Ce micro a tendance à accrocher facilement les larsen sur une guitare classique. Il faut donc passer par une égalisation un peu restritive au niveau de certaines fréquences, ce qui aboutit à un son moins naturel que le son original sans micro. C'est dommage car à ce prix, on pourrait espérer des performances moins contraignantes.
