FRIEDMAN JEL-20 2-Channel 20 Watt Guitar Amp Head
INTRODUCTION
Jake E. Lee ranks high on the shortlist of influential gunslinger guitarists that emerged as the heroes of a new generation in the early `80s. Best known for the burning guitar work and innovative songwriting, Lee contributed to two of Ozzy Osbourne’s most revered albums, 1983’s Bark at the Moon and 1986’s Ultimate Sin.
With Ozzy, his post-Ozzy band, Badlands and most recently, with his own group,
Red Dragon Cartel, Lee’s playing embraced the athleticism of the 80s while remaining firmly rooted in the hard rock fundamentals of the70s. Jake’s
tonal choices provide the evolutionary glue between the sonics of those two
great eras.
Following the massively successful release of the limited edition JEL-100 signature head, Jake E Lee and Dave Friedman have again combined their legendary ears and talents to create the new JEL-20, a signature amplifier that offers Lee’s ultimate tones in a compact 20-watt package. The JEL-20 is a two channel, EL-84 powered alltube fire breather. In Lee’s own words, “this amp puts the two specific tones I use to create my sound in one head:
The sweetness and warmth of a classic Plexi and the more aggressive slant of
the master volume amps of the 80s — all tweaked to my taste. Dave has an innate understanding of where I’m coming from as a player and we’re alike in the way we hear tones. Dave doesn’t hear things as a technician, he hears things like a musician, and that made him really easy to work with. I grew up in the70s and those muscular, articulate rock tones were the tones I always
sought, but I made a name for myself in the 80s when you needed a little more aggression and a little more scream. I’ve always tried to retain a little of that70s heart and I still do, and that’s what this amp does – though it’s
got plenty more on tap if you need it!”
The JEL-20 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 JEL-20 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 JEL-20 was specifically 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 red tolex, white piping and solid Baltic Birch construction.

the use and maintenance of the amplifier. Take special care to heed all
warning symbols and signs inside this manual and those printed on the
amplifier itself.
POWER SWITCH: Turn this ON to power up your new JEL-20.
SAT SWITCH: Primarily designed to add gain, compression & saturation. It
is normal for the volume level to drop with this switch engaged. Compensate
with the amps’ master volume. (Works on both channels)
CHANNEL SELECTOR SWITCH: Switches between Clean and Dirty channels when
Footswitch is not connected.
BRIGHT SWITCH : 3 position switch that varies the overall brightness of
the Plexi Channel.
MASTER-2 CONTROL: This the JEL Drive channel VOLUME.
MASTER-1 CONTROL: This the JEL Plexi channel VOLUME.
TREBLE CONTROL: This adds or takes away treble. Start at 5 and adjust to
taste.
MIDDLE CONTROL: Adds or takes away midrange. Start at 4 or 5, lower
settings will scoop the mids, higher levels will allow your audience to
actually hear the guitar in the mix.
BASS CONTROL: This adds or takes away bass or bottom end. As the amp gets
louder you may want to back this off a bit. Start at 7-10 for bedroom volumes.
GAIN-2 CONTROL: This adds gain/distortion for the JEL Drive channel.
Adjust to taste. Don’t be afraid.
PULL GAIN SWITCH: A lower gain 800-esque sound to a higher gain boosted
tone on the JEL drive channel.
GAIN-1 CONTROL: This adds gain/distortion for the JEL Plexi channel.
INPUT: Just like it says, this is the Guitar Input Jack.
FOOTSWITCH JACK : This is where you plug in the footswitch.
SEND JACK: This is where you plug the INPUT of your Effect(s). Use a high
quality shielded guitar cable.
RETURN JACK: This is where you plug the OUT of your Effect(s). Use a high
quality shielded guitar cable.
BALANCED OUT: XLR output used to send your JEL-20 tone straight to the
mixing board. For silent recording ability, have no speaker cable plugged in
to the USE FIRST speaker jack.
SPEAKER OUT JACKS (2): Plug speaker cabinets here. Set Impedance selector
to appropriate position.
IMPEDANCE SELECTOR: Select between 16 or 8 Ohm to match your speaker set-
up.
PRESENCE CONTROL: Adjusts the upper mids and highs in the power amp
section. This is global on all channels. Start at about 4-5 and adjust to
taste.
**Note: THIS POT WILL BE SCRATCHY– THIS IS NORMAL
HT FUSE: Only replace with Type indicated on rear panel. If this fuse blows,
it’s most likely a bad power tube.
MAINS INPUT: Plug the supplied IEC power cord here.
MAIN FUSE: This fuse is in the compartment found below the AC receptacle.
Replace only with type indicated on rear panel. This is also most likely the
result of a bad tube. Constant blowing of this fuse (even when using new
tubes) is an indication that something could be seriously wrong with your amp.
STOP and call us so we may help you diagnose.
