Man, he was hysterical ;]
Released in 1961, rather avant garde in a certain respect, and you nailed it.
It's not electric "guitar" but rather Grady Martin's 6 string Danelectro bass, with hella distortion. This predates Satisfaction or whatever the usual commonly accepted 1st use of "fuzz" on a record by like 5 years.
Just heard this the other day and it blew me away. Grady Martin, Nashville session master, is credited with playing a Danelectro six string baritone...

My last Dano 6 string bass, or baritone guitar. Foolishly sold it, that was my 2nd one.
I sold it because it lacked the punch of my P Bass live.
