First thing I noticed is that my custom footprint library imported flawlessly during setup. If the schematic drawing functions are actually substantially improved it would be a huge win.

My main thing is dead clean fretless bass and I have a DIY 500 watt amp and AudioKinesis cab that's as close to a reference grade FRFR rig as I can afford and/or have space to accommodate. That serves me well for acoustic instruments too. I use a little bit of room correction EQ on the amp and...

91% IPA and then Goo Gone for any sticky residue, if and when I bother.

AmplifyFun sends you a pre-production proof for approval, and is much more flexible on artwork submission format to boot. My bet is that if it works at Tayda it’ll work for Spencer.

Just as a FYI, this is the Github repository for my open source DIY EQ pedal project: https://github.com/Passinwind/PW3B-LPF But I’d start with the Ginsly board, it’ll be much much easier and probably all you need for your use case.

"Maybe there's just a DIY 3-band EQ stomp project out there you could show me, or maybe there's already a pretty good pedal out there that's exactly this." Yep, here's a recent addition: https://www.pedalpcb.com/product/pcb140/ Nothing wrong with your idea though, but without pics and other...

If you want to go amp free, why show us an amp? 😎 Please detail your actual desired signal chain. In general, if you need a line level output (0dBu or higher) it often pays to use a power supply voltage higher than 9V for your preamp/line driver. These days that is easily accomplished even...

I'll definitely check it out, and 5V power is super easy to come by these days, thanks. For my own pedal use cases battery power is mainly just an open mic thing for when I need quick and dirty EQ correction without messing with someone else's amp or FOF settings too much. Doing a more extensive...

Try an OPA1642 on an SMD adapter, if it'll fit. I've done quite a few acoustic instrument preamp builds over the last few years (for guitar, mando, Dojo, and upright bass) and IME that's been the sweet spot for a cost effective low noise choice.

I'm still playing catch up on optimizing for the OPA205 family in low current onboard preamp builds and battery powered pedals, and then using the small Traco power bricks for +/-15V power in pedals. But a headphone output for a new PEQ/Preamp/DI pedal is on my to-do list, so I'll definitely be...

I am highly biased, but by far my favorite is the resonant LPF section of this open source project: https://github.com/Passinwind/PW3B-LPF There's a different LPF board with a non-inverting front end that is primarily meant for onboard preamps, but works fine in pedals too. I plan to do a...

12V and 15v are both far more useful to me than 18V, since those are my typical optimization points for my self designed DIY stuff. I could've easily done something similar to your proposed solution, but decided to just buy a small Cioks and concentrate on PD negotiation for now. I bought a six...

I'm currently building up my first ever pedalboard and being able to run it off an embedded cheap power bank is a big part of the mission brief. And I've never liked typical barrel connectors all that much, but IME USB ones are even far worse reliability wise. So naturally I currently have...

I only built two completely new pedals this year, the rest were all re-dos in existing enclosures. Everything was of my own design as well, including PCB layouts. * HPF/One Band Parametric EQ/ Resonant LPF * Piezo/Magnetic Pickup Blender w/Resonant LPF for piezo side, effects loop for magnetic...

A simple two opamp section variable resonance high pass filter, to go along with the many successful low pass ones I've been doing for a decade or so. But it's been several years since my last attempt, and I do have some new twists in mind if and when I ever revisit.
