Rivera excels again! With our development of a new Patent Pending 3 Channel Tri-Tone All-Tube circuit architecture, a player is given a range of incredible sounds. From shimmering and rich clean tones, to screaming high gain leads; impeccable note definition along with massive bottom end crunch tones can be reached. Three preamp Channels, powered with 5 12AX7s, work to establish each with distinctive voicing and levels. 3 Spring-Accutronics Reverb containing dual reverb controls, allows adjustment of different reverb levels for lead and rhythm. Footswitchable Boosts on several channels are featured, as well as an Effects Loop Bypass switch.

Lead/Crunch Channels include 3 bands of interactive passive tone controls. A Pull Scoop switch exists to deepen the midrange notch. For the Rhythm and Blues channel, 3 bands of equalization along with a Pull Bright Switch, and a Midrange Pull Notch switch, give a choice of British/Tweed or American Blackface tones. Also, Channel one features a pull contour for fatter bass.

Focus and Presence controls for the final equalization of the EL-34 (55 Watt has 2 EL-34s, and the 100 Watt has 4 EL-34s) power amp section round out the variables. 6L6GCs may be installed by just adjusting the bias (an internal adjustment). Power and Standby switches are on the front panel as well. All channels, boosts, FX loop and reverbs are midi switchable and programmable with the included Rivera Headmaster Midi pedal (FS-9).
Rear panel features include: Series/Parallel Effects Loop with Level and Blend controls, equalized Recording Output, subwoofer Output (for hooking up to our powered Los LobottomĀ® Sub 1 or Sub 2 subwoofers), an Impedance Selector with two speaker jacks, High/Low Power Switch, and a Vintage/Triode switch (allows for 100/50/25/12 Watt Output Power selection) and Midi In/Out/Thru and midi channel selector.
