For those of you still working on your recording tone for guitar (or for non guitar players looking for cool distortion effects) check out this deal Karzog LLC is having: their collection of Guitar cab impulses, Recabinet 2.0, which contains amp models from the 1950s to the present, which is usually sold for $70, is being sold for $15 for a limited time only (says it's a fall sale).

Being a rising rock/metal musician, I'm definitely picking this up. Mad props to Prince of Darkness for showing this to me.
EDIT: For those who don't know how to use these, you add a special VST that uses these, such as KEfir or Voxengo Boogex, into your FX chain and load the cab impulse you want to use there.
