just me and my studio...drums, basses, guitars keyboards...way to much to list...but i do it all myself with the exception of drums on some tracks are beta monkey drum loops (there awsome get em!!! ) but since the addition of my yamaha electronic kit and countless hours of fine tuning..i am able to do the drums myself now and the sky is the limit with them running midi to trigger the drum module and software of my choice...my primary recording guitars are a carvin custom, with kahler pro trem...and a ibanez j-custom s3040pl a very rare guitar, but it dam near plays itself...
