The killer KR100 tweaked by Slipknot's guitar overlord.

Mick Thomson and Paul Rivera adjusted the frequencies in the Rivera KR 100's midrange to give the amp more punch and bring more definition to the bottom-end. Mick also had the top end a little sweetened to complement his guitars. Mick wanted this amp head to be flexible for all playing styles but specialize in aggressive, quick and defined riffs.

With their development of Patent Pending 3 Channel Tri-Tone All-Tube circuit architecture, a musician 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. The Mich Thomson amp head has 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 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) and Midi In/Out/Thru and midi channel selector.

Rivera KR7 Head

By ESPMan275

from Australia

I bought the KR7 (one of the first here in Oz) in Nov 08 and I couldn't be happier with it. I use a variety of guitars through it - Strats, Tele, Les Paul, PRS and ESP Horizon and they all sound terrific - this amp lets you hear the real tonal differences of each guitar. This head is extremely versatile and to think its just for metal heads is not doing it justice, you could easily do a jazz or country gig with it. The controls are very sensitive and give you incredible variation - its definitely not a one-sound amp like so many are these days. The clean channel was the biggest surprise - great sustain and goes from black face to tweed to nearly acoustic. Heck, my dad can play even play his pedal steel through it so thats saying something! Ch2 has a great range of rock tones but it has a bit more fizz if you need it which is nice. Plenty of drive and sustain etc. I can easily use this channel alone all night. Ch3 is just nasty, huge gain, harsh voicing - probably more percussive than melodic, but no doubt there'll be people out there who will love it, at least they get the choice. Each channel has a boost function that gives more gain and a touch more volume, not a proper volume boost but at least the effects loop can do that for you. The power options at the back do nice job of changing tones which I guess just adds versatility. Volume is no problem whatsoever - you'll have plenty but its no bedroom buddy thats for sure. This head is built like a tank...and has the weight of one too. I've lifted 212 valve combos that are lighter! But its built beautifully and the componentry is top notch. I tried other 'high-end' amps and actually was intent on buying a similarly priced Mesa. I was so glad the KR7 arrived in the country before I laid out the cash because the tone of the KR7 did it for me. Other big money amps may have more bells and whistles but for me, the tone and versatility of the KR7 sold me in a second. Highly Recommended -go on spend the money, you won't regret it!!

This amp is absoloutly amazing better than a diezel, bogner you name it. Mick is not only a terrifying guitar wizard but a tone guru. This amp has everythig you need, it barks, punches, squels, purrs, bites, sparkles and is as sweet as it gets. Buy it or else you'll never know tone, sincerely metal mark.

Words simply cannot do this amp justice. Riveras are the creme of the crop as far as versatility and durability goes, and the KR100 MT (or as its really called, KR7) is no exception. No matter what your music style is, whether it be clean country, to classic rock, to all out metal, this amp is the only amp you will ever need.
