    What's a buffer, how do they work and why would we want one?

    Thanks for this thread - found it after thinking about buffers

    What's on the workbench?

    I have no idea what this pedal actually is, but have seen it around and it's the best name for a pedal I've seen in a long time! It can be a passive volume attenuatator with a LED on off inside for all I care, but great name

    Skeptical buffer build (a bassist’s build report)

    cheers! :) figured it was fine but confused me when it wasn't working to begin with

    Skeptical buffer build (a bassist’s build report)

    Question for @Robert ... I was getting +17.7 and - 17.7v from the power ... which makes sense to me based on the spec of the power chip (9v doubled, minus the voltage drop over the diodes) But the build doc say +-15v - which I can't see how it would do? Not complaining as an extra 5.4v...

    Professional vs amateur-ish in PCB design

    As a professional graphic designer who spends my working life doing graphic design, I can confirm reducing it down to “contrast” is an amateur approach 🤷

    Skeptical buffer build (a bassist’s build report)

    Marked as 4 star “good” because there really is a limit to how excited you can get with a buffer!

    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...

    What's on the workbench?

    Quick scan says over 740 pcb listed - and when you’ve done that you get onto the secret big boss PCB … and then it’s game over. Completed the game and you’re ready for death, pass on your 750+ little boxes to your bewildered kids and find out what happens in the afterlife, or get eaten by worms...

    oh don't worry, I'm kept well away from it

    Professional vs amateur-ish in PCB design

    oh no there's enough experts it's complex enough product you couldn't do it without - it's just Putin's war managed to delay us from when the gov said we needed it deployed

    Professional vs amateur-ish in PCB design

    I was talking to one of the guys at work about something we're developing. There's a component that has to be kept between 4.9 and 5.1v - and if it detects fluctuations it bricks itself and has to go back to the manufacturer for a reset. This is a good security feature. Then the 240v - 5v...

    Warwick Hellborg preamp transformer question

    I know AML as they are fairly local to me. And seen CAPI - the challenge will be getting them to the same/similar values as the hellborg ones Alternative I guess would be a non-inductor based semi parametric mid control

    Warwick Hellborg preamp transformer question

    I’ve got the basic circuit into KiCad now to build it as a preamp… Thanks to @vigilante398 I know that a neve style line input transformer will get me in the ballpark - so carnhill or cheaper OEP equivalent Output Di transformer is from the output of a 5532 stage - and I should be able to...

    Skeptical buffer introduces noise when harmonics switch engaged

    I was going to ask, did you get the polarity right on those tant caps?

    Relay Bypass – do I really need one?

    Though with a relay in the right place the audio path can be made shorter. One of the oddest things about pedal design is running the signal the whole length of the pedal twice from the jacks to the footswitch
