i have a Crate 18w amp that is basically exactly the same as this http://guitars.musiciansfriend.com/product/Crate-V-Series-V18212-18W-2x12-Tube-Guitar-Combo-Amp?sku=487055
but with only 1 speaker

How should i adjust the Gain, Level, Trebel, Middle, Bass, and Reverb to get the closest sound to as i lay dying or killswitch engage. (i realise it isnt an amazing amp and that it cant get the same sound, but i want to get as close as possible)
Numbers are in reference to an hour hand of a clock.

Bass 12
Mids 10
Treble 1

Gain 2

Use the bridge pickup.
