Did you open the lid and point the mic inside? That's how I've done a similar thing, lots of felt and pedal noise but for my purposes that wasn't so bad. didn't pick up too much of my tutting and swearing over lack of skill
Kinda, I took the top and front panel off and pointed a condenser over my shoulder at the sound board. Realised afterwards that I’d left the variable pattern on the mic to omni, which was exacerbating pick-up of my breathing. Moved it closer and set to cardioid… much better.
