in short: this amp is everything it's cracked up to be and more! i keep thinking that this thing is so smooth sounding. the damn thing is all handmade down to the transformers. it's so well made that it's scarey. the thing came in a wooden crate that looked like a coffin for a toddler! the grinder mod on the back really thickens up the bass. unlike other hi gainers there is just not a trace of stridency. just fat rock tones. i think my od100 se is more versatile but a completely different animal. the head is also quite massive at a good 65 lbs for sure. i've been playing it thru 4x12 16ohm chinese greenbacks in a knucklehead rivera cab. not sure they are the best fit. the crate is also branded with a mako amps logo. my best description is that it's kind of like the difference between a production motocrosser and ricky charmicheal's or jeremy mcgrath's-everything just works better. you feel like you are playing an amp made for a rockstar. god bless american amp makers and andre solner (sp?)specifically for producing such amazing products.
