My new Euro 6 LX in haunted moss. Love this bass! May put an LHZ preamp into it soon, but the Darkglass Legacy that it came with doesn't suck at all, either.
I've never used Kalium strings but have researched them a bit. From what I understand, you can write Kalium, tell them your scale length, what you tune to, number of strings, and they will let you know what gauges you need.
Man, it's been a long time since I owned that as I bought it new in '87. I definitely did like the EMGs over the Low-Zs. But I play metal, so you should take that into consideration.
I had an '87 SR800 in candy apple red. It was the first Ibanez I'd ever bought and I have purchased many since. I switched out the pickups for EMGs. I loved that bass. Wish I still had it but I dont..
Picked up an SR2400 in amethyst purple. Love the sound. I don't have any pics to upload at present but if you want to see some go to zzounds. They used my bass for their photos.
