JB NANO

 

Congratulations on your new JB Nano!

 You now have the unique sound of the 

award-winning JangleBox compressor, but in a much smaller footprint. This 

pocket rocket has all the power of the JB with  even greater performance flexibility. 

The bold sustain will give your Ric, Tele, Gretsch, Strat — whatever the guitar — 

remarkable presence. Unlike pedals that clip or distort the original signal, the JB 

Nano expands the compression “sweet spot” to maintain a clean, even tone, with 

true bypass.

Ideal for a second, smaller pedal board, or to free up some real estate on your 

current board. Don’t use a pedal board? The JB Nano is small enough to just pop 

in your guitar case. 

Compact, powerful and performance ready, the JB Nano is ruggedly constructed 

for demanding pros and aspiring artists alike. Whether you’re looking to get that 

Beatles/Byrds chime, never-ending slide sustain, Nashville “squish,” or just a big, 

clean boost, the JB Nano delivers the distinctive compression edge.

As every guitar-and-amp combination is 
different for each guitarist, you’ll want to 
experiment with the JB Nano settings to get 
the sound you prefer. We suggest starting 
with the 

Gain

 and 

Attack

 knobs turned 

“12:00 o’clock” position, then adjusting the 
compression to your satisfaction from there.

 

O

The 

Gain

 setting adjusts volume and amount 

of compression. The 

Attack

 setting adjusts the 

level (intensity) of compression.

The right footswitch is a  pre-set

 

treble boost.

The JB Nano is designed to expand the 
compression “sweet spot” and not produce 

any distortion or oscillation. Depending on 
your amp  settings, you should be able to set 
the 

Gain

 and 

Attack

 to full  volume without 

creating any “buzz” with your guitar.

 

O

When daisy-chaining a series of additional 
pedal effects with the JB Nano, we recommend 
you start by placing it first in the sequence 
(your guitar should plug into the Nano) in 
order to take full advantage of its true bypass.

 

O

 If you use a 9V battery to power the JB Nano, 
compression will decrease as the battery wears 
out. Remove the four screws on the underside 
of the box to replace the battery.

The JB Nano is easy to set up

Start by positioning both Gain and 
Attack knobs at “12:00 o’clock” 
and adjust from there
