I am 63 year old semi pro bassist. I have played and hauled 2 15's, 6x10's, Ampeg, Sunn, Fender, Peavy, Marshall, Hartke since 1974! You name it. My latest bass amps I had a Hatrtke Kickback 10 and a Carvin MB12. Sound wise this Fender Rumble 100 blows them out of the water. It doesn't have 29 knobs like the Carvin. Wonderful classic Fender sound even the built in distortion is great! At at a mere 22 pounds I am now planing on giging into my seventies! 100 watt bass amp but it seems louder! Also has DI out so you if you need more volume! Sam Ash rep was great! Party on Garth!
