his "acoustic tone" that SOOOO many people keep refering to as "weak" or somehow different from Jerry's previous sound was from a Mike Christian Tune-O-Matic Piezo saddle. It was an innovative (and invisible) bridge saddle system that ran six little wires from each saddle to a preamp which was blended with Jerry's electric buffered preamp system. This blend is also why from night to night the tone would sometimes change radically from VERY acoustic - almost jug band acoustic tones and back to the very usual electric tone we were used to hearing. I say it was invisible because the wiring was hidden under the saddles (which were direct replacements) and routed internally so there was nothing visible to notice.
Don't forget Mike, what you saw in 2000 isn't the same as 1993. The Grateful Dead was a traveling laboratory for sound. Things change daily, weekly, tour to tour, etc. I started Dozin.com in 96 and all my information came from interviews from Sievert's guitar player or from people within. I know you had the great opportunity to see these guitars up close, but 20 years later. To say never happened or it was never that way, I just have to disagree.

Blair didn't use very much of the hard-date info I provided him... a bit over-the-top in geeking I suppose, but imho its nice to be able to compare sounds from neighboring shows and know what gear differences you are hearing... ah well.
Although GD 10-9-76 and all subsequent GD shows through 1992 feature the Twin Reverb duos, its quite likely he continued using the Mk I's for side projects and studio stuff for several years. A Reconstruction photo (1979) shows the Mk I's onstage.
For February-March 1980 JGB shows it was a Mesa Mark IIA preamp
Always into MC2300 solidstate power.
Now, the piezolessness of Bolt was a bit of a surprise to me, because it certainly did sound as crappy and thin as a piezo for the last couple of years at GD shows. Oddly enough, during the JGB 1993 East tour, Bolt sounds like an amazingly toneful and warm electric guitar.

Both buy the creator and jer's,guitar tech. and severel others like eg.Brawer Actually after the stratoblaster was not blended as I plain text worded before. It was wired into acustom secondary input added to the opamp into a volume pot(variable db's into jer's hard set 6db orig opamp and could be raised as high as 14db from that it went to bridge dp104 north coil hard wired via together in series pup selector spst switches.. Just like a piezo proper acoustic guitar location, I believe it is a 1st gutar innovation still today and one of jer's favouritefeatyres especially for like lazy river.FOTD and Peggy-O,etc.
