Designed with Nashville fingerpicking legend Doyle Dykes to handle the nuances of acoustic guitar. 5 - 12AX7 preamp tubes shape 2 full discrete channels of warm tone, while 2 EL-34 power tubes push out 55W to the 12" JBL woofer and single high-power dome tweeter. Channel 1 is designed to produce optimum electric tones, clean or distorted. Channel 2 is tailored for electric or acoustic instruments. Each channel has its own independent 3-band EQ, and the tweeter can be switched on or off to reproduce an acoustic instrument's sparkling harmonics on demand. The anti-feedback equalizer tunes out unwanted noise. Reverb has never sounded sweeter, thanks to the long-pan, 6-spring Accutronics reverb.

The rear-panel tube direct box output includes a level control and pull switch for ground lift. It sends only the instrument's signal through an all-tube, low-impedance, balanced XLR output. The active effects loop has level controls for matching any outboard signal processor to optimize tone and minimize noise. Cabinet is built of hardwood plywood and finished in a buckskin brown Tolex, with 3-tone brown grille cloth, nickel corners, and leatherette handle on top. The ES-balanced XLR input option is for use with the Taylor ES system. FS-7 footswitch included.
