Hey guys, so I'm a guitar teacher & I want to set up a modest recording studio for kids to use in my teaching studio. I've put a lot of thought into it & the building I'm in would just cost too much to soundproof... walls are thin and it's by a busy street, so I think my best option is just to go digital DI. Would also be nice so I can have an older kid recording in one room while I'm teaching in another. As of now the vast majority of my kids are into stuff that requires a good clean tone, so... that's my criteria and question--which of the modeling amps has the most options/tweakability/general quality of the clean sounds? Mainly looking at the Vox Cambridge, Blackstar Silverline, and Spark. Any insight would be greatly appreciated. Thanks!
