Passinwind

There are at least a few other options but finding them on OSH is a real challenge. Someone on Talkbass already did a nice looking SMT layout that I'm pretty sure he shared, I'll see if I can find it. Several years ago I did a through-hole one meant for modern parts, which was maybe my very first attempt at doing PCB layouts. Came out fine in any case. And then I have a fairly standard Baxandall based two band board about to go on share in the next few days, as part of this project: https://www.talkbass.com/threads/the-passinwind-open-source-preamp.1259692/#post-19535550 . The two band module works great as a standalone thing, and can be configured for Bass/Treble or Bass/Mids as needed. To be clear, I don't sell any hardware, and my stuff is targeted for relatively self sufficient DIY'ers.

Inexpensive bare PCBs for MM2B clones and/or near clones are quite readily available from other sources, FWIW.

You can play it that way, "underhand" with a slide, with banjo picks, a flat pick, or plain old fingerpicking: There's a piezo pickup on the resonator, broken out to a stereo jack with the humbucker on the other hot contact. Has a bit of a 12 string guitar vibe when playing chords, and can be surprisingly mellow and quiet when that's the player's intention. I play a weekly house jam that has way too many bass players, and many tunes I've been playing for decades, so this has been a great diversion so far.

Primarily meant for my banjo-dobro hybrid, but still works well for bass too:

A particularly insidious example: https://www.talkbass.com/threads/caution-regarding-some-newly-introduced-speakon-cables.1617450/

A tuner for myself, then whatever the guitar player could use. Oh wait, a fantasy desert island? No guitar player then! 😉

True, and dials also don't crackle, but potentiometers sometimes do.

It can radically cut job shop assembly time and costs these days, even in pretty small build quantities. And most of my favorite opamps are SMD-only, which played a big part in my moving to more and more SMD parts in my DIY builds starting several years ago.

Use them pretty much anywhere a generic FET dual opamp like TL072 is called.

It sounds great amped up with my DIY bass slide bars. I didn't know much about Gold Tone, but they turn out to have some pretty well known endorsers and to be a bit bigger company than I expected. They make lots of lap steels and resonator guitars as well: https://goldtonemusicgroup.com/goldtone/products/guitars?menu_category=round-neck-resonator-guitar,slide,square-neck-resonator&sort=az

Not strictly a lap steel, although I do plan to use it that way quite a bit: There's a contact pickup on the resonator as well, with a stereo output jack to allow outboard blending or a two amp setup. It sounds closer to a dobro than a banjo, but definitely has its own thing going on.

Fretted bass is the Debbil's Work, let him play it if he so chooses.

Sometimes re-tuning the kick and/or the floor tom a little can help as well, in my experience.

Short answer: put it in medium to wide bandwidth mode with some boost, sweep frequency until is makes things worse, narrow the bandwidth as needed, go to cut mode rather than boost and fine tune the frequency. An experienced user can do all that in a couple of seconds. A really experienced user just dials in the primary problem frequency that they already recognize and cuts it. Another possibility is playing with cab placement, for instance getting it out of a corner or closer to or further from a wall or the floor. It may also be worthwhile to make sure it's not related to unwanted bass getting into the microphones and/or exciting the drum kit and creating ringing that way.

Yes indeed. I used a DSP board from MiniDSP that included programmable EQ capabilities as well.

Zero, for coming up on 6 years now, and I'm fine with that. When I was gigging the answer was almost always one, and that's all I even owned for couple of decades. In about 40 years of gigging I only used a fretted bass all of twice, IIRC.

Ouch! Heal up fast. And this kind of work takes however long it takes. 😉

And a different color shifting enclosure from Cusack/Stompbox Parts for this one: That enclosure came via a group buy, but the vendor says they may make it a regular option since it sold so well.

FWIW, I finally got around to installing a second DIY filter in my 5 string Marco Bass, so it's now one per pickup rather than one inline with standard bass and mid controls. I tuned the neck pickup filter considerably differently than the bridge one, after doing a new bridge pickup tuning as well. My simple mixing scheme works really well and this whole thing is now back on track to be part of my open source project series. I'll post details on Github soon, but I have two hybrid filter pedal designs to wrap up first. My goal is to have a loose builder network built up worldwide for those who don't want to or can't roll their own, but keeping it primarily DIY is my strong preference. Great to see all these new takes popping up. I'll post a few clips when I can con one of my pro player friends into helping out, no one wants to listen to me playing a fretted bass! 😎

And the new econo one, using through-hole parts all sourced from Tayda, and a very inexpensive Tayda case in a pre-drilled standard format they do for various Pedal PCB effects, which they also printed for me: ......................................... Compared to the one pictured directly above, this would take a hobby DIY builder maybe 1/4 of the build time. Once it's well tested all the details will be available here: https://github.com/Passinwind/PW3B-LPF

Just yet another hybrid filter preamp build:

I haven't done up a Spice model of this yet, as I have a lot of customer work going on at the moment. Thanks for the heads-up!

Nice to see you on here! And all of that sounds pretty familiar...😎

I can take a stab at doing a better one later, but at least it's mostly readable now.

Putting it in a photo editor and inverting black and white via an edge detection algorithm made it quite a bit easier to read, FWIW.
