Tools, Tones and Toys for Guitarists
Here’s EQD’s take on PT2399 delay. The most unique thing about it probably the use of a Big Muff-like tone stack. It will definitely fit best in a 125B with the board mounted pots, but if you use long leg board mounted pots and populate them from the component side it should fit in a … Read more
Had a sleepless night, so I decided to knockout some new layouts before the end of the new year. This one kicked my ass a bit, but I got it as small as I could. a nice sounding delay, that’s similar in architecture to the Deep Blue Delay. It’s a nice sounding warm, natural delay. … Read more
Don’t know much about this one. Stumbled across it on the Tagboard forum and thought it was an interesting design. It can apparently do normal delays as well as some lofi craziness. Schematic and discussion here. Laid it out for board mounted pots to fit in a 125B.
Gotten a lot of requests for this one. I’ve put it off because the schematic that’s out there isn’t exactly straight forward, not to mention it’s 7 pots, 2 switches, 3 ICs… You get the idea. Anyway, I wanted to keep this 1590BB friendly, so all the pots are board mounted… except one (Blend). Six … Read more
Continuing with the board-mounted (almost) everything theme, here’s what I call the Switchback Delay. It’s my take on the Deep Blue Delay with a few modifications. More info in the build doc linked below. Switchback Delay Build Doc
Here’s Valve Wizard’s take on the PT2399 delay. It’s very similar to most PT2399 delays out there, with a dual op-amp providing input and output buffering. This was designed with the tails function and it uses Valve Wizard’s usual J112 switching. Here’s his original schematic and explanation of the circuit. You can also use a … Read more
Here is a verified layout for a quite unknown slapback-echo EH pedal. You can find the original FSB thread here. I’ve added an output boost to cover volume loss. I’ve found only one video around but didn’t sound great.
Here is the newer version of the Cave Dweller. You can find Brian’s original project here.

Here’s a really nice delay designed by Nocentelli. You can find the original thread on FSB here. This is his description of the circuit: Here’s a variation on the deep blue delay; two PT2399 chips and a current mirror delay pot give around 2200ms delay, although beyond 700ms gets pretty lo-fi. There are two points … Read more
