Flame-On! Greasebucket Praise!

    Hey everyone,

    Some love it, some hate it, but I must say that I personally really dig the new(ish) greasebucket circuit on my American P Special. I play on a lot of hollow-stages and it helps cut down on the "woof" factor, while still sounding like a P when backing-off the tone knob some. So there you have it.....I dig it! :hyper:

    I see no reason to flame you, Fred. you're a nice guy. but here's a bump so others can berate you.
     
  3. I like it, too. :) I've modelled the tone circuit in my Affinity after it. Really helps the 1/4-pounders to not get too fat.

    What, really, is the difference between the Greasebucket tone circuit and the regular tone circuit?

    I mean, both the difference in how it's wired, and the difference in the sound.

    Well, StuartV is asking the wiring difference but I'm remarking, "what is the difference?" I had a HYW I Jazz Bass with the so called, grease bucket tone thing and I heard absolutely no difference between it and a standard tone pot on my other J Bass!

    Whatever!

    No issues with it on my Am. Sp. Jazz

    From what I understand, all it does is remove the low mid boost you get when you roll the tone all the way off. It seems like you could get pretty much the same effect on a normal tone knob by rolling off a little less.

    Doesn't bother me at all on my Hwy One Jazz. * shrug*

    Exactly. It seems to lower the frequency that tends to resonate on hollow stages. It does not make a P sound thin either. I think it's great.

    I wondered about the wiring myself. I read it involves another cap and a resistor added to the Volume pot.
    Is this pretty much a greasebucket circuit from MojoTone? It is their standard wiring kit.

    Looks standard with the exception of the "volume mods cap and resistor".

    Here's the Greasebucket schematic for those interested in how it's wired compared to standard (from the SGD Lutherie site).

    Interesting. Thanks, mongo!

    I'm tempted to buy a couple of parts and just try it out. I added a tone circuit (exactly as shown on the left) to my SB-2. It would be easy enough to change that around to work like the diagram on the right. Hmmm....
     
  14. I hate reading diagrams like this. -_- They always make me think I'm supposed to put a lead in the middle of the resistor.

    They just make me feel dumb because I have no idea what they're saying. :atoz:

    The resistor with the arrow in the middle is the pot itself. A pot is a variable resistor. So the arrow signifies that the signal could be anywhere in the range from the minimum resistance of the pot to its maximum. We call it a "wiper"in many cases. So there actually IS a lead in the middle of the resistor so to speak. But it is one of the terminals on the pot. That's what the knobs on your bass do. They increase or decrease resistance as you turn them.

    Short version: The pot moves that arrow up and down the resistor (in an over simplified kind of way).

    Here's a question. How do you know (other than opening the thing up) which ones have it and which ones don't? (My 2008 Precision V for instance.) I've never really put any thought into it.

    The tone circuit on the G&L SB-1 is similar to the grease bucket. It essentially only lets you roll the tone most of the way off to avoid the shift in the resonant peak. I find that it also means I have a more usable range of tone settings.

    That's probably because there is a lead in the middle of the variable resistor which goes to what's called the "wiper" contact which is designated by the arrow.

    as equipped stock from the factory:

    ... Highway 1's from about July of '05 until 'upgraded' to Highway Ones in '06, and then until the model was eliminated ...

    ... American Specials from the time of introduction to present ...

    however, if purchased used, modifications may have been made and/or the GreaseBucket Circuitry may have been eliminated so yes, you would need to look in the control cavity ...
