But in a good way, this is how so many of those classic fx sounds have been achieved, really though the ultimate system is an LS-2 with 2 signal chains in parallel all in the loop of an X-Blender, that is the ultimate in usable bass fx, isn't that right Higgie.
I would look at getting a preamp in the Jazz over using an external preamp but that's just me, I went down that road and it was annoying to always have to take the entire board with me to get my tone.
