I'm old enough to have played though 360s, but am I old enough I'm losing memory: Weren't the 360s folded-horn 18's??
Amazing to consider his Weather Report stage rig, the pair of 360s, stereo thru the original blue-faced MXR rack delay. And yet the ultimate case of the sound is in your fingers.
I always go back to 'Byrdland' from Weather Report's '8:15' live album. The first time I heard the head of the tune he was playing in those thumb-side harmonics, it was like an aural UFO sighting: I heard it, but couldn't tell you what it was!
