Excellent product. One small drawback: Tuning low E on a Bass appears to be poor but you can easily get around this by fretting a higher note.
All LED readout of flat, in-tune or sharp (in 9 stages) and the note of the scale. Stomp switch to activate. Two outputs; one always-on the other muted when tuning. Uses 9v battery or external power supply (not supplied). Low battery warning (flashing LED).
Very easy to use. There is a Green LED for 'in-tune' the others are RED making it easy to use even in the dark. The functionality gives the effect of a continuous meter scale with each LED fading as the next comes on allowing very sensetive but quick tuning.
Metal case you could probably roll a car over. Get the idea ?
