Gary Zimnicki - 1925 L5 Derivative Archtop [Sitka Spruce | Red Maple]

[iim7V7IM7]

I have decided to commission a guitar with Allen Park, Michigan luthier Gary Zimnicki.

It's All in the Details - Zimnicki Guitars

Gary builds archtop, flattop, Gypsy, nylon string guitars as well as mandolins and ukuleles. I have known Gary for over a decade now, meeting him and auditioning his instruments at the Artisan Guitar Show, Rocky Mountain Archtop Festival and Woodstock Invitational Luthiers Showcase. I have always found his instruments to be excellent, but never thought of the right project for him up until now.

I recently visited the Musical Instrument Museum in Scottsdale, AZ and saw a visiting collection of instruments called “Acoustic America”. Among that collection was a 1924 Gibson Lloyd Loar signed L5. This is architype American archtop guitar. I decided to have Gary make a 16” L5 derivative archtop for me. It will not be an exact replica but with be an instrument with a very strong nod to the Kalamazoo namesake with a couple of custom material and ergonomic features.



I was fortunate to get some good measurements on some vintage L5s and was able to get some photos of certain details. These archtops have asymmetrical parallel braces likely derivative of mandolins. The 1923-1924 Type 1 models had Birch backs and Virzi Tone Producers (elliptical spruce disk with f-holes suspended from the soundboard on three posts) which this instrument will not have. The Type 2 models 1925-1929 will be more what this guitar will be based on.

The Gibson catalog from 1924-25 stated “Sounding boards are carved from Adirondack, West Virginia, Norway or Pacific Coast spruce of the very highest grade and quality available.” This archtop top set is quartersawn, AAA aesthetic grade Sitka Spruce sourced from Alaska Specialty Woods (Craig, AK). Being harvested from an enormous old growth tree, it has incredibly tight grain structure and displays beautiful medullary array as a result of their sawyering. Sitka Spruce is a denser and stiffer softwood, on average falling in between Norway Spruce (Picea abies) and Red Spruce (Picea reubens).







The Gibson catalog from 1924-25 stated: “Back-boards are fashioned from the finest quality straight and curly grained Northern Michigan maple or birch, depending on the style and grade of the instrument.” The back and side set is a beautiful curly, AAA aesthetic grade fiddleback, Red Maple (Acer rubrum) that was originally sourced from American Specialty Hardwoods (Clinton, MI). Red Maple as one of the North American soft maples that falls in between western Bigleaf Maple (Acer macrophyllum) and European Sycamore (Acer pseudoplatanus) in terms of density, hardness and stiffness. We will use it for the back, sides and part of the three piece neck.

Instead of using traditional celluloid binding, Gary will use hardwood binding on this instrument. The guitar will have a Kalamazoo-esque Cremona Brown Sunburst, so we wanted to use a durable, hard, color contrasting, visually interesting hardwood for binding. We chose East Indian Satinwood (Chloroxylom swietenia). This a dense, hardwood light in color with beautiful, chatoyant figure.

This is going to be an amazing project.

Beautiful write up. Look forward to future posts.

If you can't afford the real deal, but can afford a bit more than a Loar costs I'm sure it'll turn out great, so very premature kudos!

Tuners - Waverly Individual Guitar Tuners with Pearl Knobs for Solid Pegheads, Gold

That must be the only faux pas for my eyes ... but there's time enough to discuss putting on matching wood knobs

GOOD CHOICE -- GARY ZIMNICKI

Some examples of Gary's labor of love from his exhibit at Woodstock October 2022 -- I love his guitars!
Purple Heart hardwood binding is beautiful on that superbly built natural spruce and maple single venetian cut-away.
And the stunning bird in the branch inlay in the headstock of the flat-top!
Gary's attention to detail is outstanding, and the build of his instruments, splendid.

Hmm, purple bindings on a blonde guitar is an acquired taste, but doesn't that wood turn brown over time anyway?

[iim7V7IM7]

We are still a long way out from Gary starting this project in earnest next year, but we came up with a headstock inlay design more based on a 1925 L5 with a horizontal logo vs. the angled 1923-24 logo. Again, this will be bound in Ceylon Satinwood and not traditional binding as its Kalamazoo namesake used.

iim's commission threads are one of the best things about the forum. And he has some dandies. I remember the 'Roycroft Rose'. I look forward to watching this evolve. All the woods look amazing. The satinwood binding will be especially tasty!

Yes, purple heart will brown over time. How much depends on the finish and the amount of exposure to UV light and oxygen. It happens quite quickly after cutting if it isn't protected. Then it slows under finish. It can end up a beautiful, deep brown with a touch of purple. Padauk (the orange one) does similar. This can be sped up by sun bathing, which also does nice things to spruce if you ask me.
