I was thinking about a potential mod to this circuit, where the Scooped and Full paths could arrive at a pot for blending, rather than at a switch for toggling. Would it work the way I am imagining if the Scooped path went R26 to lug 3 of a pot, Full went R27 to lug 1, and lug 2 connected to...

Recently I've been messing around with the HM2 circuit and throwing around different design ideas. During that process, I've noticed that the stock of common SMD JFETs is seriously dwindling in the usual places I look. I know someone somewhere will have a stash of them - getting my hands on a...

Hi folks, I'm sure someone here can point me in the right direction. I'm designing an effect for someone that has both a boost and an octave up. I'd like to have a toggle that allows switching between 3 modes: boost, octave and octave into boost. I tried to work this out with a diagram of a...

It's probably time I admit I'm obsessed with the Mach 1 circuit. I have built a number of my own versions of it and have even been designing a distortion pedal based on it. Today I decided to actually build my Mach 1 board and am pleased with the outcome. The enclosure is a bit of an...

After a few months of being crazy busy with work and family, it's been nice to get on the tools again and work on some projects just before Christmas. I love the Greer overdrive circuits and have built a few different versions combining the Mach 1 and Southern Belle schematics from this...

I built a crazy bass pedal for a work colleague's band earlier this year and it has been working for them until recently. It has a fuzz, boost and filter inside it, all living on separate circuit boards. You can see more about it if you are interested on this page: Bass fuzz/filter It has been...

Hi folks, I have decided to build my kids a practice amp for Christmas seeing as they have started playing recently. So far the plan is to use Erik Vincent's 10 Minute Amp circuit (7W class A-B power amp) and a Belton brick reverb like the Boing. I just need a Fendery clean preamp as the front...

A friend of mine has asked me to build him a BE-OD, but he wants a boost after it to give him 10-15% more for solos etc. I'd prefer single knob and not too much colouration, so which boost would you suggest? It's going on its own footswitch after the BE-OD circuit. Thanks for your wisdom 🙏

I built a Precision Drive clone (brewed my own PCB) for a friend. He likes it but is wondering if it should have more output volume. I did notice the output volume was lower than I expected, but the pedal still made my amp sims chug so I assumed it was working correctly. Does anyone have...

One of my favourite circuits is the Mach 1/Southern Belle, which I have enjoyed building and messing around with. I'm trying to understand how parts of the circuit work, with an eye to potential mods. Below is the first section common to both circuits, taken from the SB build docs: I think I...

Does anyone know of a good source of raw guitar DI tracks, preferably free and fair use? I'm making a few of my own to use for quick audio demos of new pedal builds, but would like to source some that represent other styles of playing, or use guitar sounds that I can't really get from my...

I'm playing around with the Six String Stinger circuit at the moment, planning out a few potential mods. Having learned this week that this OD/boost pedal has absolutely nothing to do with a very clean high headroom boutique tube amplifier - which is obvious on reflection🤦‍♂️ - and is instead...

Happy Easter folks! I had some free time on Easter Sunday, so I got out the Six String Stinger board I've been waiting to put together. The build went fairly smoothly, although I need to get more solid core hook-up wire or some pre-tinned stranded, as the stranded I was using was annoying and...

Inspired by @JamieJ and others on here rolling their own PCBs, I thought it would be fun to have a place on the forum where people share the cool stuff they're working on in Diptrace. Other PCB programs are more than welcome, I would love to see what circuits you're cooking up and how you're...

I love my Nobleman a lot, but the bass can sometimes be overpowering in my setup and I wanted to try and make my own version with control over the bass. What I've ended up with is something between the Nobleman and an Aion Andromeda, with a couple of differing component choices. The PCB and...

I know this isn't a breadboarding topic, but this part of the forum seems to be the place where cool DIY stuff ferments. 😎 Essentially I want to incorporate MIDI controlled on/off switching into a standard relay bypass setup. It should be possible using the existing ATTINY/Arduino MIDI...

I've been shamed into posting this through reading the All In Good Fun thread 😅 I have been stepping up my pedal skills into designing my own PCBs in DipTrace (speaking of good fun!) and recently completed a build I've been wanting to do for ages. This two-channel overdrive has a Lightspeed...

I've been messing around with both the Mach1 and SB schematics in DipTrace and having lots of fun with them. Great circuits. You can see how the designer built the later pedal from the earlier architecture. The Southern Belle can get pretty gainy for an OD and sounds good like that. What would...

Help me out folks. I am looking for Tayda alternatives for buying knobs. Particularly Boss or MXR style knobs in multiple sizes, and also anything aluminium, are what I'm interested in. I found some great knobs at BLMS but shipping was going to cost >$80 AUD (I've ordered from there previously...

Hi folks, I'm in between projects as I wait for parts to arrive, so I'm thinking through another project on my list. I'm a teacher at a high school. The students at my school who play guitar are all talented but are also limited by lack of quality effects. They have generic school amps (Fender...
