A brief update on my Chromes adventure. I was practicing through my amp a few nights ago, and I notice that my tone was unclear and muddy, and passages over the 12 fret just weren't happening. I was really depressed, because it felt like someone had turned the 'suck' knob on my amp to 11.
Then, in a flash of inspiration, I put the TI flats back on my bass, and suddenly my tone opened right back up! Sustain was increased, clarity was better over the 12 fret, and the G string was less twangy. My bach cello suite was much more music. More to the point, the lowest notes on the bass were much clearer and better pronounced. I don't know if I just happened to get a dead A string on that set of Chromes or what, but the A on the TI is so much better for my tastes.
So, based on my experience with Chromes, and TI's, I am not sure if I actually like flats, or just TI flats which are very unique! I LOVE TI flats. They provide that amazing clarity but without grindy string noise that I am always striving for. Also, I was at a blues jam a couple of weeks ago and the house bass player had a 65 P with TI Flats, and even through one of those old, really crappy 80's Peavey 1x15 combo amps, he sounded really great!
