This subject seemed like a good opportunity for me to post a photo and comment. Hopefully the photo actually uploads. These are my go-to electric guitars. From left, a Ruokangas VSOP Supreme - Spanish cedar body, maple neck and arctic birch fretboard. Pickups are German Haussel P90. Guitar is like a Strat but way better. Second from left is a RickTurner Model One - mahogany body and maple top. Third is a PRS that Brian White expertly modified. I can’t say enough good things about his work. The guitar has a six-way switch...a topic for another day. Next is a Moriarty Wolf. Second from right is the real deal - a 13.5 Lb copy of Tiger that Gary Brawer and Danny Ransom built for me 20 years ago. They took 60 or so photos and a bunch measurements of the original while the Dead still had it. Inlays were done by Larry Robinson from his original templates from the 1970s. Last is a Phiga Tiger. Baby Tiger as it were.
Here’s the point of my long-winded note. All the comments here are relevant. I have a number of guitars that have the whole Jerry setup, and the one guitar that totally nails that 1980s low end grunt is the big heavy Tiger. I’m convinced that the sheer mass of this guitar is what makes the difference
