more improvisation help....

[slapnpop]

wut r some good scales to improvise off of for funk. especially slap bass lines.

[DocBop]

Same choices you have for Jazz or Rock based on the chord family. But remember Funk is all about groove including soloing. Listen to Marcus Miller or Victor Wooten when soloing they keep reestablishing the groove it never stops.

[Agilulfo]

A commonly used scale is the minor pentatonic.

[jackthestripper]

yep, blues scale too though they're about the same.
