Both the outside and inside of this unit look great! Heavy steel case, quality components, only a few hand soldered connections, transformer is securely glued to the circuit board. Nice diagram on top making it very clear how things are connected. Everything including the switches are CLEARLY labeled (in my opinion some aren't or you can't tell which position of the switch(s) engage a particular function). I like how the attenuation switch is reasonably well protected from getting bumped/changed during handling between gigs (some have push button switches that look like they could be easily changed by accident) Tested it and the attenuation switch operates smoothly with no noise or fussiness. Frequency response was measured to be 3 dB down at 5 Hz, almost no loss at 20 Hz; at the high end, less than 1 dB loss at 20 kHz.
