There’s been threads on your single most favorite whistle, the one you’d want if you could only have one (on your deserted island). There’s also been threads on your favorite frankenwhistles. These comments fit into both of em’. It’s well known in the whistli’n community that Mack Hoover makes some pretty good whistles. (understatement) His whitecaps in particular are a great low cost way to “fix” an otherwise lousy whistle, especially if you’re like me and fond of a purish kind of sound. Like any hand made product though, there will always be some variation in the sound of any particular whitecap/body combination. I previously had two other whitecaps, and they have lived on Feadogs, Clares, Generations and a cpvc body that Mack made for me. All of the whitecaps seem to have a similar base sound with variations in volume, breath requirements and clogging tendencies. For those few people out there who haven’t tried one yet, that base sound is quite pure, non-breathy, with a slight reediness to it. The only downside of these mouthpeices (and this is allready well known) is the required precise, gentle breath control and the need to frequently blowout/clean the airway. Well to get to the point (sorry, rambling again) Mack sent me a whitecap to put on a Walton Mello D tube that had been gathering dust. I personally prefer the feel of the fatter tube which is the same size as most C whistle tubes. Also, the tone holes on the Mello D seem to be a little larger than most other cheapies, and a little smoother finished too. The Mello D like other Waltons has a laquer finish on it that is, well.. nasty. I soaked the tube in mineral spirits then rubbed it down with 600 grit wet/dry sandpaper with water. Now the tube has a satiny luster without being too shiny. The best part though is the sound… Oh I wish I knew how to post a clip of that sound. The larger bore of the Mello D in combination with the pure qualities of the whitecap just go together like… bread and butter, football and Sunday afternoons, Jekyl and Hyde… no wait, thats not right, well anyway the whistle just “gets it” (for me anyway) . There are no hard to hit notes from the bell note all the way up to the top of the second octive. It seems as though the slightly larger size windway on this whitecap does not clog as quickly as with the whitcaps for the 1/2" size tubes. (even those are manageable though) I had asked Mack to make this one with a low to medium volume and that is pretty much what it is. I played the Mello D side by side with my stock Clare D and the volume was nearly identical with the usual loudness above the high g, but not too loud at all. No whistle is perfect though and like other Waltons the bell note is slightly sharp. I plan on taking a hint from Jerry Freeman’s Mello dog whistle and adding a brass extension to the end of the tube. The C natural on this whistle also sounds almost perfect, pitch wise with a fingering of oxx ooo. All in all, I am happy to be " in remission" for the high D strain of whoa. Now I won’t need to save for the Burke I thought I would “need” to have. Gary Humphry’s Journeyman in B natural is tempting though… no, stop it, stop it Christmas is coming… I must think of others! sigh… 
DreamOgreen…I have a Humphrey B natural in brass…it is hands down
one of my favorite whistles…be good to yourself…order one…
do this for yourself…you deserve it.
