    I'm highly opinionated and extremely self-assured
    You can use anything that isn’t polarized.

    I think you'll find there will only be a few in all those that have a value useful for bass guitars.
    For instance, there are none here that are worthwhile even trying:

    These are polarized electrolytic, you can't use those:

  4. Type of capacitor is not really and issue but size is. Higher the voltage rating the larger the capacitor. I try to stay wit 50volt and certainly no more than 200volt as going larger take ip a significant amount of space

    Assuming a non-polarized capacitor, material is irrelevant for passive guitar circuits. It’s the value that matters, so it’s worth using caps with at least a 20% tolerance (grab a few, since the values will vary a bit) or 10% tolerance (in which case, one of your desired value will be fine).

    You should use a capacitor from a company with a good reputation for value tolerance consistency in order to get the tonal characteristics desired in the circuit

    Please stay away from oil-and-paper capacitors, because over time the oil dries out and the capacitor value shifts.

    Unless you are restoring a vintage instrument where the original capacitor is required for aesthetics and collector value, you don't have to pay too much for a capacitor, so long as it is from a reliable manufacturer, like Sprague, Mallory, etc.

    This is important to understand. In an amp, the signal actually flows through certain capacitors so they can affect tone, but in a passive guitar tone circuit, the cap is not in the signal path. I once wired up an Orange Drop and a generic Radio Shack cap on a switch in a guitar tone circuit and heard no difference at all. It makes sense when you know how the circuit works.

    Last time I looked you could get ten ceramic disk caps from StewMac for around the price of one Orange Drop. I checked the last batch I bought with a multimeter, and I don’t know what their claimed tolerance is but they were all quite close to their intended value.
