XO / JUPITER Trumpet Gun Grip Bottom Cap Used, one-owner (me) item with lacquer finish. This is the 【S size】 (B-1). A gun grip bottom cap is a longer cap designed to make the bottom of the trumpet easier to hold. Attaching it changes the ease of holding and the playing feel. There are various sizes, but the 6 in the photo are the last ones. First come, first served, thank you. ※The last photo is a reference photo with a different gun grip attached. This is not the product being sold. ⚫︎The difference between the A series and B series is only the color of the lacquer. ⚫︎The shorter the overall length, the less the playing feel and resistance will change. ⚫︎The longer the overall length, the easier it is to hold from the bottom, but the playing feel will have stronger resistance. ⚫︎Longer isn't necessarily better. The recommended sizes are 【S size】 or 【M size】. If anyone is interested, please let me know. Thank you. m(_ _)m
