I love this rechargeable tuner works great for my acoustic guitar i gave 4 stars because the first one the battery was

Great tuner; so glad that it's rechargeable and not battery operated; good in dark settings due to its brightness; easy to use; with or without amp works really well...does have to be a quite area to work (without other instruments/noise from drunks/ etc.

Useful, works in any situation and on all stringed instruments.

The guitar setting works very well
