I bought the bow from Lefty 4 (Thanks again!). As stated, I have two Gharings. One is a longbow, one is a static recurve and both are one piece bows. They are really fantastic bows. They shoot great and the craftsmanship & attention to detail that went into building them is evident.
Neither of my bows are loud. In fact, static recurves generally have a reputation for being quieter than standard recurves. My understanding is Gharings were intended/built to use B-50 or B-55 strings. I believe (but can't guarantee) the bow you are looking at should be quieter with B-55 and yarn.
You might also have a brace height issue. About two years ago, I ran across Jon Gharing's son-in-law online. He indicated a brace height much lower than the one I was using. Regardless, mine was shooting very quietly and accurately. About that time, a couple of newly made Gharings became available online. I am not completely sure if these were made by Jon Gharing or the son-in-law, but this second resurgence never took off.
My recommendation is to look the bow over carefully, if you see no flaws and are impressed with the attention to detail, it's probably worth buying. Remove the rubber limb silencers, try a B-55 string and adjust the brace height. Don't pay too much for the bow either. Although they are really nice, most people have never heard of them, so the market for them is kind of variable. Good luck. - John
