  1. yes, a coil splitter just turns on one of the two single coil pickups inside the humbucker.

    ::edit::

    don't mind me. i cant seem to respond fast enough. keep getting beat lol

  2. very nice, im making one like that in my woods class, but im not sure where to put the input. any suggestions? :D

    put it close to your control cavity. I would opt for the same side shown in the pictures from the link. that way it's close to the strap and you can hang it over the strap when you play or run it to a wireless transmitter if you have one

  3. operational amplifiers are little IC (integrated circuit) chips that are usually sold as the LM741 (the kind in your schematic). Radio shack sells parts online, but you might be better off at an electronic supply store that would have those capacitor values. also, you have a lot of op-amps, so you may want to look into getting LM324's which are quad op-amps. get three and you have 12 op-amps right there. here is a link to the datasheet, hopefully the ratings will be good enough for your application:

    ::edit::

    the slider switches you mentioned are potentiometers or pots for short. google electronic supply and look around at different places. many stores sell all the parts you need: resistors, capacitors, pots, op-amps, etc.

  4. do you know if you were touching the strings or bridge when you touched the jack/cable? i have also had this problem and am trying to fix it. I know that the reason for mine is because I haven't gotten around to sending a ground wire to the bridge. When I touch any metal that is a part of the electronics (pots, jack, etc.) and the bridge or strings the hum goes away. if this is the case with your guitar you may need to check the ground connections inside

  5. sure. the values are in a good range. otherwise i couldn't say what's wrong. I guess it could be the pots sent were not actually linear. the only way i can think to check would be to use the meter and measure across lugs 1 and 2 and graph rotation vs resistance in excel or something. good luck with it. wiring always seems to be the hardest thing to troubleshoot. cant ever see whats going on

  6. thats odd that it would do that. I had that same effect when I put .047 caps in with 500K but that was because the cutoff freq. was then different, not because of the pot taper. I think the only logical thing that would mess it up is the resistance of the pickups. if you have a digital multimeter, it can measure resistance across the + and - ends of the pup. if the resistance is high enough, it could change the equivalent resistance that effects the .022 cap. the problem could also be the wiring touching in places it shouldn't. other than that, 500K and .022 usually give you the right cutoff frequency and the taper of the pot should have a noticable difference if its linear.

    good luck,

  7. Pots are basically resistors that change resistance when you turn the knob. The lugs are usually wired the second way, with hot into #1, out from #2 and ground to #3. when wired like this, the pot creates what electronic-studied people call a voltage divider.

    when you send a signal through a resistor, the voltage drops by a certain amount. when the signal is turned into audio it means the volume drops. your pot basically looks like this picture:

    the jagged lines are resistors, which change as the pot is turned. the bigger the resistor on top the lower the volume.

  8. I'm not sure what you mean, suicide...

    You don't have to go to your vol knob directly from your pickups.

    true, but the output from the pickups does hit the volume put first, either from the pickup itself or from a switch etc..... at least from what ive seen. i should have worded my reply differently

    I wired mine thru the tones then thru switch then to volume. idk i guess anyway works

  9. Yeah nice job on the whole thing. I totally know what screwing up the FB is like. I cut off the first fret by accident thinking it was actually the nut... good thing I figured it out before I did the neck joint. but I could've easily ended up with a short-scale, 23 fret guitar. anyway nice work, esp. on the finish

  10. All I know about Abalam is that it works when you need a big inlay. The quality would be good for fingerboards but abalam tends to have bubbles between the layers and the layers can be sanded through on rounded surfaces. otherwise it would work fine.

    edit:someone posted before me. i agree

  11. Hi. I recently completed my first guitar and I would like it to be considered in the Guitar of the Month Contest.

    The guitar was made entirely from scratch and it is completely custom. For a nickname, I guess I'll call it "Mean Green"

    ::EDIT::

    Some people have requested to see pictures of the building process. You can follow my link if you want to see them:
