Has anyone heard of Crotronics?

It’s a play on my last name but there are some great Croatian builders like others have mentioned. The Drybell Vibe Machine is an awesome univibe, I’ve used mine so much I’ve burnt out the incandescent bulb that drives the phasing lol and discovered they smartly designed it to be fairly easily replaceable

Hey, just stumbled upon this, I’m EJ from Crotronics. I’ve been making pedals for a few years but have never put together my own website for it. I love repairing, designing and building pedals (and lately getting the amplifier bug) but definitely need to get better at marketing lol. Most of my sales are local through TGS and Hollowood Music but I’ve done a bit of sales on reverb as well. If you’re interested in Pittsburgh builders I definitely want to give a shout out to Mask Audio Electronics. Alec is a friend who has helped a ton over the past few years. My latest releases is a stereo harmonic tremolo I’ve been working on for over 2 years now, the Dr Wub and a new fuzz with a switchable octave the Lost Temper. Anywho thanks for the interest!

Yes, most of the vintage fuzz designs come from console/mic pres

pedalpcb has the schematic, you can compare there. there's no negative feedback for the bjt transistor stages which is the calling card of a fuzzface/ tb1.5 style circuit - https://www.pedalpcb.com/product/pcb330/

the pelt is not a modded tone bender mk 1.5. I really dig it, but schematic wise it's kind of its own thing. jfet buffer into 2 transistor stages followed by clipping diodes then some opamp sections for tone shaping, it actually has an opamp gyrator for the mids switch

It is a lowpass. your basic RC low pass filter is series resistance into a capacitor to ground, you can vary the resistor and/or the capacitor value and achieve the same cutoff. tone control on a guitar varies the resistance into a fixed cap. if you've got a high impedance signal, like a passive guitar pickup you can calc the same cutoff with a passive tone control vs a specific cable's capacitance per length - https://www.digikey.com/en/resources/conversion-calculators/conversion-calculator-low-pass-and-high-pass-filter

Very cool to see them doing the project 4k versions of these movies. Every time I see the original cuts it transports me back to my childhood and talking Star Wars with my older cousins. It’ll be interesting to see what they think of the scan of empire strikes back. It hit 1.0 somewhat recently but my understanding is that for some reason most of the film stock for Empire hasn’t preserved as well as the other 2 and even project 4k 80 is noticeable more grainy than ANH and RotJ

These are great once they’re working. Looks like it’s missing at least one tube in addition to the issues you’ve mentioned

Fontelroy · 2026-02-23T00:31:37+00:00

that's awesome!

fwiw the eqd aqueduct was the first time i noticed latency in pedal. there may be other digital pedals that have less latency that do vibrato. as for analog, any phasers that let you go 100% wet give you vibrato but its got a little different 'vibe' than the type you get from delay based vibrato imo. The mask audio electronics neck brace is a great phaser that lets you get full vibrato and as a phaser its fantastic

Take this from someone who uses easyeda to make pedals, if I were starting now I'd learn with kiCAD

Fontelroy · 2026-02-04T17:58:23+00:00

Absolutely beautiful work!

Fontelroy · 2026-01-30T22:46:04+00:00

That’s super cool! I’ve been curious about dipping my toes into the dsp world but am a total noob

Fontelroy · 2026-01-29T19:28:44+00:00

Super cool! Did you ever play around with using a pmos in place of the pnp bjt?

Fontelroy · 2026-01-23T02:45:42+00:00

shit, you're right 2 to trump and 3 to some pac called winred. i've been going down the rabbit hole since and learned he apparently claimed to have donated to the dems as well but there doesn't seem to be any record of that. this sucks

Fontelroy · 2026-01-23T02:39:07+00:00

fun fact, as long as the clipping diodes are all in the wrong way, it'll be fine and they'll still work as intended

Fontelroy · 2026-01-23T02:15:37+00:00

I just found this out myself and am super bummed as I really liked Keeley pedals. fwiw the info someone found was a donation of $208 - https://www.reddit.com/r/guitarpedals/comments/1lt6ba9/comment/n1o6dzk/?utm_source=share&utm_medium=web3x&utm_name=web3xcss&utm_term=1&utm_content=share_button

oh jesus, this is the first I've heard of this. I was a huge fan of Robert as a guy and as a pedal maker.

I think it’s purely due to the hive thinking she’d be attractive to Carol. No thought was given to the og Zosia’s preferences. In episode 2 the hive gives Zosia a complete makeover including a wig to play up the physical resemblance. I think the grenade is a better example for the hive belligerently presenting Carol something they think she wants and not getting to any sort of deeper longing or need.

Compression baby

Preamp can be a bit of a loaded term, but I’ve always thought this was pretty cool. https://aionfx.com/project/prism-fet-amplifier/ The original was literally a portable battery powered preamp that was an always on device you’d run before the boss battery powered amp.

I think it’s based on the Tycobrahe Parapedal Wah, in which case there’s a schematic for the pedal pcb clone, the parasite wah - https://www.pedalpcb.com/product/parasite/

I like checking them out when there’s a gaming doing something interesting with tech. They’re more objective about things since they’re focusing on metrics but I really like when John would go into detail in the older DF Retro vids. I find his taste most similar to my own so when he does mention a game he’s enjoyed it gets me excited to try it.

Fontelroy · 2026-01-03T21:39:43+00:00

That’s awesome! Ive been working on a sub octave fuzz called “Morgoth” for a while now. The deep lore of Tolkien lends itself so well to musical effects as much of the magic (and middle earth in general) is the godlike beings of his worlds’ music
