Hey Jazzyvee,
I string my SC deluxe with 30-90. I like the lower tension these give me, because it enables me to pull off some nice triplet pulls and thumps that are tricky with higher tension strings. And I really don't notice any lack of bottom end as a result of using this string gauge on my Alembic, although I do on other basses, such as my Stingray. I guess Alembic's electronics and wood choices more than compensate for any loss of bottom end.
