I've been listening to alot of solo/melodic bass lately - primarily along the lines of Victor Wooten. Particularly his Bass Extremes CD - I thought it was pretty neat to make an entire CD with pretty much nothing except bass and drums. Listening to this CD in particular, I noticed that usually Vic is hanging back playing a tight groove, and the other bassist playes the melody / solo line - which got me thinking that using a phrase sampler (I have the Loopstation XL), I could eventually learn to play some of this stuff live by myself, laying down the groove lines and then looping those and soloing over them. My question is kinda 2 parts. Firstly, does anyone have any recommendations on a great multi-effects pedal (or bass synth-type unit) to allow me to easily get different sounds to texture the music? I need something that I can customize to get my own sound, but it needs to be simple enough to operate (once my sounds have been set up) to be able to use on the fly, keeping in mind that I have the phrase sampler to operate as well, all in realtime. That probably means it needs to be entirely pedal/footswitch operated. Secondly (more of a technique question), does anyone have any recommendations about voicing on a 6-string with a phrase sampler so that the lines don't sound cluttered when I layer them? I've found in playing around with my phrase sampler that after 2 or 3 layers, I don't have much maneuvering room as far as my solo lines without cluttering the groove lines. Is there any special trick to this?
