after building acoustics for a while ive decided to try buidling a strat. i have more or less no idea what im doing regarding the wiring and electronics portion. Given my complete lack of understanding, ive discarded the stock strat schematics in favor of a "super strat" or "strat elitist" setup. im using this kit store.guitarfetish.com/wh3supiwikit.htmlwith this preamp store.guitarfetish.com/kimibocrtusc.htmlEach single coil is wired to its own on-off-on (dpst?) switch, which should give me all the regular pickup permutations plus some out of phase ones. Im confident i can folow the supplied schematics, but id like to add an active push-pull circuit in leu of one of the tone pots and am not entirely sure how. gavinh.net/schematic.jpgthis crude picture is my combination of the schematics for the switches and the active preamp. will this work? thanks

Hi, gavinh, and to the forums. The switching scheme looks all right, and would give lots of parallel combinations, if you're a fast switch-flicker The wiring of the tone control seems a bit odd to me. When it's in the full CCW position (from the viewpoint of the drawing) the hot of the middle pup would be directly connected to the hot of the neck. When either was selected, you would get both. That seems like a strange function for a tone control. When it's turned full CW, the neck pickup is directly connected to the cap. It would have a strong effect on that one, and on any others in parallel with it.Hummmm. Let's say you were playing with the bridge alone, and the tone control was all the way down. It wouldn't have any effect, because the control isn't connected to the bridge pup. If you switched on the neck pup, the tone control would suddenly kick in full force on both of them. Perhaps that wasn't quite what you had in mind

im pretty fast with the switching , so if that part looks good ill stick with it. i ditched the 5way mostly because it always got in the way of my strum and id ending up knocking it into a different position. as for the rest.....yeah... thats not really what i had in mind. im not really sure how to handle the lone tone pot. ive never played a strat with a single tone, so i dont really know what it can be used for. i guess this is what im looking for: -id like the volume to funciton as a master volume for whatever combination is in use -id like to not electrocute myself/set my nitro finish on fire -id like the push/pull preamp to be able to kick in when engaged and not do anything when not engaged -id like to do something with the remaining pot space. i suppose a tone control would work, but im not sure how to wire it. also, will it only function for one pickup, ie: will it only be used ot adjust treble or bass? i dont suppose a single knob could do both (?) (although i have seen amps marked with a single "tone" knob). -caps: ive been reading a bit on capacitors, but im not entirely certain of their use. do i need to use any this configuration? im not entirely certain where im going with this. any help is appreciated

I ducked back to correct a mistake that I made above, but you had already replied. I'll try to make amends with a drawing of a basic master volume and tone control. Check. You already have that in your drawing. You aren't likely to set the guitar on fire with a 9-volt battery, even if they do say that it's a "hot" preamp. ;D The description says that you can turn it on and off with the knob. The usual type of guitar tone control cuts down on the treble, so the mid and bass are more emphasized in the sound. The question of which pickups it will affect depends on how it's connected. If it's connected at the output, after the selector switch(es), it will affect whatever goes to the output. Your drawing already shows one between a lug of the tone control and a ground on the back of the pot. That may not be the best place to ground it, but that part is fine. An excellent source of information is the original Guitar Nutz site. If you poke around a bit, there are wiring diagrams and information for beginners as well as more advanced types. Hope this helps.

you might want to review the grounding scheme, as well as the -9v connection.
