Think for a moment: every time you put your instrument to your lips, do you play fortissimo? Probably not. You play fortissimo, pianissimo, and everywhere in between. Dent removal is very similar. Let’s imagine you have an instrument with a dent in it that is made of thin soft brass and you were to flap onto it a 2″RAT. You would be creating more damage than you started out with. To eliminate the possibility of this happening, we do not sell the 2″ RAT to any technician no on file with us as having preciously purchased the essential tooling. You have to use finesse in MDR just as you would with a ball on a rod.
