Tom Crown Gemini Copper End Galax Aluminum Both are straight mutes for trumpets. I bought the Tom Crown Copper End because of its good sound, but I never used it after buying it, preferring the ease of playing of the regular aluminum mute I usually use. I don't think there are any dents or scratches, but I apologize if I missed anything. I bought the Galax thinking it would be surprisingly easy to use, but I ended up using the regular Tom Crown straight mute, and I never used it after buying it. Both are almost unused. (You can tell by looking at the cork) I'm selling them as a set to organize my equipment. Please feel free to ask any questions. I may be away on a business trip for about a week. I usually ship immediately, but please note that it may take some time depending on the timing.
