I have an Ibanez SR900 with the korean Bartolinis and I'm considering putting the the USA ones in. These seem to be the only other pickups I can put in there easily. Is it worth $200? Anyone try something in their Ibanez? I was also considering getting an OBP-3 Aguilar preamp. Any recommendations on doing pickups or preamp first? I just got a new amp rig so I think pickups would actually make a difference now. I was going to get an MXR Octave Deluxe and MXR envelope filter... but pickups may be more worth it. Playing through an SM-900 and Goliath Sr. now.
