    Hi, I was discussing with Shenanigans about a problem of passive blending I had, with a Bass Big Muff, and he suggested using a buffer to avoid it.

    It actually worked (I used an old Boss BE-10 I had lying around) but I wanted to see if I could achieve the same results with a smaller pedal.
    I've found that Analog Man actually makes those gizmos (here) but since they seem pretty simple devices I was wondering if anyone has the schematics to build one myself! (Ok, well, with the help of a friend who is more into soldering and circuitries… :D )

    Any help?

    if youre willing to go down the rabbit hole, various types of spiltters and blenders are basically just buffers and pots. Be prepared to not get a lot done on bass while you get into electronics though :p

    Breadboard layout for a simple, buffered, blend.

    Thanks, everybody… the one with the blend might be even overkill though… I'd like something really meat-and-potatoes, like "input jack - THINGIE - output jack"
    Probably the BJFE model is fine, but on the other blog, too, the one with the Guitar FX Layouts, I did find something that might be right.

    Is that right? :cool:

    Amz stuff is always tops, so I'm sure either would be great. I'd be happy to do a layout this afternoon of the BJFE, if wanted. I know the BJFE is super transparent, first hand.

    The amz is probably great, but I've never used it, especially on bass, and since you're not using it for long cable runs, I keep it simple and use the other one- the picture i posted is a fully 'ready to box' circuit. They included protection from real world failure.

    Really? Could you? It'd be much appreciated! :smug:
  9. I've used the AMZ-FX jfet buffer in a few effect loop pedals and other pedals for bass and it is totally transparent and works well. Best thing is, it's extremely simple and will fit in a tiny enclosure.

    In the end I got this one… it works fine, as far as I can tell…!
