  1. Hi guys, I just tore apart my cheap floyd rose copy to clean of tobacco smoke and other junk. It has a diecast base to it with a rather low iron content (magnet test). I happen to have laying around a base plate made of stamped steel (like an a original) and it has all the same dimensions except that I'd have to drill and countersink the holes for the screws that hold the trem block on it slightly larger. What kind of tonal differences exist in these two and which is most recommended?

  2. switch where the inputs and outputs go on the pots to decouple them. Otherwise, it'll do wierd stuff like a Les Paul does, like it'd kill the whole signal if one volume is at 0, and having the pickups reduce the overall inductance giving you a wierd sound.

  3. My dad repairs welding machines, and one common problem they have is the pots breaking in tig controller pedals, it appears that construction welders aren't easy on their gear, it usually isn't the pot scratching it the gear being ripped off of it from too much pressure. Being a nuisance job, it isn't worth them what they charge to change them. So armed with a new weeping demon I'm gonna be making some pedals based on the optical system in it, because the welding industry hasn't caught on yet. My prototypes will be a dual volume/tone pedal set up, cos the volume pedal is essentially what is needed, but with a different pot and a few other resistors. And I want a volume pedal.

    I plan on making a retrofit unit eventually for them to fit be fitting.

    I'll be hopefully making the first prototypes this week from some 3mm ply, and later if they are good, I'll do them from aluminium.

    If anybody has any experience with optical pedals, I'd be glad to hear about what works and what doesn't.

    If it works well I'll make a tutorial, cos optical pedals are way better IMO than pot based pedals, and I'll be designing a superior wah(if things go well) soon. I say superior in the meaning that It'll be the best parts of the crybaby(old skool ones), with the technology of the weeping demon, and my own mods added in for good luck.

    And thanks in advance if anybody can help me out.

    ooh, and if anybody has a whammy schematic(I'm not joking either) I'd like to see it

    thanks

    Check out Morley Wah Pedals.

  4. What effect does the resistor in parallel with the cap have?

    It let's some more of the lower frequencies through and lets the cap discharge quicker as it lowers the load resistance in parallel with the cap.

    I find just a cap by itself kills the harmonics kind of for me.

    Also, If you wired a cap and a resistor in parallel and ran it in series with a signal, it's called RC coupling, and I'm pretty sure it gives a rather pure signal except for a peak frequency that shifts in phase.

  5. Man you got your work cut out for you! I'm willing to assist in the R&D of the electronics if you want, it sounds like a really fun project!

    I've designed a passive, humbucker sized pickup that with the flick of a switch can do many different combinations of sounds (humbucker, single coil which would go along similar lines as the 513. I still gotta makea prototype, but I'd bet that applying an Evo type design to it may lead to further versatility, but it can't be sold that way due to patents.

  6. I'm making a guitar that has flat frequency response magnetic pickups and runs through a specially designed analog filter than should in theory be a little more accurate on modeling electric guitars, at least as far as the pickups go. It will pick up and cancel out harmonics just like a normal pickup would because of what area of the string is being picked up. It's been a long road designing it, but I have less than a month to be done with it as it's my senior project for electronics.

    Since the pickup design I came up with is hexaphonic (one for each string), I was actually thinking whether or not I could make a MIDI pickup that had better tracking this way, instead of with piezos, but that I'll have to save for later.

  7. Slap me if I'm wrong here, but isn't the common (-) supposed to be connected to the ground? That would mean that ifyou measured across the common and ground, you should get 0 volts as it's shorted out. If you get a voltage then obviously it's not right. There could just not be a ground wire attached, as well/ The last owners of our house upgraded from 2 prong to 3 prong and never changed the original wiring itself.

    ONE THING'S FOR SURE, ALWAYS WEAR RUBBER SOLED SHOES OR YOU ARE AT MUCH GREATER RISK FOR BEING THE SHORTEST PATH TO GROUND! Obviously, you were. Considering the amp is probably isolated from ground by the transformer (s), your problem may lie in that.

  8. I think there is no need to flame this guy, as long as he knows that the overt promotion of a guitar for sale is not to be posted in this section of the forum.

    Exactly, he probably just didn't think about what he was doing, and for us to insult him would make us scum, it's really quite disrespectful.

    I got a question, BTW. How many hours would you say it took to scallop the fretboard? I'd think after doing so many neck, you'd be a tad more neat. If you haven't checked out the scalloping tutorials on projectguitar.com, I'd check it out, they have really useful tips!

  9. Careful guys, I don't want to see people "unleash the fookin' fury!" :D

    But I gotta admit I don't like seeing people try and use a forum that's supposed to be for reference and to show off your results and use it as a marketing tool. No offense, but I'd keep it as I doubt you would profit for your labor. :D

  10. I think on the output section of a solid state amp that the impedance is determined by a capacitor and a resistor in series with each other in parallel with the speaker (s).

    BTW, I've never heard of an output transformer on a solid state amp, impedances can be converted easily depending on how you configure the amplifier stage.

    Edit: the speaker cab would most likely sound like ass because it's resonence is probably more in the treble and bass response, where as a guitar amp needs a lot of midrange to cut through drums and vocals. If you're totally scooping the mids when you're performing, try adding more mids and see how you like it! It doesn't sound the same as playing alone, trust me. Kerry King uses a graphic EQ to boost the mids on his amps while Dimebag Darrell (rest his soul) scooped heavilly. Which one is more likely to make your balls hurt when cranked? :D

  11. Ted Nuggent would be proud   :D

    Yeah, kinda reminds me of his loin cloth! :D FYI, you need to wear earplugs, THEN gunner's muffs to that dude concert to not break the threshold on your ears! I learned the hard way...

    Great job, I'm sure it will look much more distinct and professional after the clear is applied!

  12. I'm leaning towards a guitar with a humbucker in the bridge and a single coil in the neck, but it's good to see it'll work either way.

    A piezo in the neck pocket can be used to give the driver the signal? I have one of these (http://www.stewmac.com/shop/Electronics,_pickups/Pickups:_Guitar,_Acoustic/Schatten_Soundboard_Transducer.html) lying around, could I use that?

    Edit: Opps, my bad, thought you were saying it was the driver!

    I believe it will work, Piezos like that can feedback like crazy!
