See what the experts are saying about our guitars...

The defining factor that separates a Jasper from any other guitar on the market is its patented (yes, it's actually patented), chambered body design, sidewall venting, and adjustable carbon fiber plate device. It's literally like having a dial on your guitar to add sustain, control feedback, and uncover more harmonic overtones that just seem to hold forever!

This changes everything.

(Dorothy Scott & the Peacekeepers)

Model: Olam

My Jasper Olam is the 1st guitar I’ve pulled off a showroom floor and brought straight out to a show! I connected with it immediately! The feel, tone and look is second to none! It's my new #1! "

Chris Hanaway

(Bassist for Paul Hanna, Jay Stulo, Dennis Shepherd, et al.)

Model: Quatre

This instrument is just on another level. ... The sustain was unlike anything I've ever played. ... Oh yeah, didn't go even the slightest bit out of tune over a full gig. That never happens. "

Paul "Ika Arumba" Winter

(Ike Arumba & the Infidels, Solo)

Model: 1841

My model 1841 skillfully juxtaposes a minimalist, yet attractive, electric guitar appearance with acoustic tones... the harmonic adjustability you can’t get from other brands puts it well above the bar! "

Jay Stulo

(Jay Stulo Band)

Model: Quartermaster-ST

This is without question the most amazing guitar I have ever touched. I fell in love with it instantly. This is just an awesome and amazing guitar! ... There’s not a bad sound in this thing! "

Dennis Shepherd

(Steely Dane, Up from the Skies: The Music of Jimi Hendrix, Solo)

Model: Mana-ST

The Mana-ST is a really expressive guitar ... The way (it) sounds acoustically and responds dynamically is impressive; the way the tone and dynamics shine through when electrified totally blows me away. "

Paul Hanna

(Annex, Solo)

Model: Deja VuDoo

It was love at first sight. This guitar is responsive like no other guitar that I have played. You will be hearing so much about these guitars for years to come. "
