On to v4 of my open source hybrid filter preamp pedal: It's actually meant for desktop duty rather than being an on the floor pedal, and the HPF function is always-on with the rest being bypassable via switch. The next one will use the switch for muting the whole pedal instead.

As a followup, out of the blue I found someone who's keen on doing through-hole PCB layouts for some of my designs and sharing them freely. I've built up five different standalone HPF versions recently and am just waiting on some new PCBs to show up in the next day or two to try a few more design swerves. Meanwhile, feature creep never sleeps:

As with so many things, it just takes a bit of practice and technique refinement and then the larger format SMT parts are not that big of a deal, IMO and IME. I've gotten my own SO-8 to Dip converter boards made up but thankfully I rarely need to use them these days. There are perfectly decent DIP opamps readily available, and if "close enough" is one's style that's that. I find no joy there, but I've been at this a very very long time and need a progressively bigger hit to justify even bothering by now. 😉

Nope, not really, and DIP format opamps are already mostly a legacy thing by now. But there are still decent enough DIP alternatives, just not true equivalents as I see it. I went with the biggest practical SMD resistor size, 1206, and the biggest of the common SMD opamp sizes, SOIC-8. The DIP-8 opamps I'd typically recommend are crazy expensive, and as with many others have pretty much gone missing for the last few years. Lots of people just blob solder SMD opamps and fix the bridging with solder braid, IME the main thing is just to use a small enough soldering iron tip. I'm nearly 70 and I can still do this stuff without using a magnifier, but I can certainly stil relate to wanting to keep it simple! But in any case, it's an open source design and I'd be more than happy to see someone take on a stripboard layout, it just won't be me. 😉

Yeah, although I very rarely trace anything or do overt clones I still find I end up reinventing the wheel with standard issue cookbook circuits quite a bit of the time.

Yes, all my open source projects provide a schematic and an easy way to buy printed circuit boards from a premier US vendor. In this case three boards would cost about $10 USD with shipping included to virtually anywhere in the world. I have no commercial involvement with that, I just share the PCB layout to the vendor's extensive free share list, the end user clicks "buy", and the boards ship about ten days later, typically. There's also a bill of materials on share at Mouser.com, again meant to speed up the ordering process considerably. I have friends in the UK and various other countries who may be able to help with parts sourcing over there, but this is just too much for me to take on myself at this point. Strip board is not a great option in this case because all the the preferred opamps are surface mount format. Additionally, I feel that if you want the DIY experience of using stripboard you might as well DIY the layout yourself too. And it would make more work on my side, because I don't use breadboards, stripboards, or anything else but PCBs very often at all, even for prototyping. But many of my friends in the DIY community want to build now, today. Nothing at all wrong with that, and as long as people properly credit the design source I have no objections to anything they do non- or semi-commercially. 😉 For the moment I'm using Talkbass as the repository for this stuff, but when I retire in a few months and move on to other things I will probably put it on Github or somewhere similar where I won't need to babysit it. Here's the TB link: https://www.talkbass.com/wiki/pw3b-lpf-open-source-onboard-preamp/ The new HPF design will be going live any day now, I'm just vetting a few options for use with other instruments by this point. Pedals are kind of a new diversion for me, so I welcome any and all input into what I can do to better help DIYers. This is the current format of the HPF board, which is probably going to be more or less the final version: BTW, I'm pretty sure there's at least one stripboard layout out there for the Fdeck v2, which is optimized more for upright bass and is "only" second order, but still works fine for bass guitar as well. Francis Deck posts schematics for many of his designs on his own website as well. Hope this helps!

Certainly true, but Josh Broughton at least used to contribute a lot of DIY oriented content over there.

Always on fixed frequency 4th order high pass filter prototype: Coming soon to my open source utility EFX library. Might have to reconfigure the PCB a little for a variable one in the 1590A box, but I'm sure that could be done. Fdeck told me he has a spiffy new one coming out soon as well, which will also be fully open source.

Making non commercial pedal clones for yourself shouldn't really matter a whit to anyone IMO. There's a huge DIY clone building culture these days, think a few heads would explode over this for instance: https://www.pedalpcb.com/product/pcb553/ ? 😉

Fdeck has a very cool new one coming out "soon." He told me it'll be open source eventually, but he's a busy guy and I have no idea how long it'll take for that to eventuate. In the past he's avoided shipping to Europe, FWIW. My new open source one is in final testing right now too, and I've been working on setting up a few builders in the UK and elsewhere across the pond to service those who can't or won't build their own. As usual, I have nothing to sell and no interest in going that direction myself. 😉 Also, I've seen postings in a few other forums saying Schallertechnik is no longer in business? Might want to grab the Vongs while they're still available...

I'd gladly pay at least $5K for the right upright -- if I had gigs lined up to pay that off in a year or less. OTOH, I doubt I'd spend even $100 on a new bass guitar of any kind at this time.

Interesting, I have have never seen that. Putting my BSX back in its stand takes about three seconds, it never was an issue at all in my case where in the very rare cases where I doubled bass changes always happened on a set break.

Country and Americana mean really different things here by now, I almost never see a real upright in country bands. The Johhny Cash-alike guy I used to gig with for a year or two with had an Epiphone Flying V 5 string at his place and would have loved for me to play it at shows. No problem at all with my Travis Bean or BSX EUB, or bass solos on several tunes a night. The Bluegrass Mafia were and still are a very different story though! 😉 As far as the WAV, fixed stands are a complete deal breaker for me, I just can't be anchored in one playing postion like that for any length of time without serious discomfort.

I hear this quite often, but not so much in my case, and I am in my 70th orbit. The Beatles might have been in my top 20 or 30 favorites at age 15, but by 18 I had had enough already.

Not just you. I've gone for a decade never listening to any rock music on purpose at one point, grown tired of favorites in many genres, and then eventually reset to just randomly enjoying random randomness, except when I don't.

EBS, for one. Not phantom though IIRC, rather a dedicated third conductor.

Right with you there on the rest, but no scratch plate or other plastic bits on anything ever please.

That would depend a good bit on how they spec their frequency response curves. Is 10K the peak, the 3dB down point, or the mid point at full boost? And what is the peaking frequency at 1/4 boost, the most many of us would probably use? And then the other end of the graph might be more important to many of us, where do we start hearing that control acting? I personally don't want to hear a lot of/any 1K just from boosting my treble control, but a +3dB point well below that is not uncommon in some popular designs. I've built good sounding EQs for bass that peak at 30KHz and others that peak at 3K, as @Sparky Marksays the bandwidth matters a lot too. 😉

I remember that story Paul. The old Fender cabs get no love from me, certrianly. And I've always loved tubes for guitar but rarely all that much for bass. That's just for my own playing though, not for others. I've heard all kinds of gear I don't like playing through work great for others, wouldn't have it any other way really. 😉

My tastes are notoriously out there, but the B-15 is easily my least favorite bass amp ever, go figure. When I sold mine I ported to unamplified upright bass for as time because I thought all bass amps were that lame. I'd take a Bassman 50 any day over that, at least it would be nice for guitar. But with the right mods and a modern speaker it could be a lot nicer for low volume bass for sure.

Most I've ever owned is right now, 4 basses and one guitar. Looking to cut that down though.

Other way, near Hood River OR on the WA side of the Columbia River.

It's a pretty wacky sounding widget as well, I definitely enjoyed mine.

Not an issue for me obviously, but there's a very good chance they'll be offering their own version of my latest design on their website sooner than later.
