LPB2

[jasonober]

I've built 2 LPB circuits that i want to wire off of one switch to change between the two without bypass so that i can set different amounts of gain for different guitars( HB or SC)          any suggestions?

This is the switch:

to LPB 1 input---|      |---to LPB 1 output
to guitar input---|      |---to amp output
to LPB 2 input---|      |---to LPB 2 output

What about to run 2 of them at once? Obviously would require different switching, but would you need to alter or remove any of the input or output caps?

Hello, and welcome to the forum. This is how i would do it.
Follow this schematic:

now that shows one channel and bypass. Now do you see the shorting wire on the switch? Remove that, and use those two leads as they are used above. If you have a 3PDT switch, You would have used two/thirds already. Use the remaining swith as follows, put 9V to the middle, and an LED and resistor on both sides. This gives you LED indication. Now, if you want, use another switch to get Bypass over the whole effect.

hey thanks for the help    can probably handle it from here i'll let you know how it went.

so   aside from ab boxes and a true bypass switching system this was my first build and with the help of this forum it's successful (no debugging!)    I guess now i'll start thinking about an enclosure    thanks
