I'd have to say my two favorites at this time are my current bass
Ibanez SR505 5 Strings
And the Warwick Corvette Standard as well but not fretless. I haven't played one of those yet
I love the tone in the Warwick's wood. I went to a Guitar Center and played a few of those and believe when I say they rock. You can get the sound texture and tone that you look for by playing with the controls.
Yeah i played a warwick corvette for around a year. borrowed until i bought my ibanez and it was gorgeoues to play. I want some kind of fretless in my rig soon so a corvette would be quite nice i think. the ibanez and warwick complement each other pretty well imo.
