Well made but......
Well made but not as loud as I would have thought as per the description but it gets your attention. Tone seems a bit off as well, maybe a diaphram issue?? Feeding with an onboard air compressor to a 3 gal tank and running 110-120psi. If I find someone with a decibel meter I'll update.

sounds good
Sounds nice but inlet seems to be tapped in 1/8 and 311 hand pull valve is 7/16-24.
