Just straight ahead chug! Layout from dirtboxlayouts. After I built it I got curious about mods and got a breadboard going. Then lost interest. Haha. I have some notes but need to revisit that project and see if i can't easily mod this build. The art is a beer label I peeled off the can. It came...

This guy has been on the bench for months and months. In part because I'm indecisive but mostly because I was way out of my comfort zone. It has been a great project to learn and get into new territory. I first started with the DBA Sound Saw. I liked the idea of it but wanted to make it suit...

Here is a custom Muff. Started as a green russian and evolved into whatever it is now. :) Fairly flat eq, a little thicker all around, nice sweep across the gain control. Sustain and Tone are swapped from their traditional places because...well...I wasn't paying attention and there isn't much to...

Love the Broadcast. Best drive, all time. Added a trimmer to bring in more bass, from stock to very full. It's set closer to stock. I also added a toggle to for a low pass at the end of the signal to trim off some of those piercing highs. It came out sounding great and some mojo with the germ.

Where is a good place to see a dual pt2399 circuit? I would like to try it but googling for schematics left me overwhelmed. Seems like a handful of circuits that most people cant get to work and some swear by. Thanks.

The Catalinbread Heliotrope is notoriously noisy. However I have one on a breadboard (with a handful of mods I will list) and its really very quite. I added a Jfet buffer to the front and it kills the little bit of noise even further. Now, enter the stripboard build which whines like a mother...

I bought H11f1's from digikey (x10 purchased) and mouser (x10 purchased). I ran the test on them per the helpful Chuck D Bones (https://forum.pedalpcb.com/threads/pandoras-box-fizzle.25875/post-329869). I'm looking for an approximate range of 320mv to 2.5v. What I get is 1.8v to 7.1v. I tested...

I have been working on a dual filter pedal. Something very out of my wheelhouse. I liked one channel of the DBA Sound Saw so I started learning about notch filters to create a second channel I liked. The circuit needed some more volume and I wanted to stay with the reverse beta theme the circuit...

https://dirtboxlayouts.blogspot.com/2019/08/death-by-audio-redblue-card-fuzz.html?m=1 Just for poops and giggles I was wondering if I could remove the fuzz and just hear the filter and resonance controls. I messed with it enough to know I dont know how. 😀 Removing the diodes and changing...

Cross posting from: https://www.diystompboxes.com/smfforum/index.php?topic=133885.0 Has anyone had success with this schematic? https://static1.squarespace.com/static/56a5a0e242f55268768a0c2b/t/592ad16c15d5db2bc1ba0439/1495978348902/steiner+parker+vcf.png The comments on the layout over at...

Looking for a little advice. I breadboarded this and like it quite a bit. So I drew the schematic out so someone could actually read it. I went ahead and fixed the pots so it was "correct". I also added power filtering and a PDR at Input. Couple of problems: The Filter switch makes a popping...

BEHOLD! The OVERLOADER! Just a big muff that was tweaked and tweaked until it was great. Then I started experimenting with a way to blow it out more effectively than a boost in front. I put a Bass Boost in between clipping stages with a blend. Gain and Overload(Bass Blend) are very interactive...

Hi all. As much as i love Electric Wizard i just don't play like them. Suffice to say the board has been sitting in a pile of never getting boxed things so i started to tinker. Here is the final product and it finally got boxed and everything...

Traced my original and modded for longer delays. The filtering on this one is pretty unique so the longer repeats dont get much chip noise. I put in soft switching for the surge switch too. For some reason the high gloss clear coat came out suuuuuper high gloss.

I am very proud of how this modded Rat (NO DUH) came out. Some value changes and a Filth control that blends between LED and Asymetric Si clipping. There is a lot of texture to play with here since the LEDs are never symmetrical unless all the way counter clockwise. I specifically wanted to...

I want to put a dpdt switch into a pedal with a soft switch. It only needs to he engaged while pushed in. The relays i bought are for 4.5v but only engage with 5v. Go figure. So I stole 5v from the L7805>run to momentary switch>positive of coil. Also an led I may include but it's not needed...

I have a project in the works that needs a dpdt momentary switch. Its so hard to find one that doesn't have a very hard press so I would like to go soft touch. I saw this and would just rather build my own into my layout. https://mas-effects.com/digital-relay-switch.pdf Im curious too now if...

There is a mostly complete report on this over in the mods section but here are the bullet points. The art is taken off a beer from There Does Not Exist. Art by @ibayarifins. Great beer, Great art. Mode switch changed to pot Octave blend added to remove octave completely at full ccw Bigger...

Great sounding pedal. My 10 year old populated and soldered about 90% of this. Graphic is a drawing into Ai and then photoshop.

This is where my hyper fuzz is so far. I'm particularly interested in knowing if I can improve upon the octave blend. It works well though so maybe against all odds i did good. Gain changed to A250k for MORE GAIN. The Boost is skipped over so Scooped and Full can be wired to a B50k blend pot...
