This is such a cool tool ! (and ..they're hand-built !)It lets you use any number of speaker combinations on stage or in the studio ..
As you can see, it is in mint condition.. I take care of my gear ..
From their website:
"The Z-Matcher allows you to match the output impedance of your amp to impedances of speakers and cabinets that are not the same as your amp output impedance. Matches 2, 2.6, 4, 5.3, 8, and 16 ohms amplifiers to 2, 2.6, 4, 5.3, 8, and 16 ohms speaker systems. Includes an extra output jack (parallel) and a balanced and unbalanced line out with a level adjustment.
This item is hand-built to order, to ensure the best attention to detail is paid to its construction. We build them one at a time, on a table - not hundreds at a time on an assembly line. This allows us to reduce the margin for error and produce an overall higher-quality product."
