(Re-posted this one as it was lost in the site going down the other day).
A while back I posted a schematic for a pickup tester box I had designed, and then took it down when I realized that it had some trouble spots. It might take a while, but I'd really like to get back to figuring out the designs, and I think I've got all the major guitar modifications, but I wanted to see if there was anything common that I was missing. Here's what I've got so far:
Inputs/pickup selecting: I'm planning to have 4 inputs (3 is common, but in case I ever decide to make a double Jag or something like a DiPinto Galaxie 4) with both 1/4" input jacks and wires with soldered alligator clips (so I can test pickups in a guitar that aren't wired in at all). I haven't decided for sure, but I'm thinking about making 2 sets of 2 inputs separate, with a phase switch, series-parallel switch, and a 3-way selector (1/1+2/2, 3/3+4/4).
Volume pots on a rotary switch for multiple values (250K, 500K, 1M, and maybe 330K) to quickly compare the different values.
Tone pots on a rotary switch for multiple values (250K, 500K, 1M, and maybe 330K).
Capacitor values for tone pots on rotary switch to compare different values. I also plan to have a place to add external capacitors to this switch.
Bass cut pot (maybe a switch for different values?)
Strangle switch (yes I know it's almost the same as having a bass cut pot)
Phase switching (don't know if I'd need any more, but maybe)
Series-parallel switch
Kill switch (2 different types I've found)
Cocked wah capacitor switch
Gibson-style Varitone
Here's an example of a simple box I made a few years back that includes a rotary switch for 3 different pot values for both volume and tone, a rotary switch for different capacitor values, and a switch that adds the tone capacitor between the volume and tone pot like some old guitars do, or between the tone pot and ground like other guitars I've found are wired. Don't know if that last switch makes a huge difference, but I thought it was cool to add...
Anything else I should include? I think I've got all the common mods, but I can add anything I want really. I am making this for myself, but I'll draw up the schematics when I make it so any of you guys who build things all the time or any pro builders can use this. With some switches, pots, and wires, I can't imagine it would be expensive to make.
