The Benson Preamp is pretty popular, but 2M pots are hard to find. This is a modded vero layout using a 1M bass pot. To make this change and keep the same frequency response, resistances are halved, capacitance is doubled. Note that the Drive pot value also had to be halved. I’ll add a regular size … Read more

Quite a detailed explanation via the link above, including a schematic, LTSPICE model traces, audio and his vero layout. What a solid effort. For me, this is useful, as it has a standard … Read more
