Most studios have musical instruments be it a grand piano, guitar cabinet/head, whatever. I've got a couple guitars, basses, some drum machines/samplers and a few classic synths. I was wondering if there are any sort of standard musical instruments that most studios have that clients would expect. I'm thinking along the lines of something like a workstation synth, or drum kit are maybe specific guitar amps. Recently, the work I've been doing has been passed along to me from other studios and I've run into a glitch here and there not having the same equipment as some place else. Aside from instruments is there any specific gear (aside from NS-10s) that a studio should consider getting? On the top of my aquire list is a B3 and leslie. More for personal use but it would be nice to have one in the studio for whatever.
