This is the second installment of the EVO 900. Nothing drastic has really changed from the first. Both are simply amazing bass heads.

SOUNDS

Once I plugged into this head I immediately knew that i had a winner. The controls are a little confusing at first but after a few minutes you get the idea of how they constructed the unit.

The sub control are a little tricky at first. These are the controls under the basic EQ up top. I am referring to the drive, compression, and sub harmonics. Using these sparingly and wide open will give you an assortment of optional tones and various control over how the bass EQ gets thick or thinner or more distorted. You can really dial in overall tone that will better match your bass guitar and or the pickups that you are using.

OVERALL OPINION

These units are harder to fin now that they have the Evo 900 lll. I think you can find them under $700 on the used market. Not a bad price for the tone of this unit. This amp is much better that say a Gallien-Krueger or Hartke. This amp has a round tone that will fit in a metal band and a pop bubble gum band. The versatility is pretty much endless when it comes to fitting this amp in any band setting. I would recommend this amp to anyone searching for a great sounding bass amp that will fit any need you may have.
