Yes he did, and it was a human travesty.
Seriously, going direct thru a full-range speaker is a horrible idea if you want a good Jerry tone. It's a terrible sound, all that unwanted, glassy high treble just jabbing you in the ear with needles, no midrange harmonic character, no singing aluminum dustcap, just a perfectly undesirable tone.
I like to repeat this idea now and then. Acknowledging that Jerry's tone with the GD died in '93, basically from the late 60's till '93, there was ONE constant factor that largely defined Jerry's tone; the JBL 120 12" speaker. Sure we can find alternatives that offer similar characteristics, some better suited for low power guitar amps, some better suited for ultra-light cartage, but I still argue that the centerpiece behind Jerry's tone, other than Jerry himself, is the JBL.
A full range speaker is the antithesis. When we slam and saturate a JBL with all those strong highs, that sweet, tubey, sizzling, blazing treble, the JBL naturally rolls off the unwanted ultra-high stuff well above the "tone" range because of the natural frequency response limitations of the speaker itself and turns it all into a sweet, smooth, juicy tone quality some of which emanates from the resonant aluminum 4" dust cap. A guitar speaker also gives a voice, a midrange character, a coloration to the sound to the point that it's actually part of the instrument. But thru a hi-fi, full range speaker, all the character and dynamic response disappears and all we're left with is pure sterility, lifeless and soul-less tone. Run screaming from the EON powered PA speaker or any other full range speaker when going for a Jerry tone. That's a road less traveled for good reason.
The only case where the full-range speaker approach seems to work OK at all is thru digital modeling where the algorithm is emulating the natural speaker rolloff and saturation. But that's an entirely other realm than the pure, analog guitar "amp" approach thru the right tube pre and maxed power amp into carefully saturating JBL's.
