The Knucklehead 100 REVERB
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 6-12AX7s, work to establish each with distinctive
voicing and levels.  Long Pan Hammond Spring 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, and a
Pull Bottom works for adding gobs of fatness on the low strings.  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.  6 footswitchable and distinct
tones are easily accessible.  Footswitchable functions are actuated with
soft-touch momentary contact switches (especially quiet for studio
recordings).  Like all Rivera amps, the LED indicators on the front or rear
panels correspond with the LED indicators on the Footswitch.  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.
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 Lobottom® 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).  A 6 function (FS-4) footswitch is included.

Looking for tremendous power in a small cabinet? This is the
one. Measuring 30.5"W x 14"D x 18"H, the KH 212 has a pair
of Celestion Vintage 30s, and the cabinet is wired in mono with
a 16-ohm impedance. The front is slightly slanted to make the
cabinet easier to hear, plus it's built like all Rivera
cabinets--that is to say, overbuilt, so it's strong, dependable
and roadworthy

Sub 1 Los Lobottom 500 watt JBL Subwoofer
Imagine achieving large stack like tone and levels, with massive
bottom end chunk, with amazing sub-sonic fidelity perfection for drop-
tuning, 7-string and baritone guitar players, from a compact combo
amp system.  Never before has this concept been offered to guitar
players.  Adding the SUB 2 to almost any existing guitar amp system is
as easy as plugging in a few guitar cables.
Small enough to take up minimal space, yet large enough to fit
underneath most combo amps, musicians will be able to upgrade their
existing guitar amp systems and achieve substantial increases in tonal
fidelity as well as dynamic range with a minimum of fuss.
500 watt RMS powered subwoofer, 2-12" JBL drivers, built into a
rugged enclosure that is the footprint of most 4x12” stack speaker
enclosures with enough clean power and dynamic range to keep up
with several 100 watt full stacks!  An answer to prayers for bands that
play large indoor or outdoor venues, connecting the Los Lobottom™
SUB 2, like the SUB 1, to vintage amps is quite easy.  Using a standard
guitar cable from the #2 speaker jack of the host amp to the High Level
Input on the rear panel of SUB 1/2, then connect to Mains Power, and
you are done.

Sub 1 Los Lobottom 300 watt JBL Subwoofer
300 watts RMS powered sub-woofer, 1-12" JBL driver, built into a compact
enclosure, similar in size to most Rivera 1-12” extension cabinets.  
Utilizing a extremely efficient power amp circuit with built in electronic
crossovers, the patented Los Lobottom ™ SUB 1 can be added to any
guitar amp system that has either an effects loop, or an external speaker
jack output.  If used with an amplifier that has an effects loop, the SUB 1
built in effects loop facilities allow seamless effects patching, while
providing controls for high-pass filtering for the host guitar amp.  
Additional features include Low Level Input (for connection to effects loop
send jacks of host amp), Low Level Output (for connection to effects loop
return of host amp), Phase switch (for phase matching between host amp
and SUB 1), SUB 1 Level Control, Peak Level Indicator, High Pass Filter
switch, High Level Input (for connection of the SUB 1 to host guitar amp
systems not equipped with effects loops, like vintage amps), and Mains
Power switch
