Dan Erlewine's iPhone Guitar Modification

Howdy! My name’s Dan Erlewine. I’m a guitar repairman, builder, player, and journalist who operates a guitar repair shop in Athens Ohio. I also work for Stewart MacDonald’s Guitar Shop Supply here in Athens and have been since 1986. At Stew-Mac I produce videos, write books, and work on tool design and product research.

Last week a fellow guitar journalist and media man Michael Newman asked if I’d like to submit a little something for the Fusion Gig Bag blog he was working on. “Anything you want about guitar stuff,” he said, “repair, modification, playing . . . whatever’s on your mind as long as it is interesting to guitarists is okay.”

I took Michael at his word because that day I’d just received my new Yamaha Silent Guitar which I’m real pleased with. I bought the steel-string version, but strung it with Savarez High Tension nylon strings (I’d played the classical version the week before and loved it but the neck was too wide). Since it’s a piezo saddle transducer, not an electric pickup, it worked great.

1) The reason I wanted the guitar in the first place was to plug my iPhone into it and play along with whatever I’m listening to. I made a few modifications to the guitar right away . .

2) I replaced the maple leg rest on the treble “side” with a maple piece fashioned to fit the same holes with what you see here: a combo leg-rest/iPhone holder.

3) I carved into the bent plywood side to expose the iPhone button for easy operation and quick rewinds . .


4) The holder is two parts, glued and screwed together.


5) It looks decent, but needs some maple stain and a coat of finish (or black lacquer . . . or both!).

6) Something else I did right away (and this will probably horrify many of you) was drill and install threaded inserts down the fretboard to hold the capos that I make. I’ve been doing this for going on ten years and I love them. I make the capos out of wood, aluminum, and use vintage cuff-links for thumbscrews. I love to play with capos, I just don’t like their clumsiness and the way they cramp my hand.

7) Most of my guitars have these capos — even my 1939 Gibson J-35. The two capos here are used in tandem: the wide one holds down the two outside strings; the second (narrower) capo is holding down the middle four strings. The effect is that the outer two strings are a whole step lower but they are capoed-down, not tuned down. That leaves some very interesting possibilities when playing in the G, C, D, and A chord shapes. It’s too complex to explain here, but all you need to do is by a rubber-sleeved capo (like a Shubb) and cut the sleeve short so it presses down only four strings. Then use it with a normal capo and you’d have the effect that I get. Once I tried playing this way I seldom play in standard tuning without the dropped strings.

The only problem with my Yamaha mod is that it’s a little tight in the gig bag. Say, maybe Fusion has a gig bag that’s just perfect for it!
