Friedman JJ Junior Jerry Cantrell Guitar Amplifier Head (20 Watts)

The JJ Junior serves up Jerry Cantrell's dirtiest tones in a quieter 20-watt package. A pair of EL84 power tubes offers super dynamic feel and crispy sound.

Dave Friedman teamed up with Jerry Cantrell and captured the Alice In Chains guitarist's iconic tone and ferocity in the Friedman JJ-100 - Cantrell's first ever signature amp. The JJ-100 was an instant success. Not being the types to leave a great thing alone, they decided to cram all that punishing tone and grind into a stage-friendly 20-watt monster. Introducing, the Friedman JJ-Junior.

Watch as Justin puts the JJ Junior though its paces in our exclusive livestream:

The JJ Junior still gives you the same 2-channel, EL-powered tone that has carved out a legendary place in rock. All of the saturated, complex harmonic overtones are still lurking inside, as well as the AC30-like cleans. At 20 watts, the JJ-Junior lets you take the stage, studio, or jam session with total confidence.

Jerry and Dave spent years perfecting the "JJ" sound. Now, you can have the same tonal experience, in a smaller format, without sacrificing the attention to detail that goes into every Friedman amplifier.

The JJ Junior features an internal load and cab-simulated XLR output. Comparing this analog circuit to some of the most intricate computer-based IRs, Dave achieved a direct output you can proudly send to front of house or use in the studio. The JJ Junior also allows you to play "silently," meaning you can safely play the amp WITHOUT having a speaker cabinet connected. The XLR output includes a ground-lift, level, and center/edge of speaker cone simulation switches.

The JJ Junior was specifically read more designed to take pedals well especially boosts, ODs, phasers, flangers, tremolos, and wahs. The ultra-transparent buffered, series effects loop takes time-based effects pedals and rack units equally well. This is the exact same FX loop Friedman uses on all its amplifiers including the legendary BE-100. The head cabinet features beautiful black Tolex, with Baltic Birch construction and the same grille cloth used on the original JJ-100.

I can't believe the amount of vicious, righteous, and jaw-dropping tone this little amp puts out! The JBE setting has an amazing saturated, yet clear sound I've not been able to get out of other amps. Build quality is superb; top-notch!!! This 20 watt amp pushes through 4x12 cabs excellently. Best amp for gigs that don't require 100 watt stacks. LIght and portable, this amp will blow you away. The effects loop is super clear and the xlr line out with cab emulation is the best that's out there. GET THIS AMP!!!
