Henriksen JazzAmp 112-ER 2015 Black (BluesAmp speakers)

Here is an excerpt from VINTAGE GUITAR magazine (Aug, 2013) reviewing the amp:

The JazzAmp series’ flagship is the portable 112-ER (Extended Range), which has an enlarged speaker cabinet to accommodate bassists and a switchable tweeter to enhance the response of acoustic instruments. Weighing in at 31 pounds, the 112-ER is housed in a compact 14″x15″x13″ cabinet. Eleven-ply Finnish birch is covered with tolex and reinforced with metal corners. The works are mounted on a steel chassis.

The 112-ER’s top-mounted controls include volume and five EQ knobs from 100 Hz to 10 kHz, each of which is “flat” at 12 o’clock. An on/off rocker switch (lighted when on), line out and input jacks, and a digital Reverb knob with accompanying slider on/off switch complete the lineup.

The back of the 112-ER has a metal heat sink, a power cable connector, and a tweeter on/off switch that’s mounted close to an upper corner to minimize the risk of damage. A speaker output jack allows for an 8-ohm or greater extension speaker, increasing the basic power of the JazzAmp 112-ER from 120 watts RMS to a hefty 160 watts RMS. A fuse drawer holds a 1.5-amp slow-blow fuse and a spare.

A front view of the JazzAmp shows the Eminence APT50 tweeter mounted at the upper right, a bass port at the upper left, and a 12″ Eminence Beta-A 12 speaker mounted behind an extruded metal grille featuring the JazzAmp logo. (Henriksen also makes a BluesAmp that features the Eminence Legend 1258 speaker.)

NOTE: The Jazz and Blues versions are identical except for the Eminence speaker. This amp is the Blues mod.
