I'm not really talking about keeping one guitar in Eb and the rest in E standard. I'm looking for feedback from those of you who keep specific guitars in a range of tunings. I play in a Stoner Rock project. At first I kept one guitar in D standard dedicated to our music and adjusted tuning as needed (i.e.. Drop C, Db, Eb). But that slowly evolved into keeping several guitars in various tunings we use. After getting a Non-reverse Firebird earlier this year and recently pickup up a new LP I've adjusted my line-up to cover more options and I'm just wondering what everyone else does. Before the new LP & Firebird: Gibson Les Paul R8 E standard / Drop D Gibson DG-335 Eb Gibson Les Paul Studio D standard / Drop C My current line-up: Gibson Les Paul R8 E standard / Drop D Gibson DG-335 Eb Gibson Les Paul R8 D standard Gibson Non-Reverse Firebird D standard back-up Gibson Les Paul Studio Drop C We don't play much that can't be covered by those. However, I recently tuned to Db and really liked how some songs sounded down a half step. So, now I'm considering dedicating my Non-reverse Firebird, which was my E standard backup, to Db tuning. Here's my new plan if I start write or play more songs in Db: Gibson Les Paul R8 E standard Gibson DG-335 Eb Gibson Les Paul R8 D standard Gibson Les Paul Studio Drop C Gibson Non-Reverse Firebird Db I've also been considering a C standard guitar as well. So is it silly to keep a guitar in each and every tuning or should I go back to just having E, Eb, D and adjust tuning on the fly? Does anyone else keep a broad range of tunings like this? I'm sure some of you must play slide or do the Keef open G tuning? What are your challenges or concerns? What does your quiver of guitars look like?
