I actually have a pair of Bootzillas on my Jazz. They sound pretty good honestly. I get a real nice burpy tone. But I'm also jacking my mids, relying on my bridge pickup, and playing a little in front of the bridge. I get the tone I want, which is good. But like a lot of these guys have said, the coating on the Bootzillas is terrible. It took about 1 month for the string to stop "shedding" coating. It would leave behind reminents of white, which I would of course wipe away after I played, since I usualy wipe my neck when I'm done playing. But, if you don't want to wait to get a good tone, skip out on the Bootzillas. Might I reconmend a pair of TI's. I've found there strings really good so far. But I think my Powerbass's are almost dead

. I got them a little bit before christmas, so it's been almost 3 months.
