Transperformance's Performer is a new high-fallutin' computerized guitar tuning system that guarantees that your guitar can be tuned, de-tuned, and re-tuned with the push of a button. Not only does it guarantee perfect tune, but you can also switch tunings mid-song or between songs without changing guitars. The bad news is this costs more than any high-end guitar. So if you aren't Jimmy Page, you probably can't afford this system anyways.
In that case, I would recommend either the Buzz Feiten tuning system, the Floyd Rose Speedloader system or if you just want to switch to alternate tunings, check out a Line 6 Variax guitar and the Line 6 Workbench software.
nar, similar analagies would be the electric toothbrush, the electric shaver, motorised bicycles, you can have the non motorised ones, but we humans are always out to make things so easy for ourselves
lol but think of it. its the solution to guitars that go out of tune oh-so-easily. there's an auto tune function i think that keeps your strings always in tune while playing. so no more tuning in between shows.
and btw the electronic toothbrush more effective kay. cleans dirt more effeciently
