I kind of want to add a whammy bar to my fretless, but I really want to play one first and find more info. I keep seeing the Kahler 2400 being thrown about but this post http://www.talkbass.com/forum/showthread.php?t=53528&page=1&pp=20&highlight=kahler+2400 mentions intonation problems? thoughts? Is it worth it on fretless? Like, will i be able to dive bomb or is the string gauge really a giant inhibitor?
