Hello all,
     Long story short I started collecting comic books again and a friend (old co working for the music store) of mine offered me some Spawn action figures. I said i'd build him a pedal of his choosing for them. He wanted a delay. One of my favorite (might just be my very favorite) builds is the Hamlet Delay but Jon Patton. His use of the charge pump to boost the signal before the chip is genius, It's one of the best sounding PT2399 delays out there, I recommend it to all who haven't built one. This time I used effectslayouts version. I love Jon's layout but i wanted the external tone pot. I also wired the volume as a trimmer and mounted it to the base plate via a piece of vero board and stand offs. I also did a "Slam" mod to it. This is a momentary switch with a 22k resistor soldered to the lugs 2 and 3 of the "Repeats" pot. What this mod does is a ramping oscillation. As long as your foot is depressing the switch it will continue to oscillate. It's a pretty easy / awesome mod. Anyways, here are a few pictures for you. I'll do a demo tonight and post it asap.







Thanks for looking!

I like how the etch came out, it looks like it was classy a long time ago :)

I didn't mean for the etch to come out "distressed" but I do like it. Thanks for the tip on the "slam" mod. I tested a bunch of different resistors and I think i actually ended up using a 20k not a 22k. it allowed for a little slower of a ramp.

I usually put an internal trimpot, that way I can dial it exactly how I want it.

Really awesome build, I also like the distressed etch look!! Your friend is gonna be so happy!

That's the first time i used the purple, I think I'll be using it more.

Nice one, Mike.  I'm also a big fan of purple pedals.
