This amp is great I sold my LH500 to Sam Ash because I wanted the built in Compressor, and the shape and gain which is built in this amp . Very compact , and lots of power . I've read where people said this amp isn't loud not true . You must turn the gain on at least 3 then the master volume shakes the neighborhood. I love it , and I assure you it's louder then the LH 500 . Great for metal or if you like the funk it's excellent. Very versatile for any genre! Sam ash ordered it for me at store and conveniently shipped to my home .
