Good utility device
This is a super useful box. It transforms impedance like a champ! Like plugging a dishwasher into a microwave, and they work in harmony. The color really pops and the font is super modern too, I stare at it all day. Everything Radial makes is quality.

Selling my Radial EXTC-SA Reamp in excellent condition. Works perfectly, just has a couple little cosmetic scratches. This is great for re-amping , and mixing using guitar pedals. Used in my smoke-free home studio. Comes with original power supply.
