Like most pedals, the HT-6 can run either on a 9-volt battery or with an optional AC power supply. And as with many of the more competitive pedal tuners on the market, the HT-6 can provide up to 1000 mA of power to other pedals in your signal path. Two thoughtful inclusions for players who gig a lot are the glow-in-the-dark sticker for the footswitch and the hook-and-loop pad for easily adding the HT-6 to your pedalboard. You can tell the engineers at HardWire took a lot of time to think about the design of the HT-6’s display.
