I'm new to bass, been learning for three years. I totally dig the tone of a fretless and decided to get myself one. I'm just scared whether i should do it this fast. as it is a lot different i guess. now as my first fretless what should i go for? a SVM jazz fretless so that i can get well versed on a fretless before going to a 6. or should i directly go for a warwick rockbass corvette fretless 6.
