This one has been in the works for a long time. I love the 1776 Effects Multiplex. Just a stellar echo sound with a cool momentary warp/detune feature. The Jr. model has modulation, which really adds a lot, but it doesn't have the momentary button. I wanted both. So step one was a Multiplex with the supplemental modulation PCB, but then I had another idea… momentary oscillation.

There are a few ways to do this, but after asking around, I decided to go with my original idea, which was to use a momentary 3PDT switch where the common row was wired to the feedback control on the PCB, the normally connected row was wired to the feedback pot, and the momentary row connected to a trimpot of the same value, set just at the edge of oscillation. With a little help from Morgan (see the linked thread), I got it all working as expected.

So now I have a Multiplex with modulation, detune, and oscillation. Throw in a decal design from my talented designer from Dave, and we're good to go…

…except that I seem entirely incapable of building a Multiplex without mis-drilling a hole. My original location for the output jack was not compatible with my placement of the PCB. So I have a little bit of a silly I/O situation going on, but oh well.

I haven't pulled this image out in a while, but this looks like a pretty appropriate occasion to do so...

Very nice to see what's in your mind become reality. Well done!

I am so thoroughly impressed by this!!! The neatness of the work, the look of the enclosure, and the awesomeness of the mod you added!

I am starting to work on this project myself now.

I am debating on adding reverb to it as well to make it like the Multiplex Deluxe.

Nice job, looks sharp!

Thanks guys. Since my last photo I have decided that the internal trimpot for setting oscillation doesn’t work great for this pedal, due to the oscillation point being different for each of the echo types. So I mounted it externally on the side. Works great, but unfortunately makes this pedal even more of a pedalboard hog.

It looks great, did you silkscreen the enclosure?

Great job through and through.

Thanks! Powder coat from Mammoth and a water slide decal.
