If this isn’t a great “Real Jazz Tone” I don’t know if it’s possible for the OP.
Up unto this point FSM gets at least a half dozen nice jazz tones from factory presets. The Dweezil Zappa 65 bassguy can do it.
Go to 12:31 minute mark. It’s Preset #61 (Fox ODS)
thank you GitGuy.
overall the tone is pleasant to listen, even if a bit dark or muffled (is this the right term?).
If you pay attention on the attack 'squeachy, crunched' sound that appears when he hits notes with more dynamic strnght;
now listen to the examples I posted: fast, steady attack, no crunch, no squeach, focus on sweet low mids, while highs are still there just rounded.
in short: what you posted is a cool sound, but not the sound I'm looking for.
When you play harmony with 'smoky wes' preset, you understand what I mean.
