20461-R M22-0 3-Point Prototype

20461-R M22 3-Point Prototype

Beautiful blackface 3-Point prototype mandolin, red spruce top. This is the prototype, signed February 2004, 61st instrument Hans built.

Edited description from Acoustic Music Company’s online advert: “This is a varnish early florentine 3-point style Model 22 made with Bosnian maple and topped with Adirondack spruce. The instrument is a blackface,  Schaller tuners with ivoroid knobs, 1 and 1/8″ bone nut, fine sculpted ebony pick guard, scooped extension, flat fretboard, masterful fit and finish. Custom Calton case to accommodate the elongated 3 point body. This mandolin was the prototype (and is designated as such on the label) for this model.

From Mr. Brentrup:  “The 3 point mandolin was Orville’s original (circa 1908)  florentine instrument and is a very difficult build. It has a very different sound which is well suited to old time string band music.””

Hans said “Top is Italian spruce and back is sugar maple. It’s a little shorter in length and wider than usual. (The original owner) wanted an A that was loud and crisp with that big bottom end so we chose Italian to make it smooth and crisp and sugar maple to make it crisp and loud. The graduations are a bit different, and it has a 1-3/16” nut.

2007 M22L Hybrid F4

2007 M22L Hybrid F4, 14 fret neck and elevated fingerboard, simple JBrentrup logo peghead inlay, Italian spruce top, Bosnian maple back.

Hans said it has “the biting trebles associated with Italian and a big bottom end… stronger than the F4C type, and a bit more focused sounding…. very close (sounding) to my 4 yr old M22V (also Italian/Bosnian). The color is actually more red than the pix show, and there is that hint of orange and yellow in the center. You can see some of it on the shot of the side binding.”

On Hybrids:

“It means that they have a longer neck and elevated fingerboard like an F5, and of course, that means that the bridge is pushed forward a corresponding amount. Some folks’ hybrids are 15 fret, while mine are 14. Mine also have a maple neck instead of a mahogany. The M22 doesn’t stand for anything in particular, I just didn’t want to call it an F4.”

Hans said “Features are German silver spruce top, quilted bigleaf back sides and neck, varnish finish. The tone has that complex German spruce flavor in an oval hole…big bottom end, strong, and with that oval hole refined sound. Trebles are strong, but when played lightly have that delicacy that ovals seem to have. Very green and needs a lot of playin’ in.

The longer neck takes out some of the tubbiness that the short neck A’s develop with time, and makes a stronger sounding instrument. It’s braced with one transverse brace, and if you have seen my M-4C, I do a cherry also. BTW, the line in the stain on the back is actually fishbone in the wood, and is mirrored on the other side. Just isn’t visible from the pictures.”
