There was a local band here that were doing original fusion/jazz about 10+ years ago. The bass player was using a 6 string, what else. When he played slap bass, his tone was not harsh or the typical slap tone, but was very smooth and percussive. I saw him play live several times, but never noticed what effects, if any, he was using. For awhile he played a Yamaha John Patitucci bass and then switched to a custom made bass. I believe he was using an Eden combo. His tone was always the same. Also the higher notes were not twangy, but very sweet sounding. I have not found a way to duplicate it. Is it heavy compression or something else? How about it my fellow TBers, any ideas? Here is a link to a windows media player file. Hope it works.
