Production of this instrument ceased in 1974, resuming a few years later under the direction of Ernie Ball's employee Dan Norton, who still works for Ernie Ball Inc., until production finally ended again in 1985. The Earthwood acoustic bass guitar was quite large (and deep) in contrast to most instruments in current production, which gave it more volume, especially in the low register.photo 1photo 2photo 3 The Ernie Ball company describes Ball's design as "an idea before its time"; the instrument was little-used in acoustic musical performances until the late 1980s, when the acoustic basses were used in performances on the MTV Unplugged

 of acceptable volume at lower pitches on the low "B" string. One solution uses the five string acoustic bass to add an additional high string ("E-A-D-G-C") instead of adding a low "B". Another solution is to rely on amplification to reproduce the low "B" string's notes.
There are also semi-acoustic models fitted with pickups that are intended to be used with an amplifier. The soundbox of these instruments is not large enough to amplify the sound; instead, it is designed to produce a distinctive tone when amplified, similarly to semi-acoustic electric guitars.
