This TC Electronic PolyTune tuner works great. Polyphonic mode is a revelation. Brilliant battery access. Bright display. 2000mA power out for other pedals.
The PolyTune originates from the Thailand factory that’s also responsible for the beautifully made TC Nova and G-System products. It comes in a robust, space-efficient metal case and practical niceties include input and output jacks mounted securely.
There’s a 9V centre-negative mains barrel jack and, when using a suitably currented adaptor, the PolyTune also has a power output enabling you to daisy chain other 9V centre-negative pedals up to a whopping 2000mA (most pedals draw around 35-50mA), thus making it both your tuner and your power supply.
The large display houses 109 tiny LEDs to light the various functions. We’ve used it at pub gigs, on a very brightly lit concert stage and at an outdoor daytime gig with no visibility problems – the LEDs dim automatically in low light conditions and get brighter when there’s more light.
The PolyTune features true-bypass switching, meaning that when it’s off, it’s completely out of your circuit and won’t affect your tone.
