I finished up a pedal that I’m pretty excited about. It's a FV-1 implementation of the Mad Professor Deep Blue Delay, where the FV-1 handles the delay time and modulation, but the filtering is analog circuitry around the FV-1. The DBD clone was the first build I attempted, first try (on vero)...

Hi, just to make sure, the Basic Relay Bypass (Latching) build docs say to use 78L09. But, I thought 78L09 was supposed to have a minimum 11V input. Is it the case that it still functions fine, just with an output slightly below 9V if we input 9V?

I’m planning to mod a rockman bass headphone amp to accept typical 9v power (the guy lost the original special +/-6V power adapter, and he lost the battery cover so batteries aren’t an easy solution). I drew up a circuit for converting the 9VDC to +6V/0V/-6V DC for the rockman. Anyone see any...

For me this is a great medium rock drive, especially pushed by a Klon type circuit for just a little more heat and mids, but it’s great on its own also. 2 Mods: 1. 50kA on the tone pot makes it much better sweep. Volume could stand to be log pot also, but I didn’t change it. 2. I put a 3way...

Built went smoothly, plenty loud, and the phase switch is a nice feature. In my opinion, it needs the Unicab before it to sound good, and I prefer to add a little room type reverb. It sounds nice with my lighter drives, I wasn't too fond of it with high gain sounds though, but it could have...

I'm sure many of you know this, but it's a new trick for me today. I had the thought, and found some other info online which helped me bring it to life. An arduino connected to a computer can be a quick and dirty O-Scope! You can send data to the computer through "serial print" commands, and...

Has anyone used the new Tayda lines/shapes customs drill tool to make slot for linear pot yet? They say minimum hole is 3mm, I’m wondering if that’s their smallest bit? And, will the ends of the slot be rounded according to the bit diameter? Wondering if I should use the lines tool to make a...

This is a gift build for a friend who helped me with a video project. He’s into playing metal and has mentioned interest in both the 33 and Grind pedals before. I don’t always post my builds but this one had a few finishing touches that I found interesting so I thought I’d share. Sorry, I forgot...

After discussion on another thread, I'm sharing some code I developed for a functional tap tempo delay using the FV-1. This could be built using either pedalpcb Arachnid or Pythagorus pcbs with some circuit mods (attached schematics). Read the Intro comments of the code for knob functions...

I had this copper enclosure from a re-house I'd done for somebody, and had been curious to try out the plumes circuit. The flat-top LED is from https://lighthouseleds.com. 2 simple mods I did which I'd recommend. -100kA instead of 100kB for the volume pot. I had the B in there originally...

I wish I was cool enough to make this enclosure. This pedal belonged to my neighbor as a kliche build that he’d bought on reverb. It was not working, and he was more interested in having me make a klon similar to my own build’s look and mods, so we did that. I’m sure the kliche could have been...

Just built this from a Fuzzdog pcb. Pretty cool project. The vibrato mode is impressive for such a low parts count. Very cool to read up on RoG site about the design process. The phaser mode (swirl) is cool, though sounds thin to me with my tele. The whirl mode is probably my favorite on this...

Fairly straight ahead build of a big muff Using the values for green Russian. I only used the aion pcb because I prefer 1590B with side jacks. Initially I had planned on using mid knob which the aion pcb accommodates. But, after messing around in the “tsc in the web” calculator for quite a...

Built this for a friend. Very cool pedal, still deciding what we’ll do for the art. The enclosure is sparkle green left over from an old mammoth order. This is my first experience with uni vibe sounding circuits, so I can’t compare, but lots of range available especially by adjusting the two...

Not sure if this is trouble shooting or if this is normal operation. I finished my photon vibe build and have been experimenting with TR2 and TR3. It seems very temperamental. There are many settings where there is a strong clicking sound and the signal even cuts out. So if I adjust one trimmer...

I had my own pcb fabbed for measuring jfets Vp and Idss. I find it extremely convenient compared to setting it up on breadboard, or even a vero build, since I have board mounted DC jack and toggle switch (Vp / Idss switch), and some instructions printed on the board. I the circuit from here...

Built this as a commissioned request for a diamond bass comp. I found this pcb from lectric-fx made to fit in 1590B. I referenced the fsb diamond bass comp thread to find the value changes to make it like the bass version. The toggle switch on the side the is tilt EQ frequency (900/250Hz), dpdt...

Made this pale green compressor circuit from the tagboard layout. Sounds great, though a little bit “clicky” when the comp is turned up. This may have to do some with the led/ldr combo. Anyway, I added an attack knob described on the fsb thread, which is similar to how the EQD Warden is...

Built this from the vero layout here. http://vulcanofx.blogspot.com/2014/09/chopped-boss-oc-2.html Sounds awesome, really enjoying it. Compared it with my friends Boss OC-2 that I'm borrowing and it sounds comparable (minus the 2 Oct knob on the Boss). It is a pretty involved vero build (lot...

Pretty wild sounding, lots of fun. I put a SHO boost circuit on vero in there because with my tele it seems to track a bit better with some extra volume on the input. But too much and it gets really noisy/glitchy. Would probably work best with a noise gate before, but I don't have one of...
