Oh, did we mention that the power amp also features all the circuits of those 
classic amps? Yes, it does. All you have to do to get closer to the original is follow 
the tube guide in the app, turn off the amp, change the tubes (no need for 
matched pairs tubes or biasing) and enjoy a different side of the DUALKLONZ 
amp.

 
The amp accepts EL84, EL34, 6L6, 5881, 6V6, KT66, KT88 and many more.

We encourage you to experiment. One amp

s preamp with another type of power 

amp circuit and tubes that have never been used in that configuration. You might 
just find the amp you

ve always been looking for, the one that no one has built 

yet.

Imagine a studio session where you show up 
with one amp, a few other tubes and a bucket full 
of ideas. You can take out your phone, which will 
connect with Bluetooth automatically as soon as 
you open the app, and dial in some sounds to 
express your ideas.

For a live show, just set up your amp as a dual 
channel blues amp one night and a metal 
monster for a different gig the next.

You can also use a MIDI controller to switch 
Circuits in between songs (takes about 1-2 
seconds) to have all these sounds available 
during the set.

Of course we didn

t forget about an FX 

Loop.The amp also has a BOOST switch to make 
the Modern Preamp even more flexible.

We added a second speaker output section 
which can be switched remotely. This enables 
you to use one cab for the clean/overdrive 
sounds and another for the heavier sounds and 
always have the perfect speaker for the “amp” 
of your choice.

Channel, Boost and Speaker Out can be switched 
with standard 1/4“ cables so that is will be easy 
to incorporate this amp into a setup that uses a 
looper/switcher with Switch/Trigger Outs (Like 
the JOYO PXL Line)

But you know what? Forget about all of that! 
Just play it and find out for yourself what the 
real thing sounds like. After that, everything 
else is just icing on the cake!
