My standard Trumpet Straight Mute is a B2: medium-shallow with standard resistance.
BUT, if you want more control: here are some options: With cup depth ranging from A to E, and resistance 1 (most restrictive) to 3 (most open), and resonator materials including aluminum, brass, copper, rosewood, and LW Fiber, these mutes give lots of feel and sound options. Get yours for the reasonable introductory price of starting at $49.99!
