    Found me some relays …(stupid question number 6765)

    So in our village there’s this social enterprise place where leftovers from local industrial stuff gets sold - lots of half rolls of fabric, Perspex with some bits cut out, offcuts of leather and so on - it’s great. Today I went down and got £1 bought me a whole strip (50) of Borns 10k...

    Stupid question number 245: bipolar power

    So I’ve built a load of pedals, Mutron clone, Aion’s L4 preamp PPCBs skeptical buffer who have used bipolar power supply’s. Most others use a monopolar power supply (if that’s what it’s called) +9v and gnd with the vref being fed into the input … I get that bipolar power supply is how older op...

    stupid question about Tayda/PPCB drilling....

    quick question that's possibly so obvious that I've missed something... Tayda's PPCB drill templates are all listed as "sold out" - why? when do they become available?

    Skeptical buffer build (a bassist’s build report)

    here’s an odd one, a bloody buffer, who needs a buffer? Well a while back I helped a mate build a PPCB frequency interchange filter, and trying it at the start of my signal chain - even with the filters turned to have as little effect as possible it seemed to make a big change to my pedalboard...

    Adding effects loop into pedal and avoiding ground loops…

    I’ve searched, I’ve googled and lots of things about isolated power come up… If I wanted to add a switchable send return loop to a pedal design… presume buffer on send and return to avoid any impedance issues - is transformer isolation needed to avoid ground loops? Thinking of combing an input...

    Old transistor radio for parts? 📻

    Years back I was at art school and one of my sculptures was a radio mast - made of 2x2 about 5m high with branches tied on it to disguise it as a tree… at the bottom was a 1950s Sony transistor radio on a platform, and a vintage bike wheel with rope around it and a handle - if you spun the...

    LED lights and charge pump issues... asking here as struggling

    So asking here as it's full of people with knowledge.... and this is a problem I had 3 years ago and sold the pedal... then bought it back.... I have a pedal board. It sounds good. Power comes from a Cioks DC7 - with isolated supplies, included grounds isolated from one another. The DC7 plugs...

    Warwick Hellborg preamp transformer question

    My favourite preamp ever is a Warwick Hellborg one - they made it for a short time and a silly price ... then blew them out cheap at Thomann and I hesitated and missed out... the thing is the magic was in the first preamp stage - I could turn the DI off and it would still sound great... From...

    Any suggestions where to get an enclosure like this? I'm guessing custom made but thought I would ask the collective hive mind!

    Understanding Lab Series' L4 (L5) Fender style tonestack

    Hello I built @aion 's wonderful L4 preamp - channel 1 has a fender style tone stack - but it's missing the capacitor between the treble and bass going to the R6 that a fender tone stack would have.... I've stuck it in TSC and what I put in for the fender tone stack and what it shows is kinda...

    protecting enclosure printing...

    Going to get a few enclosures printed, Gorva M45 in matt black, printed in black - any tips to keep the finish protected while I drill them? Obviously clean up the metal filings as I go, but wrap them in something? there's something obvious here I can\'t think of

    MN3207 - what to use it for?

    I don't build masses, and tend to buy kits from Musikding ... so my parts drawer isn't massively extensive. Howveer I do have a MN3207 which I notice isn't a cheap IC - Think it was left over from over ordering for my low tide mini... what should I build to put it in? (also relevant, bass...

    Gorva m45 with top jacks - yay or nay?

    I want to build a prunes and custard/curds and whey - but no bigger than 1590b - PedalPCB pcb is a little too wide for 1590b :( so looks like I’ll be doing my own Which got me looking at the smaller gorva m45 - which I know can be done with all top jacks - just is it a good idea too?!

    Aion Lumitron (MuTron iii) - with some mods - a bass player solders

    So I got a kit from Musikding and it all went together super quickly! It’s the Lumitron design of a Mutron 3 which was just super simple build - the sister board for the 3pdt footswitch is a bit different to the ppcb approach but makes sense I guess… While they make them nice and easy to build...

    MXR bass octave deluxe randomness

    I picked up a secondhand broken pedal kit off someone, and he chucked in a faulty mxr bass overdrive deluxe for free. Basically the thing doesn’t seem to be filtering the signal going into the detector- so there’s a constant noise coming out when the bass is plugged in but muted. Roll off the...

    Am I mad? (Moog pedal based question)

    I was looking at the schematics for the Moog MF-101 last night and opened KiCad to start building a version in there... Is this a fools errand to even be thinking about? Should I just get that clone with the pirate on the front? help

    Has anyone tried Z-DSP cards plugged into a PedalPCB project?

    I was looking at some Reverb pedals, and realised the Neunaber pedals I liked were built on FV1 So started looking at some other reverbs and found some nice sounding things on the Z-DSP platform.... I then saw on some modular synth forum where they had decoded the pins on the cards to use in...

    SOLVED Compressor indicator LED noisy turn on…

    Right, so this might be a common problem but it’s impossible to google… I built Aions trace of the L4 preamp https://aionfx.com/app/files/docs/l4_bass_preamp_documentation.pdf It has a LED indicator that the limiter circuit is limiting. It switches on a bit late (ie well into limiting) but...
