John Campbell

“I ended up recording our last record on my ESP Stream, it’s a phenomenal bass. I pick it up and the comfort is immediately there. It’s like it wants to be played. I’m trying not be cliche here, but I fell in love with this bass from that moment."

“I like that the Stream is a unique shape. It’s not just another bass. It has some character. Most of the time, when basses get odd shaped, the weight balance is terrible. This bass is incredibly well balanced and ridiculously comfortable. It’s a joy to play this bass.”
