Setups of The Stars - J.Garcia's Tiger

Guitar Player - April 1, 2001

By Gary Brawer

Jerry Garcia's guitars, built by luthier Doug Irwin, are as much one-of-a-kind works of art as they are musical instruments. I worked on Garcia's guitars for years, and I still get questions about them.
This guitar is called "Tiger" because of the beautiful inlay on the battery/preamp compartment cover. The body is made up of many layers of wood including what appears to be a Cocabola top and back with a maple center section (which may be hollowed out in parts). Sandwiched in between are thin layers of paduk, purpleheart, and brass. The maple neck has a hardwood section (possibly paduk) inlayed in the back and the ebony fretboard has brass binding.
Garcia played with high action--7/64" at the 12th fret, with .030" relief in the neck. At the nut, the strings a were also quite high at about .030" above the 1st fret. The ebony fingerboard has a 16" radius and sports. 105" x .45" frets. The neck and middle pickups are 10/64" from the strings, and the bridge pickup sits 14/64" away. (The bridge was made by Schaller for Gibson, and the tailpiece was custom made for the guitar.) The brass nut is scalloped between the strings, and the spacing--as specified by Garcia--is equal between the edges of the strings (as opposed to the centers of the strings being equidistant, which is more common). Garcia used Vinci strings, gauged .010-.046. but from time to time used an .011 on the high E and a .047 on the low E. --GARY BRAWER

Tigers Wiring

The aspect of Tiger I am most acquainted with is its electronics. The guitar features a single-coil in the neck position, as opposed to the humbuckers you see on his other instruments. Garcia used a DiMarzio SDS-1 Strat-style pickup in the neck, and DiMarzio Super 2s in the middle and bridge. There is also a coil-cut switch for the middle and bridge pickups.

The guitar's wiring is somewhat unusual. The pickups are switched by a standard 5-position pickup selector. The neck and bridge share a tone control, and the middle pickup has its own tone control. The output of the pickups goes directly into a unity-gain (no boost) preamp powered by a 9-volt battery. The preamp protects the guitar signal against high-end loss due to cable capacitance by lowering the output impedance.
From the preamp, the signal goes to an onboard effects loop switch, which routs the signal either directly to the guitar's volume control or to Garcia's effects (via a TRS jack), and then back into the guitar (through the same TRS jack) to the guitar's volume control. From there, the signal finally goes out the main output jack.

The genius of this wiring is that it allowed Garcia to keep full volume going to the pedals while controlling his output volume from the guitar. The advantage is that the tone and response of the pedals would not change with the guitar's output volume, as it normally would if Garcia plugged directly into them. The wiring also allowed for a true bypass of the effects when they weren't in use.
Many thanks to Garcia's tech Steve Parish for his years of trust.
