18 volt battery assembly – 4 Pin

"To hear the true sound of your instrument (and more importantly of yourself!) without sounding sterile, the Bullhead 1K is the best digital amp on the market!"

"I've been looking for a versatile amplifier that compliments the quality of my instruments and playing style. I love playing through my Trickfish rig! And as an added benefit, it's light‐weight and fits in the trunk of my car!"

"It's so crystal clear and punchy. It's the best sounding amplifier I've ever played through and that's no BS. It reminds me of being in a control room and hearing your bass through the Neve and some ATC300's. I'm stoked! It's great to have an amp that sounds like yourself, only a lot louder!"
