Just got it today!!

Comments about SWR Classic Series SM-1500 1500W Bass Amp Head:

Although I am still waiting for the megoliath cab to get here, i got the head today and have played it through my halfstack. This amp is out of this world. You can dial in any tone you want! I play death-metal music and some classical on the side. Even though those are very different styles this amp really gives you the option to figure out your settings for any tone that you desire! I came across this piece of gear while trying to find something stage worthy at a professional level. I then read about this product and then I saw that Alex Webster from Cannibal Corpse uses this. He always has an amazing tone so I figured I could find my own tone out of this as well!! Very happy with this product!
