And it's working faster than a very fast thing

Not sure what happened to my YouTube link so I'll try again here.

Hey guys. I'm the author of a book "Electronics for Guitarists" that's been out for a few years and I recently started a YouTube channel related to the book. So far I've posted a lot of tutorials on basic circuit theory and transistor circuit analysis, I'm planning to post a lot of content covering effect design, vacuum tube amp design etc. It's pretty detailed and there's no fluff or subjective opinions. Down and dirty analog circuit analysis and design. If anyone is interested in checking it out (and hopefully subscribing), here's the link. Thanks!!

> output B has noticeably more output/ gain than output A

They are the same circuit on the same signal. One of the output stages IC2_A or IC2_B has to be wrong. What's different?

Never mind. I guess the forum is already live and working.

Going to switch the IP today. Forum may go down.

The input potential meter lowers the signal so then it's not as loud because it has to amplify it a lot due to how an LM 386 is. For the gain you might wanna look up the Ruby amp schematic and follow how they handle pins one and eight, or look at the LM 386 data sheet for the info.

Quote from: Microtone on Today at 07:06:56 AMI am considering using the little gem circuit as an overdrive circuit.
I simply want to put the circuit in a pedal, without changing any values, and use it between the guitar and an amp.
Will it maybe be too loud?

Loudness can easily be set by Master Volume pot setting..

Take into account that LM386 minimun gain allowed is about 9 (not compensated for gain of lower values..) so it should be a good idea to place a pot between IN and input capacitor to be flexible enough for signals of high amplitude and low gain combination..

Thank you for your reply. I fear I may have already waded in out of my depth! What exactly does minimum gain mean? And the same question to high amplitude low gain combination! Is that to do with the input signal?
I went ahead and built the circuit into a pedal and it seems to work nicely with a medium output single coil guitar as well as a higher output humbucker guitar.
But I'd love to understand the implications of the caveats you mentioned, to ensure it's versatile.
At the moment I don't have a gain control in the circuit, so it's always at full gain with just an output volume control. But if I were to include a gain control, what would I need to consider for the high amplitude low gain caveat? And how does a variable resistor on the input help that? Would that not just reduce the voltage of the input signal?

The green leads are connected to sleeve lugs. He's used a stereo jack for the input to switch the power to the battery (which is why the + of the battery clip is connected to the ring lug, so it connects to gnd when a mono jack is plugged in).

No wait, I'm wrong and Duck_Arse is right, I think.

If those aren't sleeve lugs the green leads are connected to, then there wouldn't be power to the circuit (as ring wouldn't connect to sleeve) but there would still be power to the LED! Those are switching lugs maybe? So they'd do the opposite and connect the power when the circuit was UNplugged...? Connect the green leads to the lugs actually touching the sleeves at the top of the sockets and all should be good (though I suspect the LED will stop working).
