Re: SSL-1 vs. SSL-2: Big Difference?
This is something i've been coming to grips with recently, although with a brand other than SD. I have a set of strat pickups with staggered poles, and they've been in two strats that both have 9 1/2" to 10" fretboard radii (?). I can distinctly hear that the middle two strings sound louder. Angling the pickups up closer to the strings at one end or the other seems to just make the opposite side sound weaker and the excess of volume on the middle two strings doesn't really change.
However ....the pickups i am using are Alnico 3, and need to be set closer to the strings that A5 pickups would, so i have to wonder whether the A5 varieties would suffer less from this problem as they need to be set down further from the strings, and thus maybe the stagger has less effect ? I have A5 pickups in another Strat, but i bought them after discovering this problem, and so i ordered the A5's with flat pole pieces. I have also just recieved a duplicate set of the A3 ones, but this time with flat poles.
So...i have concluded that (for me, anyway)...any A3 Strat pickups should be flat-poles unless they are going into a vintage radius (7 1/2" or whatever it is), and i'm not certain about A5's, but i'd err on the cautious side and use staggered poles only on the vintage radius, flat for everything else. I realise some people may not hear the imbalance across the strings, or not be bothered by it. Because I need the slightly flatter board, i am going to stick with flat poles in all circumstances, but like i say, the effect may not be as bad with staggered A5's due to needing to set them further from the strings. I guess if you're in the USA you can try one type and have the option to exchange them, but if you try the staggered ones first, be sure to listen closely using a clean sound and preferably through a few different amps.
I hope i haven't confused the issue even more, hopefully others can contribute from their experiences...these have been mine and it has been a frustrating and expensive time getting it sorted out.
