Gear Hunter

Accessories Included: Channel/FX-Boost footswitch and footswitch cable

This 2010 Krank model Nineteen80 is based on a hot rodded JCM800 2203 model, but with all the features you wished the JCM800 had.

* A great sounding, footswitchable, Fender-ish clean channel
* Then a fire breathing "modded '80's Marshall" distortion channel with enough gain on tap to solo effortlessly.
* AND a footswitchable FX loop that doubles as a solo boost for both channels!
* 80 (conservative) watts of power with two 6550 tubes.
* A wide range of crunchy/heavy tones with the (midrange) SWEEP control.
* Boost your leads and switch your delay/reverbs in/out with the switchable FX loop
* Made in the USA

Here's some extra info from Premier Guitar in 2010:

Krank is known for higher gain heads favored by the likes of Dimebag Darrell. When I found out I would be reviewing the Nineteen80, I asked around to see what kind of buzz the amp had going. “It’s a JCM 800 on steroids,” I heard over and over. Having owned many JCM 800s in my day—some actually “on steroids” via modifications from José Arredono and Lee Jackson—I was ready to take on the latest rendition of the classic.

The Specs
The 80-watt Nineteen80 head features two 6550 power tubes and five 12AX7 preamp tubes. The 6550 power tube was a popular choice among early amp mod gurus, as it’s known for a big low end and a lot of power and reliability.

The front panel features (left to right) Power and Standby switches, a Krank channel with Presence, Sweep, bass, Midrange, Treble, Master, and Gain. Following the Krank channel is the Kleen channel with Volume, Treble, and Bass controls. A channel selection switch is located between the two channels, and Input and Footswitch jacks round out the front panel on the right. The knobs are a white chicken-head type, which, combined with the “salt and pepper” basketweave, makes for a nice vintage look. Black grille cloth is also available.


The back panel is fitted with an effects loop featuring Send Level, Send and Return jacks, FX Boost button and Return Level. To the right of these controls is an ohm selector switch with selections of 4, 8, and 16 ohms, two speaker output jacks, and a voltage selector for 115 or 230 volts, allowing the amp to be easily used in other countries.

The Effects Loop
Guitarists as a whole have a love-hate relationship with effects loops. Many feel they change the sound of the amp by affecting the degree that the power section is pushed when they are not unity gain. Other concerns are that there are different level requirements depending on the effect used. If you are running an old analog delay pedal in a plus four or line level loop, it will distort the front end of the pedal and reduce it to a very undesirable tone. Meanwhile, line level rack effects usually have input and output control settings and work well with these types of loops.
