  1. Wow, he stole the “Crackle not ok” too?

    1. same topology, but the changes in the component values in a simple circuit make the differences...and after all it is another common source circuit and that is something like the pizza margarita of transistor schematics ( together with the common emitter circuit ) and these schematics have been around since the dawn of transistors- and the god city not okay is very similar too-i would not call it stealing, it is picking up what was lying around anyway

  2. Hi Fuzzhead, Thanks for all your hard work — much respect. I've noticed that lately you've released a lot of EQs and boosters. Would it be possible to request a pedal that creates a stereo image from a mono signal, if such a thing exists? Or is the usual approach to keep one channel dry and apply a chorus effect to the second channel?

    1. A simple signal splitter would suit your needs:

      A true stereo signal is when a single source produces a sound that propagates differently (i.e. differences in phase & harmonics) in sixteenth directions in acoustic space. "Stereo" electronic instruments, whether it's a synth or a guitar, are really just dual mono until some kind of effect (chorus, phase, reverb, whatever) to differentiate between the left & right channels.

    2. *different directions in acoustic space, not sixteenth. What an odd autocomplete.

    3. Hi Sebastian, thanks for your input. I have a splitter, and also modified a SHO with input split to 2 independent output and a stereo pot. I could share the veroboard. I just wondered how to create a different stereo image. Pan!? I saw there is a EHX Pulsar stereo output, for example

    4. Panning is just creating a volume mismatch between the left & right channels: down in one, up in the other. A stereo tremolo, like the Pulsar, does exactly this, just really fast and back & forth between the left & right channels.

      It sounds like what you want is a basic dry/wet biamped setup. Unless it's got some weird dual-output wiring, a guitar's output is mono; to get a stereo image of it, split the signal and then effect one of those signals to create a difference between the two. Anything that effects the pitch or time of one channel will sound more dramatic than a clean/dirty split.

  3. needed a small boost for a fuzz circuit. this layout works as intended and can be verified.
