The Sound of Bass

Rock solid sound. This Baby will knock your socks off. The band just loves the tone. And it will certainly cary the volume out if your outdoors or full warm body in a small club. Simple, clean sound or loud and nasty. Your choice. It pushes my 4x10 and 15 cabinets just fine..

AMAZING SOUND!!! nice smooth bottom with good punchy highs. It's simply amazing. I paired mine with a GoliathIII 4x10 and I'm getting THE sound I've been lookin for!

Not happy with my sound, I decided to bite the bullet and buy the best. I did. I bought the 550X with Goliath-3 and Son of Bertha. It allows you the get unbelieable highs in snapping, and thunderous lows with the Sub-wave all in a user-friendly box. Keep it simple and that's what they did.

You might want a more powerful head, but from bars to festivals this head and cabinets have given me all the power that I need. Clean, crisp and powerful.

A great amp

i bought this amp and a Goliath III cabinet off of someone i used to work with (both in mint condition) before i even heard it. i've been using SWR for about 4 years now and this new addition is a blessing. as soon as i took it home and plugged it in the tone and especially the clarity just blew away my Workingman's 15" combo amp. and it's LOUD. i only have the volume set at like 2 because any louder and my band members complain that i'm drowning out the guitars, and i'm only pumping out 350 watts because i'm plugged into an 8 ohm cabinet!!! i can't wait to add another cabinet so i can get this baby pumping 550 watts and really p!ss off the other guys :) my only complaints are it'd be nice if it had it's own transparency knob (i'm one for lots of brightness and twang) and i'd prefer a distortion effect instead of the sub-octave.... i guess i should get the 750x then.

This amp is rocksolid, do you want tone, power, and definition? Buy this amp, pair it with a good cabinet, SWR, Eden, or similar, pick up your bass, close your eyes, and let it blow you to heaven.
