i think my wee desk is the folio notepad as well. what i have been doing today is putting a distortion effect in the FX send loops. on my mixer, the FX volume (global, not per channel) is up at max. With that done, I plug the mic into channel 1. The preamp and volume on channel 1 are normally up quite high (around 3pm), though sometimes the pre amp is less. With that, I usually twiddle the channel 1 fx knob to my taste, along with altering the distortion effect. for my distortion effect i was using a line 6 pod pro unit, but you can use anything, flanger, chorus, delay pedals, etc. make sure you are using a pop shield if possible. i've found that my sm58 sounds 100x better when using one for singing at any volume, though it doesn't matter so much for quiet stuff. my first attempt at a pop shield was double wrapped cling film with lots of holes poked in it, wrapper around a coat hanger. this was still way better than using no pop shield at all, i promise! hope that helps. in my experience, vocals coming straight out of my sm58 and into the desk sound quite boring unless it is a totally ripping vocal, which is why i often use an effect. oh wait, it could just be that my voice sounds like shit.
