Not trying to yank your chain but bear with me. You said this:
For the record Marcus has a Stars Guitar preamp in his Jazz not a Sadowsky preamp.the misinformation comes from Marcus having Sadowsky early in his career do repairs and some modifications for him.at the time Sadowsky didn't even have his own basses or for that matter his own preamps.
Marcus has said he has a Bart preamp. You just said the Bartolini came a "little later"...
So what does he have in the bass now?
Just want to make sure I'm following this
