So I have an Epiphone Toby Deluxe 4 string. I like the sound very much, I like the playability, it is very lightweight which is great for the back (3,4kg/7p8oz) and it looks stunning, much like a boutique instrument. Especially in stage light when the "walnut" finish seems to fluoresce. But the bass is noisy! Our music school offers band coaching (which by the way is a great thing to do). Our band coach, a multiinstrumentalist who has quite some experience with different bands, says that he has never experienced any bass that was as noisy as the Toby. He likes the bass as well, and has even recommended it so his girlfriend, who is a beginner bassist like me (2 years), and it is just the same with her instrument. So I know I did not just get a lemon. Now there are some obvious answers, but none of them seem to apply as far as I can tell 1. "Single coils always hum!" It is no single coil! Epiphone lists them on their website als "Tobias TBT™ Dual Rail Humbucker pickups" so I think they must look like this(link) noiseless pickup from another tb thread: Two long thin blades, each wrapped with a coil in opposite direction so that they produce a humbucker that just so fits the jazz format. Also, if they were single coils, the noise should go away when both pickups are full on, but it does not. I cannot be sure about the pickup design though, because it is not possible to remove the cover, which brings us to typical reason number 2. "There is a loose wire in your pickup, you have to mold it to make sure nothing can move!" Well, the pickups sure look molded to me, which I would never have expected from such a cheap bass: Which brings us to the last of the usual suspects: 3. "You gotta shield the electronics!" Well I did: I checked that all copper parts are interconnected and to the ground (outer ring 1/4'' jack) using a multimeter. I also disconnected the bridge wire after shiedling as recommended. No effect whatsoever. So the factory shielding using conductive paint may or may not have worked, but it is not the culprit. I refrained from exchanging the pickup wires with the shielded ones I had ordered after I saw that a) the factory wires look exactly like the shielded ones I ordered and b) the wire was molded into the pickup and I might just cause another shielding problem if I cut it off and resoldered it. So, from all I can tell, Epiphone did everything just like it is supposed to be done to get the instrument quiet, and still they ended up with one heck of a noisy instrument. So what on earth went wrong?!?
