Hi Steve. I tried an 845 once when it was still in production but it had the BH2 Barts which really wasn’t my thing but,what's interesting is the replacement 945 has Nordstrand Big Single pickups which IS my thing. I'm wondering if the sheer body size along with the longer scale length and possible marketing towards the metal genre has made them somewhat niche 🤔 Don't rule out the 705 however as in my experience it almost played itself and sounded good doing it.
I've noticed Ibanez have removed the 705 from their website now.
