I've been thinkin' about it for awhile- Along with my classic, unbelievable vibe/feel/neck '69 P-Bass & MM Sterling (sounds SO funky it hertz!) I've had a yen for a fretless- Narrowed it down to a Rob Allen, which I think is awesome-HOWEVER- Today, while at the LA Bass Exchange, I played & had to have a Rick Turner RB-FL-4- I am lovin' it! More fun than sex almost! 1st-thanks to the former owner for keeping it impeccable (it's a '97) & thanx to Long at LABX for having this biz. Then thanks to Mr. Turner! Oh, man, it brings a new dimension to the sound, what a trip!! WHY did I wait so long?? Anyway, on a serious note, playing the fretless makes me think along more musical lines, using glissandos, etc- I become more focused on melodic aspects rather than "sharper" linear passages & lines on fretted- Gotta be very cognizant of position too! I highly recommend it! Ok, thank you for letting me gush for a minute- Now, I'm gonna play!!
