Have you ever noticed any instance of your choice of instrument in a particular situation making you play something completely different than what you'd play with something else? For instance, I came to band practice yesterday with my fretless, because it's my main bass now -- I barely even thought about bringing my fretted, especially now that I've coaxed a good slap sound out of the fretless. When I pulled it out, one of the two guitarists said "Why'd you bring your fretless?" with a weird tone in his voice -- I ignored (he'd never actually heard me play it before last night). We started bouncing ideas and jamming and stuff, and the other guitarist kicked off this really mellow funk riff. He went through it a few times and the other guitarist joined in, and I found myself doing these really relaxed, legato slides around the chord tones that fit the music perfectly -- something that not only I very much wouldn't normally do on my fretted had it been there, but something I COULDN'T do on my fretted. I find that I also seem to play with less attention to technique (both left and right hand) with fretted when I'm playing fingerstyle and slap, and I tap/use chords a lot more on it. It seems on fretless, I'm much more aware of my playing overall -- I have to be, to intonate correctly -- and I find myself playing smoother, less chops heavy lines. Also, did anyone read interview with McCartney where he said that his more melodic playing resulted from playing the Hofner, because it was so small and light, that he felt more free on it? He also said that when he played a Fender, because it was so heavy and big, he played "just bass." I'm not sure which magazine it was in, either UK BG or BP. Any of you experience similar things? I'm especially curious about those who play both ERB's (6+) and 5/4's, and people who play EUB/URB.
