Review By: GGZR Rating: 5 Excellent Product: GuitarMan Mini Headstock Tuner Review: I have three of the 'other brand' mini headstock tuners which are very similar to this in size/shape/function. Saw the Guitarman Mini Headstock Tuner so thought I'd give it a try. It works great, tunes well, even has a rubber insert to help the clip grip the headstock. There is just one button on the back, which turns the device on. It starts at 440, then you can press the button again to cycle through to different frequencies if required. Hold button in for a second or two to switch off, then when switched on again it defaults back to 440. Screen shows blue when out of tune and green when in tune. Very pleased I tried this tuner, almost identical to the nearest alternative but considerably cheaper. Service from Guitarbitz was faultless as always.
