Already posted in the High Voltage thread, but my new tube bass amp has finally moved on to listening tests and "final" (heh) circuit tweaks. Still waiting on the bigger output transformer, although 60 watt mode is already fine for playing in my small jam space. Works well for acoustic guitar...

I never met a long plate 12AX7 I liked that much in gain stages, but I don't use 12AX7s in bass gear anyway, and would just use current production in a guitar amp build if I ever did another one and needed that much gain. The octals in my pic are 12SL7s, my first go with these. Finding nice...

Here’s the first rough take on my enclosure, not even bolted together all the way yet. The real one will probably have a lot more bling.

Tube rolling in my new DIY bass amp build: "NOS" tubes can be a real crapshoot, but so far so good...

Seems good so far, I think the EQ scheme complements my more normal active bass really well. On to the wacky one that’s optimized for slide bass with a “filter preamp” for the bridge pickup next. It’s working well enough that I’ll probably put together the rest of the case later today, and...

The guitar intro to Ripple by the Grateful Dead. Rock it before you box it. 42, of course.

Just about to have my first listen to my long delayed bass amp project. Only running in 60 watt mode for now until my new Heyboer 100watt OT arrives. Looked good on my test bench yesterday and I've already work up some new tone control tweaks I just thought of a few days ago. I just can't resist...

No new pics until the last few permanent parts arrive, but my tube bass amp is finally up and running beautifully on the test bench. Still waiting on the Heyboer 100 watt output transformer to be finished, but the power amp board has a two tube 60 watt option so I can just run that way with the...

I am still planning to release my one band PEQ/HPF that runs on +/-15V into my open source Github repository pretty soon. There will also be +/- 15V Baxandall EQ and resonant LPF boards to go with it, The LPF board is already vetted and the two band Bax board is in the build queue for hopefully...

Not sure what the tariff situation is this week (or tomorrow), but I'll look into it since I need to do a JLC3dp order soon. All those values are useful but I already have a ton of dual 100kC with switches on hand right now. I will be in touch, thanks. FWIW, I've been using 50k for Bax circuits...

Sure, just let me know if and when you're game to ship to the US again. Linear, or...?

Purple Slurpy w/Lilac Vein or vice versa, PPCB Special Edition. I'll buy five yesterday. I still have one pedal with the special edition Neutron Star finish kicking around that I just don't want to let go of, and I'd buy more if you ever offered it again.

Variable high pass filter for bass:

Working on designing 3D printed enclosures for my open source onboard preamp modules, which are going to be pretty cheap via JLCPCB. Probably time to take another stab at learning some CAD-fu, I reckon. These first proofs were just done with an online parameter configurator, which took like a...

If you can handle soldering relatively large format SMDs you can readily adapt the open source HPF board from here: https://github.com/Passinwind/PW3B-LPF/blob/main/V4%20Pedal%20Schematics%20and%20BOMs.md Or you can port that design to whatever format you may prefer. But I've already posted a...

If you can’t hear it, does it matter? ;) For starters you need an audio interface with a noise floor at least an order of magnitude better than your target for your builds. It’s trivially easy to acieve a signlal/noise ratio of 100dB or better for things like clean preamps, so your interface...

My scary fretless bass skills have always resulted in microtonality, and being a dildo comes naturally. Sign me up !

My old weirdo originals band used to double bill with a very theatrical band that I used to silently say that about all the time. But luckily both our audiences tended to like all of it, so it was still a really good fit.

I've been messing with 3 and 4 tap verb via the Cabintech digital BBD emulator chip for a while now, and once I get the second one built up I'll have stereo and/or eight tap options. But that chip is also way cool for glitchy stuff, and I'd love to see some other people here jump into designing...

Yeah, I'm definitely all for that. Not wild about the costume thing, but it worked for Sun Ra and countless other people I respected greatly, so carry on. Especially given the context of the YouTube/Tik Tok sort of culture the music biz has morphed into.
