Jimmy used this guitar in the studio to record parts of “Stairway to Heaven”, together with another 12-string electric, a 1967 Vox Phantom XII. Later on, he used the Fender exclusively on the song “The Song Remains The Same” from Houses Of The Holy released in 1973.
I used a Fender 12-string in the studio. And before the Fender, I used a Vox 12-string. You can hear the Vox on things like “Thank You”, and “Living Loving Maid”. On “Stairway” I used both my Vox Phantom that I used on “Thank You” and my Fender Electric XII.
They both sort’ve sounded the same. It was more about how they played. They felt different. On “The Song Remains The Same”, it’s just the Fender.

Specs
The Fender Electric XII model was introduced in late 1965, and it was a purpose-built 12-string guitar with individual saddles for each string. The guitar had a Jazzmaster-shaped alder body, a rosewood neck with a “hockey-stick” headstock, and two split single coil pickups.
