Fast, bright, sleek, accurate and polyphonic, the TC Electronic PolyTune chromatic tuner is pretty hard to top. Even so, TC refused to rest on its laurels. First, it developed the ultracool PolyTune iPhone app; now it’s introducing the PolyTune Mini, which provides many of the PolyTune pedal’s features in a box that’s about half the size of the already compact original.

As anyone who has ever experimented with lots of pedals can attest, some of the coolest sounds are created by using two identical or similar effects together. Savvy pedal designers have exploited this phenomenon by developing stomp boxes that place two effects in the same box but provide extra flexibility and capabilities that two individual stomp boxes together can’t match. The Visual Sound Dual Tap Delay is a great example of this approach, harnessing the power of two independent delay units to produce effects that are greater than the sum of their parts.
