Bob Weir's McIntosh 2300
Early Grateful Dead Mac Amplifier used by Bob Weir
This is one of the earliest known Mac amplifiers used by Bob Weir of the Grateful Dead. Believed to have been part of the Wall of Sound and used at Watkins Glen, it is confirmed to have been used during the Europe '74 tour, as noted in the Europe '74 manifest, showing the designation "GD 010."
Details:
- Serial Number: 1Y348. This is the second oldest known Mac sold at auction, with the oldest being 1Y240 sold at Sotheby's.
- Unique Identification: While the serial number is not referenced on the back of the amp, it has always been identified as "GD 010." The serial number 1Y348 is stamped inside the chassis, suggesting the original exterior serial may have worn off or was never present.
- Historical Significance: This amplifier is likely one of the earliest MC2300 models acquired by the Grateful Dead. Evidence suggests it was used by Bob Weir as early as 1972, predating the Watkins Glen concert amps. Photographs show Bob using an MC2300 in December 1972 and throughout 1973, before the Wall of Sound era, during which Jerry Garcia was still using MC3500 models. The amp is believed to be the one seen in Bob's Wall of Sound rack, to the left of the drum stage, identifiable by a Playboy bunny sticker.
- Modifications: Like all Wall of Sound Grateful Dead amps, this unit was modified with banana jacks for daisy-chaining to eliminate ground issues, a lesson learned from Woodstock. It features an early ground jack with a red wire grommet, distinguishing it from later models. The amp was worked on by Dan Healy and Janet Furman.
