Thank you guys for all the replies !! Basschat is great.
My SR5 is super light (4.1kg) with most of the weight in the neck. It sounds great though.
Based on the info you guys provided and my own experience of owning a 1978 SR4 2EQ for years, I am leaning towards another SR5 but Alnico this time, as I fear a 2EQ will not cut through in every band setting
