You sit down to play, and your guitar sounds slightly off. The tuner you used to own is lost, or it needs a battery you don't have. Record Player Tuner from 123 Guitar Tuners is a tuner that listens through your computer's microphone and shows you how far off each string is.

Key features
A spinning record player that shows when you're in tune
The tone arm of the record player swings back and forth as you play. It settles in the middle when the string is in tune. It is a playful, retro alternative to a plain needle gauge.
Note detection from the microphone
Pluck a string and the tuner identifies which note you're playing and how close you are to pitch. You don't need a clip-on pickup or a cable.
No music store tuner needed
The vendor runs a set of online tuners that use your microphone. Record Player Tuner is one of several themed designs, so you can pick the look you like best.
Who it's for
It suits you if you want a quick, no-cost way to tune a guitar at your computer and you like a bit of character in the interface. It also works if you have misplaced your regular tuner.
Pros and cons
- Pro: free and uses the microphone you already have.
- Pro: a clear, fun visual of how close you are.
- Con: it depends on your computer's microphone, so a noisy room will make tuning harder.
- Con: it is a single-purpose tuner with a novelty design, not a full music tool.
