The Rivera Sedona 55 is an all tube channel switching Acoustic AND Electric guitar amp! Bring back the wood in your tone with tubes! Designed in collaboration with Nashville fingerpicking legend, Doyle Dykes. Now you can switch from luscious all tube high-gain shred, to blues, to country clean and rich bold acoustic tones with one amp!

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.

Anti-Feedback controls to eliminate droning - 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.

Effects loop & Balanced XLR direct out using a Cinemag Transformer - An internal acoustically tuned high-fidelity speaker system consisting of a 12 Inch Celestion speaker reproduces full frequencies and gives great guitar tone for big clean acoustic or high gain electric tones. 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.

The Ninja Boost - Activated by pulling out the Master knob, is a sweet-sounding boost characterized by a more subtle effect onthe harmonics than Channel 1's Boost control while adding sustain. The Ninja Boost helps to drive the poweramp, and the best description of its influence over the tone is that it thickens it.
