I need a tube amp I have narrowed it to a B52 AT-112 or a B52 ST-6012. (crate)

take into consideration the following:

I need an amp for modern rock like sevendust, chevelle,tool, blackstone cherry, etc.

I also need it to clean up nicely

I have a gibson les paul studio 1991(the good one with maple top)

Most of the stuff i do is in drop d or drop b.

also i dont need to know how unreliable they are,as i have often been told. I have also been told that these reliability issues have been solved as of 2002.

since i have a limited budget i didnt want to fully spring for the more expensive ST-6012 until i had some quality advice/opinions.
