300-watt Bass Amplifier Head with 12AX7 Class-A Tube Preamplifier Circuit, EQ, Compressor, Sub-harmonic Generator, and DI

Put the power, versatility, and tone of an Ashdown amp to work in your own bass rig, with the ABM 300 EVO IV from Sweetwater.

Just wow.

By Rich L. from Glenside, PA
Music Background: musician show off lol

I love the sound of this amp. It's plain and simple everything I've put through. It sounds amazing. I have quite a few basses and they all sound great.
Lovely, warm tone and a lot of growl when you want it it also can be as clean as you would like it to be and the top end is dazzling. The bottom end is rumbling without boom. I have it going through 2 double 12 mark bass csabinets.
It sounds as sweet as it looks, and I couldn't be any happier.
