ive played many Modulus basses, especially the jazz basses, or should i be Alan Partridge about it and say Moduly anyways they are so precise, every note is just there, incredible action, but i hate to say it... boring tone. its the graphite necked jazz basses specifically.. then i come back to a proper jazz bass, and everything seems easier tone wise. there not close to the playability of a VJ4 but i dont care.. the tone is there.... i know what you mean though.... you just cant beat a good jazz bass... but then there is Suhr who imo take jazz basses to a different level, even over sadowsky, alleva, imo..
