    What’s on *YOUR* workbench?

    Bean? More boards? Bigger boards that do sillier sounds? Welp, shut up and take my money and add it to the pile of "to build"

    What’s on *YOUR* workbench?

    Prepare to get weird. I got mine up and running on a DeadEndFx board (it’s sitting waiting for me to box it) after some trouble shooting. Thanks for reminding me to get cracking on that.

    Sparkly tone machines: Paragon, Closed Circuit Booster Limiter and 401K Compressor

    I award you 3/3 glitters. Curiosity - are you painting these enclosures glittery or do you have a glitter supplier?

    What pcbs are you getting for PedalPCB Black friday sale 2025?

    Look @jcpst with good taste. I have the electro vibe mini on order with the SMD XLR to see if it works with some preamps I’m building.

    What’s on *YOUR* workbench?

    I thought, THOUGHT, I was going to work on completing projects I have and cleaning up some weird issues I have in a couple pedals. BUT NO, I had to go and click the “Send Order” button. Here’s to more projects - Electrovibe mini and a XLR mini out (to see how it works for my projects).

    Tube Preamp PCB (draft)

    I did try the tube connections on the edge of the board, but it got kind of clunky. I like the idea of of the grid resistors off board, especially since it will just be for myself. And the parallel trace in that D3/R19 was a “I know it’s parallel but I can’t make the layout any prettier”...

    Tube Preamp PCB (draft)

    As my college football team was getting its teeth kicked in, I decided to work on this layout. Here's revision 3. I think, think there's at least 2mm between traces/holes. I used pads for the tone stack (I know, that part isn't pretty). I also moved the 275v to the top area of the board (with...

    What’s on *YOUR* workbench?

    I put some 0.1uF across U2/U3/U4 from V+ to GND. It has helped the LFO tick/bleed that happened with the “isolated” power supply I bought. It’s a pain to solder across the SMT chips, but it helped immensely. So, if you get an EffectsBakery vibe (or other pedal based on the Tri-vibe), the 0.1uF...

    Tube Preamp PCB (draft)

    Self reply. Man, I always screw up where ground loops would/would not be. I’ll give it a shot and have you tear it apart. :)

    Your best and worst pedal hot takes? 🔥

    I mean, it smells like coffee. But I just took a drink.

    Tube Preamp PCB (draft)

    I shouldn’t probably post when I’m a bit tired: I forget context. And yes, you’re right: the airwires are Ground connections. 1. I calculated 1.25 somehow, but I’ll probably move it to .75-.85, just to give myself a bit of leeway. 2. Good thoughts on the signal being smaller width. 3. The...

    Tube Preamp PCB (draft)

    So, I gave it another shot, this time in landscape. Little wider and narrower. Guess I went Hiwatt style. :) I did move some of the potentiometers from the bottom up a couple millimeters (my grid is in 1mm squares). Everything should have 1.5-2mm clearance, all HV is on 1.25mm traces, and I...

    What's in the mailbox? 📬 📦

    This showed up today. I needed a power supply and was thinking of building one. I can’t beat 8 “isolated?” outputs for $16+ tax. Only downside is you get the USB-C to USB cable, but you have to supply your own 5V/2A. Oh well, have plenty of those around

    Tube Preamp PCB (draft)

    Cool. I went ground pour on the bottom side trying to keep the big VDC on the top. No way I wanted to pour copper with those big traces. And you’re right, there are some big voltages there on the blue (bottom side). I’ll look at that - don’t know what I was thinking. The 1/16 (whatever that...

    High Voltage Hijinks

    With the classiness of these layouts, I need to see what you'd come up with the Trainwreck Express/Rocket

    Tube Preamp PCB (draft)

    Good evening - I like making perfboard layout of preamps, but I'm kind of nervous of the longevity of some of them (one is working, but the ground and +250VDC are literally millimeters apart!) . So, I've taken a shot at putting together a 125B sized (but no tubes!) layout for 2 tubes plus a...
