I'm playing a 1965 Vox AC50 head through a 1965 Vox AC30 Cab equipped with JBL D120F speakers using a Nordin Comet Krystin guitar and it's about the closest I've gotten to the Zeppelin 1 tone. Now, Jimmy Page used a Telecaster (and a Flying V) on that album, but I think this comes close to. Next time I'm gonna add the Tone Bender too to get the right attack and bite.
