Probably a traynor ycv50 blue plus an eq pedal to scoop the mids.
I don't give a shit if you listen to me or not
They use special amps with DRM (Digital Rights Managment) so you can't record or download any of thier material.

Cheap alternative? A Boss Metalzone will probably nail that sound- Horrible amount of treble with no mids.
I can pretty much nail there tone using my Valveking with these mods and pedals, jj's in the preamps, mxr 10 band, bad monkey, isp decimator, ESP kirk sig with emg 81's and marshall 1960 cab.

But thats if you call close to $3000 worth of equipment a cheap alternative...

Whats your budget?
