When power is the only issue, slave out of your current amp into the SLAVE UNIT.
This amplifier replicates the tone of the primary amplifier's EQ settings. The additional
power volume is controlled by the volume pot on the front of the SLAVE.
Made in the same high quality standards of our GT-140 line, utilizing Hardwire and
turrett tag, point to point construction. This is perfect for PA's, Bass players and to
power additional cabinets with m o r e MATAMP power and tone for guitarists too!
