Ibanez describe the SRXs like this
Muscular big brother of the SR series, the SRX is designed for heavier playing styles. The EQB-II DX 2-band EQ delivers a wide variety of sonic textures and the Ibanez PFR pickups are favorites among bassists who prefer a straight forward set up.
I think the necks are very slightly thicker than the SRs?
Thanks Hamfist
tell me please about the preamp too, I'm not familiar with this one. What are the specs, what do the pots do and is at all ok (no crackles, looseness etc)?
regards
