don't dread it bud, 'shed it. practice - use this as an opportunity to grow.
every time i ever went to record, whether it was by myself or with the band, -every- -time- i ended up hearing how i was no where near as good as i thought i was, and after a bit of self abuse and depression

i practiced that much harder. in the end every time i recorded ended up being a leap in my ability as a player.
so if they're hearing extraneous noises and clicks in your playing on the tape, you need to take the time to clean up your technique. practice -hard-, and tape yourself - even with the internal mic on your computer. listen for those clicks and clacks - that's probably improper muting of open strings that they're hearing. you can fix that with just a little effort.
even if you do end up telling these guys to go pound sand, you'll still be a better player for it.
