    Source selector switches

    Quote: - but are you sure about the quoted part? there's enough ways to wire an attenuator that i'm easily confused. let's dive into my confusion. put it in the direct signal path as you say. it has various steps of resistance. the least produces the most sound, and the most the...

    Source selector switches

    is there a trick in the question that i'm missing? you'd want non-shorting, otherwise you'd be feeding in two sources at once, briefly. shorting would be for a stepped attenuator so you don't briefly have zero resistance and thus full gain.

    Are there any DIY kits available besides...

    sygyzy, take their advice and figure out how to assemble your own parts list and order parts from digikey and mouser and suchlike. it's definitely intimidating at first, but it's a skill you likely want to learn because you'll likely want to build more amps. i highly recommend the cmoy. it's...

    Advice for noob

    if you're completely new, start with the cmoy. it does sound good, and it's a much better place to make your first mistakes. (and mistakes are just part of learning.) gsferrari, i believe the meta42 is discontinued in favor of the pimeta. mainly because the buffers are now unavailable. can...

    Enclosure Types

    Quote: Originally posted by JohnFerrier I've wondered how easy mu metal is to cut, drill holes in, and possibly bend. I noticed in the link you provided that it indicates that mu metal is worked like stainless steel. I'd like to know if that means that it is hard for a DIY'er to use...

    The great project: amp for electric violin. Help!

    no offense to the crew here, but i wonder if you might do better to try any of several active guitar amp forums on the net. one of those might even be able to hook you up with other people doing violin amps. and it'd be pretty fun to plug a violin into a big ol' Fender.
