FAQ
What makes this guitar so great for modern fingerstyle techniques?
So many things. Playability wise, it has a slightly wider string spacing, moving towards a classical guitar width, which makes intricate finger-picking easier, and complex chord shapes more accessible. The frets are a little taller, and made from stainless steel: This makes any hammer-ons or tapping much louder and clearer, without having to play so hard. And the tapped or slapped harmonics are more bell-like and musical. As a bonus, stainless steel frets last for many, many years without the need for repair or replacement.
And tonally, the body is large but still ergonomically shaped, so you get all the “piano bass” on the bottom strings, but it’s still comfortable to hold.
The scale length is also fractionally longer than you would expect on an acoustic guitar. This means that the bass notes have more “fundamental” (the lowest tone you hear when you play a note, rather than the overtones) and sound deeper and richer. But it's not a baritone or "long neck" guitar, so the difference feels negligible for the left hand, and the harmonics are still sparkly and lush.
Please explain the pickup system. Is it complicated to use?
Most modern players have been on a long journey experimenting with pickups, to try to find all the sounds they want to get from their instrument, which can’t be created using a standard under-saddle piezo you’d find on 99% of guitars with pre-installed pickups.
Magnetic soundhole pickups are wonderful for getting an even, reliable string sound, with the maximum volume without feedback. Then internal microphones are essential for finding the sound of the “air” - the natural acoustic sound of the guitar. And finally, body sensors, or transducers, give you the bottom end: Your low bassnote fundamentals, and any "kick drum" percussive effects.
This system unique Fishman have produced for the JGM has all three of those elements. A Rare Earth humbucking magnetic pickup, a Rare Earth condenser microphone voiced perfectly for guitar, and a PowerTap body sensor, mounted to the bridge plate (inside the guitar).
There are two output jacks, but if you want to keep things simple, you can just plug in one regular guitar cable into the guitar, and it will send all three pickup signals down that one cable. You can blend them using two little blend-wheel controls discreetly mounted at the soundhole.
However, if you plug in a stereo cable, plus a regular mono cable into the second jack, then it will send all three signals separately, so you can mix them how you like. Maybe add effects to your strings, but not your body/percussion. EQ everything just how you like it. This is how I and all my pro fingerstyle peers get our sound.
There's even a third option: If you have a two-channel amp, you can plug in two mono cables, and get the Rare Earth system in channel A and the PowerTap sensor in channel B. A useful compromise when you are restricted to 2 channels.
So, it's a simple or as complicated as you want to make it.
To have a system with this sound and this functionality pre-fitted into a guitar, is the holy grail.

Why is it better for percussive guitar playing?
Unlike my old guitar, this one doesn't need a reinforced top, because it uses that Thermo-Aged Sitka spruce. Thermo-aging makes it stronger (and sound amazing: It's like it's pre-EQ'd).
I tweaked the body shape so it's no longer symmetrical (which may be a first in acoustic design, I'm not sure), so certain common techniques are easier to reach. And the cutaway area is the perfect size and shape for any “bongos” and “snares” you wish to play down there.
The finishes have been chosen for percussive sounds too: The top is natural, non-sticky and woody, and the sides are gloss for a sharper "crack" on your snares.
I even moved the bridge. The bridge is offset, like a less dramatic version of what you might have sees on fan-fret guitars, to open up more space and resonance for the most common kick drum (aka bass drum) technique. Don't worry, the intonation is unaffected, of course!
How did you choose these woods?
After building the basic first prototypes, just to test the body shape and scale length really, Ibanez made second stage prototypes with a variety of woods and finishes. Then I blind tested them. I also took them home and tested them for weeks, making each one my main instrument for that period.
We tried spruce, Thermo-Aged spruce, cedar and bubinga soundboards. I love cedar, but it is so soft it isn’t really good long-term for percussive techniques, but it was a useful comparison for its beautiful tone. The Thermo-Aged spruce won hands down. The Thermo-Aging process is truly extraordinary. It gives the wood the character of a 20 or 30 year old instrument, but it has more strength, rather than less. Like tempering a sword, I guess! It still took a few weeks to settle, but after that, it takes away all that harsh newness which spruce has for many years.
The back and sides, we tried the more traditional mahogany and rosewood, but I just loved the Pau Ferro - It has the density and therefore the clarity and enhanced highs and lows of rosewood, but to me it has more character in the lower mids: A kind of darker, earthier tone. It also looks beautiful, with a reddish purple colour and often a highly contrasting grain.
Also, it’s a sustainable wood, which doesn’t require the decimation of ancient rainforest to harvest.
Where are the two banjo tuners you use?
So, I decided not to include them. Those tuners (Keith Tuners from Beacon Banjo) cost $130 each, and so it would add over $250 to the price, and I figured not everybody would want them. (For perspective, the best quality guitar tuners cost about $80 for a set of six: $13 each!) I don't want this guitar to be only for my fans. Also, if you want them you can buy them and install them very easily. All you need is a screwdriver. And $260. (There are cheaper copies available but they simply don’t work very well.) The Keith Tuners are an important part of my playing, but not an important part of the guitar I use, as they can easily be added and removed.
Why is it black?
Thing is, the choice of woods for the top of a guitar is basically spruce, cedar or a couple of others, all of which are very plain and boring, so every guitar looks the same. Whereas the back and sides, you can make out of a wood which is beautiful and characterful.
So I'm really into coloured tops and natural back/sides. I think it provides a stunning contrast, and I hope it gets more popular.
