BOSS TU-3 Chromatic Tuner

The BOSS TU-3 builds on the legacy of the world’s best-selling stage tuner, delivering enhanced visibility, accuracy, and performance in the iconic BOSS stompbox format. Designed for live musicians, it features a smooth 21-segment LED meter with adjustable brightness and a dedicated High-Brightness mode that remains clearly visible even under direct outdoor sunlight.

Choose between Chromatic mode or dedicated Guitar/Bass modes, including support for 7-string guitars and 6-string basses. The Accu-Pitch Sign function provides instant visual confirmation when you’re perfectly in tune, while the Note Name Indicator clearly displays the detected pitch.

The TU-3 also includes Flat Tuning mode, allowing drop tunings up to six semitones below standard pitch. When engaged, the tuner automatically mutes your signal for silent tuning on stage. It can even supply power to up to seven BOSS compact pedals, making it a true pedalboard essential.

• 21-segment LED meter with brightness control

• Chromatic and Guitar/Bass modes (supports 7-string guitars & 6-string basses)

Le meilleur endroit si vous cherchez une bass/guitare Fender custom shop. J’ai découvert Gérald Musique via Reverb et acheter une Jazz Bass custom shop. Le service a été super. J’ai commandée une deuxième bass Fender Custom
Shop auprès de David et son équipe. Ils ont été très serviables et m’ont répondu et placé ma commande chez Fender en moins de 24hr. Les délais de livraison était de 12 à 14 mois, mes commande a été remplit 6 mois plus tôt que prévue. La communication aussi a été excellente.

Super service et super inventaire de produits Fender Custom shop en stock. Je recommande fortement Gérald Musique si vous considérez acheter une Fender Custom Shop.

This place rocks! I was looking for a very specific guitar all across Canada and I found it in this gem of a shop located in Quebec. The people I dealt with there, namely Eric, were absolutely amazing. Very accommodating and helpful. I would buy from here again in a heartbeat. The guitar arrived in Victoria on time, quickly, very well packaged and I'm not even kidding when I say it was perfectly in tune out of the case and beautifully set up. I don't think that's ever happened in all my years of buying instruments. Thank you to Gérald Musique!

I recently purchased a digital piano from Gerald Musique and I am writing this review because I was completely amazed by their exceptional customer service. The purchase was smooth and the delivery experience was amazing. I received excellent communication regarding delivery options, dates and times. Delivery was prompt and professional. I would highly recommend Gerald Musique and will share my experience many times because it was just that good. Well done Gerald Musique, you are awesome.

Belle boutique d'instruments de musique, matériel récent en stock. Très belle sélection de guitares (particulièrement les acoustiques et semi-acoustiques). J'ai acheté une guitare Gretsch. Le prix était plus bas que toutes les autres boutiques en ligne au Canada! À la livraison le propriétaire a pris le temps de me montrer des modèles similaires et quelques trésors de sa collection. Une belle expérience d'achat.

I took a chance buying a guitar online from this shop and it's by far the best guitar I own. Made in Canada beauty, the Godin Session 59T. The price was incredible as well as they took a very reasonable offer. Everything about the guitar was perfect including the carrying case it came in. Absolutely no complaints and I would love to buy from this shop again.

Mon magasin préféré depuis ma jeunesse, un service de qualité, des bons conseils, aucune pression d'achat, le staff prend le temps de parler musique, du matériel pour tout les goûts et styles. Une fierté familiale!
