First build prep, "King of Tone" clone, importance of diode selection?

I have had a lot of fun recently fixing and modding some old Ibanez 9 series pedals. I ordered PCBs for a treble booster and a king of tone from Aion FX. I've been studying the build guides and adding parts to my cart on amplified parts.

The only thing I can't find on that site is the right diodes. They don't have BAS33 or any of the substitutes. Can I use a 1N914 in place of a BAS33?

Also, for the treble booster (Aion FX Naga Viper clone), is it worth getting a variety of different transistors to test? Thanks!

Distortion Circuit Issues

I'm attempting to design a simple-ish distortion pedal with a single hard clipped gain stage, custom EQ tone stake into a buffer but I'm not having much success. I feel like Im missing something obvious here. Power at opamp and the biasing reads correctly and I have sound on the first op amp only, nothing on the output of the whole circuit so it gets lost somewhere around the tonestack or maybe before. The sound coming out of the first opamp has some gain but its not effected by the gain knob moving and the clipping led I have in place of the 1n314 isnt lighting up so I think theres issue all round tbh. Have I got the inversion wrong here, any ideas? Cheers! I feel like its something obvious but am snow blind currently.

Whats the difference between mosfet and jfet distortion?

I wanted to do a plexi like pedal, and looked for the wampler plexidrive but the j201 seemed pretty expensive actually, so then i seen the box of rock which is like the same but with mosfets, but i don't know what is different with the 2n7000

Zonk - Reeves Electro Zo

I built Marcus’s Leo last year and really enjoyed the process of it. This time I’ve had a crack at his Zo after seeing a layout on dirtbox layouts. I find the point to point layouts very enjoyable to build and this was no exception. I breadboarded a few transistors first but other than that, it’s true to the schematic on dirtbox.

It’s quite a versatile fuzz and can go from roaring fuzz to almost overdrive tones, with some glitchiness in between. As is my process with every pedal I build, I covered serve the servants by Nirvana using the pedal on both guitars and using different settings on both before basically maxing it out on the solo (2:14 if any interest).

Harmonic Percolator Build - Low Output Volume

Hi all, I decided to build my first pedal, a HP build kit by Analog Noir. After much debugging and back and forth I decided to seek some help here. The output volume with the pedal on and the knobs at Max is lower than my clean guitar signal. I went back and inspected everything and could not find anything that stood out. Wanted to check if someone would have any pointers on what I should look for or anything that stands out on my eyelet board setup?

Thanks all in advance! Excited to join this community for the first time instead of just being a lurker for so long.

HORUS

Just in time for the spooky season!

Brought to life by vintage ICs, awakes from long slumber. It's a CHORUS with a silent "C"!

I'm really glad it's finally alive. Took a while but I think it was worth it.

Thanks to u/indefinite_o who made original schematic. And to a u/the_bad_cosmonaut for those incredible sand knobs.

Schematic Help: Making tone controls work in reverse

Hi! I’m trying to make these tone controls response in reverse of how they normally do. How do I do this?

Currently:
TREBLE: clockwise turn (less treble -> more treble)
MID: clockwise turn (less mids -> more mids)
BASS: clockwise turn (less bass -> more bass)

What I’d like:
TREBLE: clockwise turn (more treble -> less treble)
MID: clockwise turn (more mids -> less mids)
BASS: clockwise turn (more bass -> less bass)

Edit: I would like to avoid using C-Type pots if I can, because they’re difficult to source compared to A and B-type.

Why do I want to do this? Aesthetically, it would work better for a pedal I’m working on to have the controls act this way

Any help on this is greatly appreciated. Thanks!

Overall Pedal Design: Top or Side input/output jacks?

I recently saw a post in r/basspedals where someone had their pedal board set up entirely with pedals that use top mounted input jacks. Each pedal side by side looked so clean!

I've been designing my first pedal from the ground up for the last few months and my original enclosure design was your traditional side input/output jacks. Now I'm considering top jacks because of the potential for such a clean pedalboard layout.

Any thoughts on the DIY community about top vs side?

Take 2

Hey all, ElectroJunk Pedals is officially back.

Long story short, the first time I tried being a small pedal company I got really burnt out trying to do way too much and force this to grow way too fast. It became overwhelming and it just felt like another job. I decided to close the company and quit building pedals.

I closed shop last March, and didn’t touch anything pedal related for months…. But as many of you here know well,it’s hard to step away from building pedals. I got pulled back in (thanks r/diypedals 😄) and decided to take another stab at this.

So, EJP is back with three pedals and a new look.

Thanks to everyone in the community and all the great posts that got me hooked again!

Question about potentiometers with center detente

I'm building a PedalPCB Box and All EQ. The bass, treble, and mid potentiometers on the "real" pedal have a center detente. I haven't been able to find a single gang potentiometer for the treble control that has a detente (B250K).

Will a regular B250K pot function identically so that the treble is flat when the knob is at noon, just without the haptic click?

Octave fuzzes or normal fuzzes for drone/doom without integrated circuits (IC)?

Im looking to build a really high gain fuzz without having to use the integrated circuits (my store doesnt have them anymore lol) so im kinda attached to do other circuits xD. Im looking towards a sunn O))) gain style pedal if possible: im not looking towards an specific sound bc im in a band that makes original music so doesnt matter.

I have (for luck) germanium transistors in my house so im able to do fuzzes of germanium too :)

What would you call this?

This is the circuit I posted yesterday. Basically it’s a buffer feeding a fuzz style circuit. Idk if you would call this fuzz still or distortion.

I’m gonna deconstruct this breadboard and build something new so I thought I’d capture and share what it actually sounds like.
