I don't notice a difference
Epiphone G-400 Ebony
Line-6 UberMetal, EchoPark
Boss RC-2 Loop Station
Traynor YCV50Blue, Bass Mate 25, Guitar Mate 15
The studio is much lower quality then the std. The std is a great guitar, if you have to get one used. I personally would not recommend the studio to anybody. For the small difference in price you get a much better guitar.
The Studio is built with lower quality parts than a standard is (bridge, nut, tuners, electronics, etc...)
For reasons I'm unsure of, where I live the Studio costs more than the Standard...
