode is, as in the multiplex, just the signal going to both inputs and added at at one side of the mix potentiometer.
That is amazing! :o
Damn Thomas! Amazing work.
A not so short video to show that it works and how it sounds! In case you were wondering...
Watch out for the oscillation, it's loud.
The schematic I used was this one:
