Notable Features

• High input impedance (~ 500 kΩ) and output impedance around 100 kΩ — designed to preserve signal and tone, reduce tone loss.

• Mode switch lets it act as a clean boost (“Boost” setting) or into overdrive (“Drive”).

• Color control acts like a tone / filter control affecting brightness / frequency response, working somewhat opposite to typical tone knobs.

• True bypass switching.

• Solid metal housing; fairly large footprint for an overdrive — robust build.
