should I get a bass trem from Kahler for a 5 string? I currently have 2 basses, one is Ibanez GSR200 which I have made fretless now... another is Ibanez BTB405QM, tuned E-A-D-G-C, and I would like to get a trem for this one. Ever since I saw Les Claypool do that intro for John the Fisherman with his Kahler trem, I wanted to get it... since I have only 2 basses, would it be too risky to sacrifice my perfect intonation, tuning, and tone on BTB405 just for some whammy abuse? how low or high can you go with a kahler tremolo anyways (one octave down/up?), and does it keep in tune well? any kind of advise will be appreciated, thx.
