Rivera Sedona 55 Watt Tube Amp Guitar Head.

Such a cool (and tough to find in a head) amp; does Paul Rivera ever have a bad idea? Not that I have seen.

This thing is ultra versatile, as is every Rivera. Killer electric tones along with awesome acoustic tones in the same amp.

Mint condition.



From Rivera:

The all tube channel switching Acoustic AND Electric guitar ampBring back the wood in your tone with tubes!

Sedona, the world’s first all-tube Electric and Acoustic amp. 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!  Available in a 55watt with EL-34s or 25watt with 6V6’s version.

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.

Channel 2 – for clean electric or big warm acoustic tones

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 12″ Celestion T75 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.

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.”


You can order the Sedona with a the ES option. This converts the Sedona’s input into a balanced input using a super high quality Cinemag ® transformer. This adds 4 DB of volume and tone to your balanced output ES equipped Taylor®. The Sedona is the only amp that offers this!!!! Now you will be able to hear how fat and warm you Taylor® can be. If you run the ES-equipped Taylor® in with a unbalanced amp, you are only hearing 3/4’s of the pickup system including the T5. The Sedona 55 is the only amp that can give your T5 full blown acoustic tones and high gain tones, BALANCED!! (USE 1/4 TRS to 1/4 TRS cable to connect Taylor ES with balanced input on Sedona)
