The Dean 12 Gauge Solid Top Acoustic-Electric Guitar w/Aphex has some unique features and special electronics that are designed to produce improved acoustic sound on stage. The Dean 12 Gauge lives up to its name with a mahogany gun stock pickguard and a shotgun shell knob inlay at the 12th fret. Acoustically, this guitar produces a loud and well-balanced sound thanks to its solid spruce top and mahogany body. Other refinements include a comfortable mahogany C shape neck, maple dot inlays, nickel hardware, and APHEX electronics. Aurel Exciter Optimized for Dean's acoustic/electric guitars, the Aurel Exciter adds air, bite, definition, percussive attack, and better clarity by enhancing the natural harmonics of the sound. No other exciter has the musicality of the true Aurel Exciter found in Dena acoustic/electric guitars. Big Bottom The Aphex Big Bottom circuit dynamically enhances the low end by deepening and expanding the bass tones according to an adaptive process. It's not just an equalizer boost - it increases volume before feedback. The effect fattens the tone while it extends the guitar's bass producing capability. The Aphex brings out the box and adds a warmer tone that makes your guitar sound bigger and fuller. Simply press the Aphex button and the guitar comes alive.
