Hey Jim C, sorry I didn't reply in the other thread. Just saw your question now!
Thanks Derek,
What other brands did you have in your bass, what amp, and what type of music?
I've played around with primarily Fender's Original Jazz Bass and the Custom Shop '60s in my own bass, as well as vintage pickups in others' basses. Compared to these, the J-45 has more fundamental, more clarity, better balance, and more easily translates changes in technique. Noiseless performance is a huge plus. I've tried offerings from Aero, Bartolini, SD, Duncan, and a few others, and was never in love. If I didn't find what I wanted in Bill Lawrence, I'd probably look into Delano's bladed designs, Villex, or Q-tuners, but the J-45's poled design gets me what I like from the traditional jazz bass sound with the full, extended sound I'd look for in a "modern" design.
I like clean, full tone, and until recently played through my studio setup at home to get a relatively uncolored amplification. In the past, I've used a variety of heads and cabinets from Ampeg, SWR, and Eden. I picked up a Genz Benz Shuttle 12.0 MAX when it came out earlier this year and play it through a Bergantino AE 210. Definitely a lot more color than a studio setup, but still sounds clear and full. I love the Berg but can see myself building greenboy's fEarful 15/6 in a month or two
I suppose I play rock, but I try to remain as versatile as possible for dense mixes involving layered effects, walls of distortion, or heavy varied instrumentation. I end up playing a lot of cello pieces on bass (cello is my "first language") and arranged piano pieces with friends on guitar. Translating nuances really helps with phrasing and contrast in general. I find having a clear tone with everything there keeps you from needing to turn up the volume or cut through the mix to be heard. Pretty optimal for my needs.
