5.0 out of 5 stars The Holy Grail of Bass Amplifiers, February 26, 2011

This review is from: Gallien-Krueger 1001 RB-II Bi-Amp Bass Amplifier (Electronics)

As with most bass players, I started with economy gear. I very quickly learned how dramatic a difference high-end gear can make in the quality of your sound (when I upgraded to a Gallien-Krueger 115RBH Bass Guitar Cabinet (400 Watt)). The clarity of the sound when compared to my first cabinet ( Hartke VX410 Bass Guitar Amplifier 4x10 Cabinet, 400 watts) was astonishing! I knew the same would be true for the amplifier, and this was confirmed when I upgraded from the my first amp (Hartke 3500C Bass Guitar Amplifier Head, 350 Watts) to this Gallien-Kruger 1001RB(II). It has amazing power, clarity, and flexibility of tone (which becomes increasingly important as you start to play with other musicians).

I feel like I have discovered the Holy Grail of Bass Amplifiers! Thank you Bob Gallien, for your original vision, and for all your many years of commitment to excellent and innovation in developing and producing quality bass gear beyond the call of duty. You have made the world a better place for musicians as well as all those who listen to music! I hope to eventually add the (Gallien-Krueger 410RBH/8 Bass Guitar Cabinet (800 Watt)) to the rig (when I start playing larger venues).

This review is from: Gallien-Krueger 1001 RB-II Bi-Amp Bass Amplifier (Electronics)

I'm a professional bassist in a metal band using a 5-string bass. I have a GK Neo212 cab bi-amped to this head for practice and can add a Neo115 cab also bi-amped to this same head for shows. I cut out the mids and use bass and treble gains only. I play with a pick and I love the 4-string/5-string button to add low frequency to my low-B string. I cut the highs out of the horns and woofers because I have active pickups on my bass. Do yourself a favor and try this head and you'll see that it growls just as good as any other head in the store. It's light-weight and goes perfectly with the GK Neo cabs for lugging around on the road. THERE IS NO BETTER HEAD FOR THE PRICE PERIOD! Flea and Duff McKagan use RB heads for a reason.
