I love jazz, and I also like Larry Carlton. In fact, there is a radio statio here in Toronto that plays jazz 24hrs a day, 7 days a week (saturdays they a few hours of blues). That station is on every radio in my house, pre-programed, and on my car stereo! I probably own close to a 1000 jazz CDs. However, while I have a LSS, and love it, I don`t really play a lot of jazz. Mostly blues. Having said that, I used the manual as a guide, and then fine tweaked their suggestions on the clean channel, which is where your jazz is. Quite black face, as I'm sure you know. I don't know what else to add other than that. I suspect from posts that I have read here, that there are not a lot of jazz players on this forum. Replies to some questions can be slow.
