This wild trapezoidal flatback four-string is said to have more volume and sustain "than any acoustic bass in the known universe"

Bass guitar veteran Troy Johnson spent a number of years touring with Ratt frontman Stephen Pearcy, among other artists. During his travels, particularly a mid-oughts acoustic tour with Pearcy, Johnson noticed what he felt were a number of deficiencies in the acoustic bass guitar market.

Though he enjoyed playing the Washburn AB45 he used for the jaunt, Johnson was left uninspired by its performance when not amplified.

After watching his friend, John Hargiss of Hargiss Stringed Instruments, build a harp guitar while making a resonator for Johnson's banjo bass though, inspiration struck.

"I would go from the upright, to the guitarrón/mariachi bass and the harp guitar, plucking and listening," Johnson said. "I then drew up a trapezoidal flatback body with guitarrón/Ernie Ball Earthwood dimensions, and an extended harp arm that connects to the headstock, almost creating a small grand piano.”

The bass features a top, back and sides made of 2-ply birch, and a 34” scale maple neck with a rosewood fingerboard. It can be played with a guitar strap, or with an endpin like an upright bass.

The bass can be ordered either fretted or fretless, and comes packing a K&K Twinspot pickup and with a gig bag included.

At the end of the day, The Big Johnson Bass – according to its inventor – "has more volume, sustain, durability and playability than any acoustic bass in the known universe." 

A steep claim, no doubt, but one that we'd love to potentially examine with the scrutiny of a demo someday.
