Hi there, long time lurker, first post, and i do not know whether it belongs in the string or in the live sound section. Anyway, here goes: I have been playing guitar for years and started playing bass last summer and am now exclusively playing bass, mostly at church, and mostly because we had no bassist in the P&W team, but I am now having such a blast I do not see myself playing guitar with the P&W team for quite some time. I started with an epi EB-0 which I slapped some chromes on, and then bought a Vintage by Wilkinson 5 string Stingray copy (bought it from a UK store). I immediatly put chromes on it and liked it a lot this way. Come my Xmas GAS attack, I bought a second-hand squier VM jazz bass fretless, which, much to my delight, came with chromes, and sounds like heaven. I then decided to have a go at rounds and put DR Nickel low riders on the 5 string. I found I lost some thump but gained serious stingray growl and punch, while avoiding obnoxious highs. Me likey. I like the low riders tension, and feel the B string is a bit more defined that its "chrome" counterpart. The thing is, I tried it with the worship band at rehearsal, and have had a hard time eq-ing it correctly with the sound guy. We were running short on time so I played with the fretless and flats, but with the rounds on the fiver there seemed to be too many overtones resulting in some uncontrollable low frequency feedback. I am sure there must be a way to use my fiver with rounds on it and still get a good mix (obviously). Any ideas? Where to start? Are there some frequencies I should target and cut? It is difficult to describe but it seemed that there was still some kind of "reverby" low end resonance (for lack of a better description, my apologies for my limited pidgin English) even when I stopped playing and stopped my strings from vibrating... Thanks in advance!
