GFB Whistling Trumpet (suits all valves)The 5702 can be used in place of the standard trumpet on all GFB valves, and will make the whistling sound more readily than the 5701 (high boost and RPM is required to get the whistle from a 5701), and at a slightly higher pitch.? Like the 5701 however, it is necessary to run the valve so that all (or most) of the air vents through the trumpet ? Respons valves will typically not generate the velocity required to whistle when set to 50 50 venting.

Cute - change footbed please
Size: 8.5, Color: Dense Smoke
These are so comfy and fit my usually 8.5 foot great. It's the footbed of UGGs that I keep hoping they'll change. It's like our memory foam mattress - cushy and great UNTIL THE HEAT comes! Then it's a no for this hot 65 yo G'ma!
