Hey all... Looking for some help... I have my current Bass around 10-15 years now. I'm not certain exactly how old it is, but I'd say I bought it in the mid nineties or so. It's a 4 String Active Electric Bass, sunburst colour, with 24 frets. It's got Rhino Aria Pro II on the headstock, a serial number ( S7041294 ) on the back of the headstock and Made in Korea on the back of the neck. It has two pickups, one 'single' bar near the neck and two 'double bars' closer to the bridge. All the pickups are plain black, with no 'metal coil' visible on them and they have Aria Pro II written on them. There are 6 controls, four Pots and two switches. One pot controls overall volume, one controls bass, one controls treble and one controls which pickup is being used ( i.e either one pickup, or the other, or both, but as it's a pot it's not just on or off, it's gradual between on or the other, with a centre point of both together equally ). One of the switches is an on/off switch and from what I can see it turns off the active part ( so the Bass and Treble Pots don't work anymore, though the Pickups Pot still does ). The other switch is three way, and I've no idea what it does, though I can hear slight changes in tone when I change it. So, what I really want to know is exactly what model Bass do I have, is there any documentation out there, and what does that final three way switch do? I've done pretty extensive searches for Aria Pro II Rhino basses online, but it seems to be a fairly generic name, not a model name, and I can't find it on Aria's own websites. I can post pictures tomorrow if that'll help... Thanks in advance... J.
