"Nice Amplifier / Loud Fans"
Overall: 4 out of 5 stars
Verified Customer zZounds has verified that this reviewer made a purchase from us.
Good, solid amp. I like the simplicity of it. The rear ins/outs are pro-level. My only issue is that the fans are extra loud. If you're on stage, it's not an issue. But, in a home studio, you will notice the noise.
