Interesting...
The reason I brought this up is because I feel like I can stay on key better without cans - and struggle a lot with em'. Good to know I'm not the only one.
Also... I seem to find it easier to sing while playing guitar at the same time. I guess it just comes down to doing what's most natural for you - and not others, and if singing and playing at the same time w/o cans is natural - then an iso booth w/ cans and no guitar is very unnatural - to me anyway.
Great suggestions here - looking forward to using them.
