    Sorry...I wasn't paying attention to the fact that this is your business/dealer thread.

    I don't think they'd object to excellent customer service you help deliver :)

    We have long shaft in stock. More of the regular shaft should arrive in 1-2 weeks (assuming our supplier sends them).

    We'll let it slide ... this time. ;)

    Question on the difference between log and linear pots. For my tone pot (when you get them back in stock), don't I want a linear pot? The logarithmic one reads that you only get 10% of the max value at the 50% mark. Don't I want it to be 50% at the halfway point?

    There are 3 main types of pot tapers most commonly used in guitars: Linear, Log, and Reverse Log.
    [​IMG]

    1) Linear = A straight line progression from approximately 5% to 95% turn of the pot (not 0-100 like most people think; there's always a safety margin at either end of the sweep).

    2) Logarithmic = A much more gradual progression by having more resistance in the first half of the sweep. You can get log pots in any sweep from 5% at half up to 45% at half. 10% is industry standard in our industry, so that's what you'll see most commonly. Many of the expensive/premium "custom taper" pots are just log pots set to 15%-30% at half.

    3) Reverse Logarithmic = Same as Log, just reversed. So, 90% at half turn is most common. Used in left-handed guitars.

    There are numerous other tapers (CT, W, S, etc.), but they are less common, so I figured I'd stick to the above...

    Logarithmic pots are the most used in instruments with passive pickups. Volume and tone pots alike are most commonly log pots (with the standard 10% taper). That said, there are few "rules" when it comes to this stuff. Many people experiment with different tapers and resistances until they find what works best for them. Like most most things, it boils down to personal preference, mostly derived from years of tinkering.

    So, the short answer to your question, "Don't I want a linear pot?" is, depends on what you're after. If you're replacing a pot and trying to keep it to original spec, you need to figure out what the original maker used. If you're upgrading your tone pot, it might be worth changing the taper if you are unhappy with the response of the pot have now (or had before).

    Hope that helps and doesn't muddy the waters too much!

    No, this is quite helpful. Been doing some research and it seems the human ear “hears” in a logarithmic fashion, not in a linear fashion (which is what I thought). The common default approach seems to be Log for Vol and Linear for the Tone.

    Re; Pots.
    I'm looking to put a 'blend' pot in my PJ bass.
    Is there a difference between 'blend' and 'dual gang'?
    Or are they the same with different names?

    There is a difference... A dual gang pot is any pot with 2 sets of lugs and 2 resistance tracks. Although they share the same shaft, they operate independently of each other as the pot is turned. There are a lot of available combinations of tapers, resistances, etc. It's as if you have two separate pots, but they share one shaft.

    A "blend" pot is a particular type of dual gang pot. If you go with a blend pot for the PJ bass, you want a dual gang MN taper with a center detent. "Center detent", meaning, you'll feel a notch at a half turn so you know when you're in the center position.

    We don't currently stock them, but can special order them. Contact us for details.

    Personally, I haven't found P & J pickups blend particularly well. None of the blended areas sound good to me, except for the 3 that would be available on a pickup selector switch (one or the other, or both together). So, I'd go with a switch instead. Easier to change quickly on the fly too. Just my experience.

    That was my other option as well.
    The blend was so that I could kill the volume with one sweep.
