Hey guys! I'm in the process of buying an old Sadowsky NYC 5 string (ash body and maple neck) bass from a friend. It plays great, and I love the sound. The only thing I'm not 100% happy with is the fact that I'm getting a tad too much brightness when plugged in, and the sound feels slightly low on the low-end. It's equipped with two EMG 40J single-coil soapbars, which I understand are known for exactly that; "expensive" brightness and punch, while not delivering as much low end. I'd like to ask all you skilled and knowledgeble folks out there, what are my options in terms of exchanging these pickups for something a bit more versatile, and what do you recommend? What are some absolute no-no's when it comes to compatibility with wiring/pre-amps etc? Is it better to exchange the pre-amp at the same time for something else? Right now it's got the stock Sadowsky preamp installed. I've been toying with the idea of a humbucker/single-coil configuration, and I know Aguilar makes great stuff, so I've been peeking at their pickups. Thankful for any advice. Cheers!
