The Seinfeld Show "Fills"

[Bob Kagy]

What instrument is that that does the fills, or musical punctuation on the Seinfeld show?

Is that a guitar, bass guitar? Anybody know exactly what instrument, fx, amp is being used?

I've always admired the sound and succinct humor of whoever it is that does them.

It would be neat to be able to occasionally quote one of the lines using steel tied in with the song lyrics being backed.

Thanks, Bob

Moved to the music section, as it is a better location for this particular question.
