JB’s Harp Box is an all-tube 16 watt amplifier specifically designed to
enhance the frequency response of your harmonica. Working very
closely with Jeremy “JB” Bustillos, an accomplished musician, BCA
designed this amplifier to be a versatile tone machine that defies the
status quo. Lower-mids and bass are enhanced to be tighter, more
present, and free from feedback and distortion. High frequency clarity
is strengthened and definition is ever-present. A harp player can use any
microphone desired, switchable pre-amp gain structures compensate for
even the hottest bullet mic. Front panel controls are: Hi/Lo gain switch,
Volume, Bass Boost switch, Tone and a clean Boost for soloing.
The Harp Box circuit is not limited to harmonica. With proper
adjustment of the Volume knob, acoustic and electric guitars sound
absolutely amazing through this amplifier. It is even suitable for bass
guitars in a low-volume setting such as rehearsal or the studio.
The Harp Box is a single-channel amplifier with Volume and Tone
controls. Available as a combo or head only.
Price starts at $1750 for HB16 Head.
