ttv42-68-33-1.png I'll start off with a little background.
I don't know much about electronics.
I soldered my 1st circuit about 3 months ago but have immersed myself in schematics and breadboards the whole time.
Also I'm probably the only person out there that is breadboarding and testing with a single coil lap steel and a cheap karaoke speaker.
So that said any and all feedback and analysis with different setups is greatly appreciated.

I started with a Bazz Fuzz and cascaded between decades...

Since lockdown had me working from home all spring/summer, I spent about 6 months working on this project. It uses four PT2399 chips in parallel, synchronizes delay time using the four PWM outputs of an ATTiny841, has tap tempo, and the usual suspects of individual toggles for playback and feedback for each of the four heads . The swell control simply turns on all delay stages for playback, and the drift control changes the ratio of the delay times for the repeats (I should change the default...

Since I was having so much fun playing around with PT2399's this summer, I also thought it would be fun to do a DIY reverb pedal that didn't use a Belton brick or FV-1. I know designs with those are plentiful and common, but I'm a cheapskate and didn't want to spend around $20 for a single component. Instead, I designed this pedal with 4 PT2399's and controls for size, mix, dwell, and a mode switch. The mode switch is subtle, and has a slightly different effect depending on the setting of the...

Hi I want to build a vibrato, I have some mn3207 and mn3102, does anyone have any design or schematic?

a preamp i built to directly record guitar into my Digital Audio Workstation
I dont like the free vst plugins, so this was an alternative to micing up a guitar amp
You could also use it straight into a power amp
I modified our guitarist's little Marshall MG30FX and added a line in 1/4 jack. The amp had a 1/8 line in for a MP3 player, but i added the extra input so he could still use the effects on his amp when using this preamp.
One other mod i did to this little amp was to add an extra 4700uF...

I found some pt2399 in my component box and I want to build a delay but there are many models on the net and I would like to know which one is the best in terms of clarity (I know that the pt2399 is already a bit noisy) but I would like to know Any recommendation

This is my take on the original 1978 DS-1 schematic where I've fixed issues of that awesome pedal to be great in a modern rig:

- The first transistor gain stage has control for amplification level. It gives you an option to adjust your instrument's level with high output pickups, prevent the effect from fuzziness , and get more variations of a drive.
- Mid scoop is moved from ~500Hz in original DS-1 to a more pleasant 700Hz.
- Has added mids control to pass from scooped to boosted mid...

Hi folks
Here is a little overdrive / distortion pedal I knocked up on veroboard earlier this evening. Based on a modified Boss DS-1 with an active high and low tone control section - sounds really nice and simple to build. I may get some boards fabricated if sufficient interest in building it, in the meantime here is the schematic and picture of the finished verified pedal.
cheers

It has been a long while since I posted any new projects - my apologies, sometimes life gets in the way ;-)
Anyway here is a little project that can easily be installed in your guitar and is extremely miserly with regards to current drain, so your battery should last for at least a year - probably longer!
If the battery goes flat during a gig, no need to worry just switch the preamp /buffer off and you are back to stock passive wiring in your guitar.
The idea for this little project came from...

Guys.

I have at my disposal a lot of AC127s so I decided to make a negative ground version of the fuzz factory

Here is the schematic

Please check if everything is okay and I hadn't made any mistakes...

The idea for this pedal was that I had some low gain AC128 transistors (~27 & 60 hfe) laying around, why not try and come up with a germanium overdrive. I watched a JHS video about stacking pedals and a That Pedal Show video about hitting a overdrive pedal with a rangemaster (to mimic a rangemaster going into a cranked amp) then put this together. So it's starts with a more full range rangemaster into a germanium ce amp then a lpb-1/ce amp to add volume after those first two stages. I like it...

Hi

I've been working on this idea for a while, trying different designs to mix together an overdrive and clean signal using a dual gang pot.
It started life as a modified DS-1/Big Muff hybrid, which I couldn't get to work so I went with this. It's an electra distortion and parallel common emitter stage with big muff tone stage and another CE stage on the output.

Sorry not sure why I can't get it to embed the video.
