In the last episode of The SR500EPB Saga we discovered that Tim purchased a used Ibanez SR500EPB from Reverb, and it arrived in less than professionally setup shape. He sent it off to Guitar Center for a Platinum Setup Service, and it returned in less than professionally setup shape. So, with a little bit of research he set it up himself and was happy with the results.
Now, on to today’s episode!
So, I was never really happy with the sound of this bass, and with some experimenting over the weekend I realized that the mids on the bass were dead. It wasn’t putting any mids out. I’d turn down everything on the EQ but the treble, pluck a note, and hear it. Do the same with the bass, I’d hear it. Do the same with the mids, almost no sound came out. So I popped out the pickups, opened up the electronics cavity, and did some snooping. I discovered that one of the mini solderless terminals was plugged in at an angle, so that only one side was making connection. I plugged it in completely, and viola! The mids passed the EQ test I described above, and the bass sounds great now.
Except for one thing, and this has been happening ever since I got it: if I sit too close to my PC, I pick up a bunch of interference through (I think) the pickups. I don’t seem to get it from anywhere else but the PC; I’m sitting under neon lights, right next to a little refrigerator and an air purifier, but it’s only when it’s close to the PC that I’m picking up… well, honestly it almost sounds like a broken up modem tone.
This leads me to believe it’s a shielding problem. While I took a year of ITT Technical Institute and am no dummy when it comes to electronics, I’ve no idea how to troubleshoot a shielding issue in an electric stringed instrument… assuming it is, in fact, a shielding issue. It’s not a grounding issue, that I’m sure of.
Any thoughts or ideas on what to look for or how to insure it’s properly shielded?
