The tuning is plutt prcis I find as I compared with 2 tuners tuning APRS portable KORG DIFFERENT and I had nothing retouching.
But the default one is necessarily a price, the Casing plastic which will take care and be mticuleux with a. Same in regard to changing the battery, the Systm is really bad and the air of being the same for the pedals of the same size in the brand. Any fawn, do not count on using batteries, the tuner you empty in no time. I therefore used on my pedalboard with a multi-power.
If you want a tuner of this type for a fist fig, know that it is reliable but he must take care because it is fragile.
