Thanks for the replies! Yes it's an epiphone EB 3, I've had it a few years now, been fairly happy with the sound I get from it, nice and meaty, plenty of bottom end, but recently have been trying to refine it slightly hence trying to blend a bit more definition from the bridge pick up. The situation I mostly play in is at a church, 'silent stage' quality front of house and iem's so I've never had the need for an amp, hence the recently purchased Dr J sparrow di/driver, to add a bit more tonal options!!
I was just really wondering if this was an issue with my particular bass,<that could be sorted) or just one of those 'characteristics' of the instrument generally!
Oh and thanks Jus, I'll give that idea of starting from 1/2 way a go.
