    If you hear the pick hitting the pickup cover, then that would indicate microphony. I really don't think that the sound of pick hitting string could have anything to do with microphony. When the pick hits the string, it creates a particular vibration in the string which you hear as the pick attack. I think the actual soundwaves generated by pick hitting string would have to be quite loud to be picked up in the same way your voice was. I doubt they're that loud.

    I've played a Starcaster. It had a fast low action. I played it through a crappy amp, so I can't comment on the tone. I wouldn't want one, but that's just cuz I could make a cooler guitar for $170.

    Pick noise isn't related to the pickup being microphonic. If you heard your voice in them, that's a clue. A microphonic pickup will give you high-pitched feedback at high volume levels, especially if you face the amp. It's not string feedback, i.e. you can't stop it by damping the strings. Melt some wax in a double boiler and pot them. It's pretty easy.

    Dude, you're funny. Of course blocking 60 Hz wouldn't be enough. But if there was wall voltage on your bridge, it would be 60hz AC. That's where it comes from. Hope it didn't shock you. I can't for the life of me figure out why you would put a cap there. That's why I was listing some reasons that somebody who doesn't know what they're doing might try it.

    I'd get some thin brass or a hardwood (maybe the same as what your neck is made of). Lucky for you it's not a big deal, pretty easy to fix.

    If you want midscooped, I would just play a Strat through a blackface Fender amp. Those amps have a massive midscoop in the tone stack. Other than that, I imagine that (as everyone has said) you would need some kind of preamp or EQ.

    I believe a capacitor's farads or microfarads determines its low-frequency cutoff. So (I think?) you could have a cap that will block DC as well as 60 hz AC but not higher AC frequencies. That's probably what the intention is with these things.

    I love it, dude. And I don't usually care for pointy guitars... yours is awesome.

    That's one of the coolest I've seen in a while. The woods look fantastic together. Love the fingerboard!!!

    This is off the top of my head, but I believe when a capacitator dies it goes to a short? If so, this wouldn't help at all in blocking wall voltage.

    Should work. Just make sure that each solder joint is nice and shiny and you should be okay.

    Any paint you put on the pickup is going to wear off from the pick. You'd be amazed at how much the pick actually hits the pickup cover. I painted some Strat covers black a while ago, and now they have a cool "chipped white and black" look.

    Popping? My gut says that could only come amplification, i.e. onboard preamp or else in the amp. But I may have misunderstood your description. If it's more like the sound randomly cutting out, that would probably be a bad joint somewhere between the pickup leads and output jack. BTW, did you eliminate the cable? Those things can get crazy when they go bad.

    I like it. Can apply to more than guitars.

    Tuner position is sweet, and the upper horn looks awesome, though I have to second Black Labb's question. The headstock carving is totally cool.

    Hmm... that will do for now... Okay, I'm pretty picky. I don't like modern mass-produced amps. sb... I think he did most of the work himself? That's the impression I got from following the other thread. I wouldn't assume that he couldn't do it just cuz he's fourteen.

    PM me with your email address and I'll send you the schematic.
  18. Geo
    Dude, it looks great. The design is very original and balances well between body and headstock. I hope you have a nice tube amp to do that guitar justice!

    Are you putting LEDs in the fingerboard?? A little more info might be helpful.

    Awesome. I built a 3 watt Plexi. It's my favorite amp and cost me only $50 in parts! (I built it into a gutted solid-state practice amp). I can share a schematic if you're interested. BTW Maiden, you can buy blank chassis too. You don't have to make it yourself.

    If you don't want to bother with fixed bias, you could build the amp cathode-biased. It would probably not be as powerful, but it would be simpler. You'd have to buy a few extra 5-watt resistors, probably in the range of 150-300 ohm? Instead of grounding the power tube cathodes, connect them together to the resistor and then ground the resistor. The value of this resistor will control how much wattage your tubes dissipate. So this involves some testing of different values and measuring voltages and calculating dissipation. You won't hear any difference in "loudness", but you just want to keep the tubes in a safe operating range. Then take the 220k's that connect the power tube grids to the bias supply. Connect them as shown, but instead of connecting their junction to the bias supply, ground it.

    Dude.... all I can say is.... SEXY GUITAR!!!!

    Looks great, dude. The blog looks professional! I'm curious as to what those necks are made out of. I agree that they look lighter than any mahogany I've seen (though I've only used about three or four different pieces.) But even in the pieces I've seen, there's a range of color, from a very light brown to a brownish-pink. But the pores of mahogany are pretty distinctive I think, and I don't see them in the close-up of the one neck. Not to put a damper on it... but you may want to make sure the necks are made from acceptable wood before you invest your time and energy (and emotion!) in building it. It would be heartbreaking to have the necks warp beyond repair after you finish an otherwise beautiful guitar.

    Totally cool, I love the simplicity and purity of the design. The "original" has even more "useless" frets! I agree though; the violin aesthetic is more important on this guitar than fret access.

    I'm using these for the P90 set I made. http://www.stewmac.com/shop/Electronics,_p...ckup_Parts.html The guitar isn't done, so I can't comment on them. But, touching a screwdriver to the polepieces of the assembled pickups, they transfer the magnetism very well. The feel as magnetically strong as an stock pickup.
