Squier Tele Custom Baritone BK

You should always tune your guitar by comparing the twelfth fret harmonics with the twelfth fret fretted to double check intonation.

This guitar has major intonation issues because the bridge saddles for the strings pairs two strings preventing adjusting the length of each string individually. It's a shame because it could've been a great guitar if not for the bridge.

Buy a better baritone with bridge saddles for each string even if it means spending more money. Thomann has better baritones than this one for cheaper.

Google Fender intonation 101 for more information on intonation issues.
