Now with Double Reaction Bridge!
This guitar is assembled in our new 10,000sq ft manufacturing facility in Sicamous, BC, Canada.
The P555-CE-A is a Grand Auditorium shape guitar with a solid Sitka Spruce top. This guitar has a cutaway design with a Fishman Flex 2-button pickup.
The Fishman pickup system on this guitar will easily be at home on any stage and will faithfully reproduce the full guitar sound. It is braced for an excellent balance between powerful bottom end and a balanced warm top end.
The infinity Indian Rosewood arm rest bevel looks as amazing as it feels.
The "River" side port keeps the guitar sounding natural with crisp highs and warm lows. Back and sides are Mahogany with Mahogany binding.
With sourcing, assembly and critical building steps all done in our factory in Sicamous, British Columbia, Canada, this guitar is built with parts from Canada, China, Korea and the US and is a performer in a classic styling.
The Patented Riversong Adjustable Neck-thru System
Our patented Adjustable Neck-thru System offers many benefits including:
- strength
- intonation
- less bracing
- easier playing (due to the ability to make precise adjustments)
- variable top loading
- an even balanced sustain, tone & volume up and down the neck (yes even on the body),
- no more need for an expensive neck reset
- slinky easy string tension
- reduced heel
- integrated strap pins as part of the structure of the guitar

Riversong's unique patented Adjustable Neck-thru System also has a truss rod that runs the full length of the neck. Most traditional guitars have a truss rod that ends at the 14th fret with an elongated screw head. Riversong necks have a full-length truss rod that adjusts the entire length. This is closer to how an electric guitar is constructed.
The patented Adjustable Neck-thru System has a small amount of flex (like a strat) and this allows regular gauge strings to feel a lot less stiff further enforcing our electric-like feel.
Our Active Body System
Riversong’s innovation is the active body system. It works by moving the neck all the way through the body allowing two things happen:
- The structure shifts from neck joint to the end block
- The mass of the neck is now equal in and out of the guitar and it is free to vibrate like a tuning fork helping to ring up and down the neck and throughout the body. With the structure coming from the back of the guitar, the body and the neck has a little bit of flex (think more like a Strat vs a Les Paul). This flex gives the body the ability to freely vibrate and give the strings a really slinky feel (low tension)

Double Reaction Bridge™
Riversong’s patented Double Reaction Bridge™ (co-developed with Philip Shaheen) is a composite bridge design that fits through the top of the guitar rather than being glued in place. This results in a bridge that’s stronger than traditional wood, will never lift, and makes even contact at the top and bridge plate underneath. Players can perfectly line the strings up with the fretboard and acoustic output is increased by 10%.
This also eliminates the need for pins - with the bridge itself being strong enough to hold the strings in place and the dual-contact design ensuring that the bridge will never lift. Combine this with our Adjustable Neck-thru and Active Body System and you have an incredibly solid guitar that can always be adjusted to fit your personal needs!
