I once had a Reverse Jaguar: I didn't like the midscale (32" = hard to downtune it)
Then I also found it hard to get thru 17th fret (I can reach it).
Not that I'm there everytime, but it gets frustrating
I own an ESP/LTD Phoenix (almost a reversed Thunderbird) and, for sure, an Epiphone reversed Thunderbird Pro IV
I still got them
Not only they're both a full step downtuned (the Epi sports an Hipshot GB7 bass extender too: from D, G, C, F to C, G, C, F) but they're full forcin' neckthru mahogany (Thunderbird) and basswood (Phoenix) while retainin attack sustain and definition
The Reverse Jaguar doesn't
Plus you can save something investin' on the P/J Modern Player Jaguar (I had it too)... It sounds pretty good and it's very handy... and Koto body is a surprise!
