As a techie, I sometimes need a smack upside the head to remind me that time spent learning how to use what I have, is more productive than mooning over new basses or other gear.
I've been running my ABZ in series mode 90% of the time, to get that big, fat low end. The trouble is, then I find myself fighting the extra scoop and zing in the upper mids. The next thing you know, I'm daydreaming about tube preamps, or a P-tone pickup for the neck position.
While tweaking my recording signal chain yesterday, I discovered that the "uninteresting" and "thin" sound of the solo'd neck pickup is no such thing.
If I roll the tone control back a bunch more than I do in series mode, then boost the gain on my amp to restore the lost level, the low end is just as full, but now the D and G strings sound more balanced in the upper register, almost like a P-bass.
The ironic thing, is that I have spent far more time researching/buying/borrowing gear over the last few weeks, than it took me to woodshed my way into the tone I was looking for.
I've had my ABZ for 9 months. If I spent more time playing it and less time on Talkbass, I could have discovered this "tone secret" ages ago!
