Rivera Sedona 55 Acoustic Guitar Combo Amplifier (55 Watts, 1x12")

Product Description

The Rivera Sedona 55 acoustic guitar combo amp, the world's first all-tube Electric and Acoustic amp designed in collaboration with Nashville finger-picking legend, Doyle Dykes. Accolades have been given to Sedona from all over the world.

Sedona features two independent and different preamplifier channels. Channel 1 is designed to produce optimum electric tones, clean or distorted. Channel 2 is tailored for electric or acoustic instruments. Sedona's specially designed Tweeter can be switched on or off to reproduce an acoustic instrument's sparkling harmonics on demand. In addition, the Tweeter's operation is linked to Channel 2 and is automatically disengaged when Channel 1 is selected.

An easy to use anti-feedback equalizer tunes out unwanted notes that would otherwise drone or squeal with sensitive acoustic Instruments. Switched from the front panel, the anti-feedback filter is also linked to Channel 2, and is automatically disengaged when using Channel 1. Reverb has never sounded sweeter, thanks to a long-pan, 6-spring Accutronics reverb.

Another Rivera exclusive feature, the Sedona's built-in rear-panel tube direct box output, includes a level control and a pull switch for ground lift. It sends only the Instrument's signal through an all-tube low-impedance, balanced-line XLR output invaluable on-stage or in the studio. An active effects loop with level controls allows for matching any outboard signal processor for optimum tone and minimum noise.

An internal acoustically tuned high-fidelity speaker system consisting of a high-efficiency 12 inch JBL speaker (15 inch JBL-100W Model) reproduces full frequencies and gives great guitar tone. A single high-power Dome Tweeter adds sibilance and definition to the high-end strings, especially on nylon or gut string instruments. Separate tweeter and full-range speaker output jacks coupled to an impedance selector allow connection to a Sedona Extension Enclosure to cover larger venues. If you find yourself playing electric 50% of the time, try the Sedona 55 with a Celestion T-75.

Never before has an amp received so many rave reviews from guitar magazines. Guitar World as well as Guitar Player have used Sedona as their benchmark for testing other amps as well as many acoustic guitars. Guitar Shop Magazine said "This is undoubtedly the best acoustic/electric amp ever made.." Musician Magazine awarded Sedona "Amp of the Year."
