Questions: Amplifying Flattop Bass

Questions: Amplifying Flattop Bass

by Harry Fleishman

Mark Brantley of Appleton, Minnesota asks:

I recently ordered Tim Olsen’s plans for the Flattop Bass (GAL Plan #13). Do you have any advice on a good electric pickup for it?


Harry Fleishman of Boulder, Colorado responds:

It’s difficult to offer too much advice about amplifying your acoustic bass without more input about how loud you need to play, how high a fidelity to the instrument’s actual acoustic voice you want, and what your budget is; but here goes anyway.

Questions: Guitar Air Cavity

Questions: Guitar Air Cavity

by Art Davis, Alan Carruth, and Joe D. Franklin

Originally published in American Lutherie #63, 2000 and Big Red Book of American Lutherie Volume Six, 2013



Tom Blackshear of San Antonio, Texas asks:

Is there a formula for measuring the air cavity of a guitar box, then figuring out how to keep the same amount of air with slightly different box dimensions?


Art Davis of San Diego, California responds:

Use bird seed. It’s not totally accurate but it’s easy. Pour it in, pour it out, and measure it. Hold the guitar really well because ten or twenty pounds of bird seed is heavy. Also, as per W.D. Allen’s, “Basics of Air Resonances,” in The Big Red Book of American Lutherie Volume 1, changing the air volume doesn’t always do what you think it’s going to.

Meet the Maker: Henry Stocek

Meet the Maker: Henry Stocek

by John Calkin

Originally published in American Lutherie #62, 2000 and Big Red Book of American Lutherie Volume Six, 2013



There is a host of nonluthiers without whom lutherie would suffer. I refer to the makers and suppliers of the products that eventually comprise our instruments — the wood, trim items, pickups, cases, hardware, and finish products that make instruments more functional and more interesting. It should come as no surprise that most of these folks are as fascinating and dedicated as any luthier. We’ve met a few of them in these pages before, and I hope to give more of them the exposure they deserve.

First up is Henry Stocek, the celluloid guru who introduced us to the art of turtleoid creation (see Reinventing the Celluloid Tortoise). He created Deep River Vintage Instrument Supply to furnish the trade with imitation tortoiseshell pickguard stock that was reminiscent of the color and patterns used in the ’30s. Other items are on the way.

Matty: The Merchant of Greenwich

Matty: The Merchant of Greenwich

from his 1979 GAL Convention lecture

by Matt Umanov

Originally published in Guild of American Luthiers Quarterly, Volume 7 #3, 1979



I’d like to say that I’ve never given a lecture in my life; the last time I stood in front of a blackboard I had to write my name a hundred times. Perhaps a little self-introduction could explain to you some of my qualifications for being here. I have a store in Greenwich Village, where we sell, buy, trade, and repair quality acoustical instruments. I have had the store for 10 years, before which I worked sort of free-lance doing repair work on my own. And before that I struggled through a couple of different guitar factories.

People today generally prefer a Martin Dreadnought, usually a rosewood one for a bluegrass band. Rosewood is chosen over mahogany because of the richness of the tone; you get a much fatter bass out of a rosewood body guitar than you will out of a mahogany guitar. It is usually easier to record a mahogany guitar in the studio. Engineers tell me this all the time. All the extra overtones of the rosewood guitar are just too complex — it’s difficult to capture.

Flamenco Capo

Flamenco Capo

by D. Alfieri

Originally published in Guild of American Luthiers Data Sheet #46, 1977 and Big Red Book of American Lutherie, Volume Two, 2001



Start with a block of ebony 2 1/2" × 1/2" × 1/2". With a jigsaw, rasp, and sandpaper, cut out and shape (see drawing). Drill a hole through the center of the block and taper with an appropriate-sized reamer to match a violin peg. The size of the peg should relate aesthetically to the guitar.

Drill a 1/16" hole at a 115° angle on one arm. Notch the arms as shown with a fine file.

Inlay is optional. A bit of holly veneer dyed red with a red nylon string is a simple, but nice touch.
