I am going thru a phase... i am keeping the exotic boutique basses i own-- the Roscoe 6 and th F bass 5- but putting together a 70 style jazz 5 has awakened more desire!! so i am seriously considering putting together a fretless Jazz 5- two questions- 1- have any of you had any experience with stabilized wood fingerboards? i want the fingerboard to be very hard and resilient- 2- I am trying the j retro ont the 70s fretted- what would you use on fretless? bartolini? emg? i am trying to nail that j sound ( read, Jaco ) for all the newfangled basses out there- Jaco's tone on a J bass is unsurpassed- i know, i know, it was in his fingers.... but i realyl like that back pickup j sound- for the record the fretted has Dimarzio ultra j's- sorry if this has been discussed before- thanks for your help again-- peace, A.
