Two courses of action:
1.) Contact the manufacturer web-site or Customer Service personal & ASK what is the electronic value of the unit in question (the pot's resistance spread) and who made it as you need to get a replacement.

2.) you get a multi-meter and take a lead from the center to the active side and turn the pot as best as you are able as see what the meter reads. It's easy. The pot will have 3 solder connection pin-outs. The center and one side will have leads soldiered to it; on those you place the probes and you turn the pot. You won't get zapped nor will you harm anything; you're simply getting a reading
Alternately you can get a very good magnifying glass and get ALL the information stamped on the pot and post it. It's likely that the mfg will have a letter code, but that not as good as getting the info from the mfg or your own readings.

It will look like this:
xxx Series Guitar Potentiometer (mfg would be someone like "Bourns") Value would be (generally) in Kilo-ohms 100-250-500 or whatever. The stock # would be quite long. IF you can get that info - the cost from buying from an electronics supply would be around 8-12 dollars. buying from some middle-man supplier could be quite a bit more!


-=NOTE=- Part # reference will have a distributor # and a mfg #. They will look like this:
Mouser electronics reference # 652-95A1DZ2BEA0300L (note all "0" are zeros) is part reference for standard 250 K-Ohm. Bourns Guitar pot is 95A1DZ28EA0300L for 500 K-Ohm (500k-ohm ends w/ A0302L)

The B 104 looks to be an active bass. Is the pot attached to a circuit board? (you'll need to look inside the back of the bass to answer this). If it is, then you might have to visit a tech, or look into replacing the board:

The ESP Guitar Company | 2011 USA Website

If the pot is not part of a board, then you might be able to tell the resistance by looking at the back of it, or (above). Once you figure out exactly what you need, there are numerous sources for the parts themselves. An example:

The pic doesn't detail which p/n it is. Looking at the add'l pix provided it looks like the EP-0085-000 or the EP-5485-000 would do the trick.

A word of caution: I'm not an expert on these. I've replaced a couple of pots, and the outcome was successful in both cases. But if anyone more knowledgable wants to add their input, feel free...

Glad to help. Looks like the change/fix shouldn't be too much of a hassle, and the price, for a decent quality CTS pot, is pretty reasonable. Good luck, let me know how everything comes out.

It's a 250K Linear taper (B) pot. You can get them anywhere that sells guitar parts. Any one of them will work fine. Just make sure the shaft is long enough to fit through the wood.
