Closest StoreLongueuil, Quebec
Après son utilisation lors de plusieurs basses à 6 cordes, il n'a jamais trouvé la note demandée. Il n'a montré aucun signal ou note. Simplement, il restait sans rien signaler. En plus, sa précision et vitesse d'accordage n'est pas remarquable. En comparaison avec un autre accordeur marque Profile, il est égal, deux fois plus cher. Fortement pas recommandé pour une utilisation professionnelle,
