CONGRATULATIONS!

You have just purchased the legendary and mysterious ‘333’ tone that many refer

Soldano, in SEATTLE, WASHINGTON, and meticulously assembled to assure that
it meets the highest quality standards and value.

Whatever your musical taste may be, you will enjoy the versatility, portability,
and long-term durability of this kick ass, tube driven, rock tone factory.

Wait, huh, what? You didn’t buy a Jet City extension cabinet yet? Huh? No stack?
What will your new ‘333’ combo sit on?

Please go back and buy one; you deserve the whole enchilada, my friend. You’ve
come this far, so we know you can do it. Our cabinets are loaded up with
Eminence Legend speakers, which as we all know, are the preferred speakers of
our beloved designer.

Thank you for purchasing a JET CITY AMPLIFICATION product.

BEFORE YOU ROCK

Before operating your JCA5012C please make sure of the following:

● First, make sure the JCA5012C is properly connected to a speaker load

(either the internal speaker, an external speaker or both).

● Plug the power cable into the back panel and plug the cable into a power

receptacle. Turn on the power switch on the amplifier and wait about 30
seconds for the tubes to warm up.

● Turn on the standby switch.

● Turn up the volume knob on your guitar and impress your friends with your

amazing new tone.

WARNING: If a speaker or suitable “dummy load” is not plugged into
the speaker jack, output transformer failure will occur. OUCH! This is
not good and NOT covered under warranty.

WELCOME TO JET CITY

The Jet City Amplification JCA5012C is a 50 watt, 2-channel guitar amp combo with

independent preamp and master volume controls for each channel.

The tone controls shape the sound of both channels and are interactive which

means that each control will affect the others. This gives you the flexibility to

dial in all the unique and subtle tones you've been searching for.

The Jet City Amplification JCA5012C also has a global presence control that

lets you add high-end sparkle to both channels. Other features include a

tube-buffered serial effects loop, multiple speaker impedance outputs, and a

foot-switch input for switching channels on the fly (foot-switch included).

GENERAL OPERATION

The JCA5012C’s shared EQ controls allow you to dial up the right tone for you
and your guitar no matter what your gain and output levels. The two

independent preamp and master controls give you great stage versatility by
allowing you control over each channel’s gain level AND individual output
levels.

FEATURES

● 2-Channels with independent preamp and master volume controls

CRUNCH and OVERDRIVE

● 50 watts of tube power

● 100-watt, 12” Jet City Custom Eminence speaker

● Tube-buffered serial effects loop

● Parallel 4-ohm, parallel 8-ohm and single 16-ohm speaker outputs

● Included FS-1 foot-switch for channel switching

● CRUNCH Channel Preamp Gain: Adjust the amount of gain (distortion) that

the amplifier produces in the CRUNCH Channel.

● OVERDRIVE Preamp Gain: Adjust the amount of gain (distortion) in the

OVERDRIVE Channel. The higher the preamp setting the more overdriven

the sound will be.

● BASS, MIDDLE and TREBLE: allow you to control the tone.

● CRUNCH Master Volume: will let you adjust how loud the CRUNCH

Channel’s output will be.

● OVERDRIVE Master Volume: will let you adjust how loud the OVERDRIVE

Channel’s output will be, independent of the CRUNCH Master Volume.

● PRESENCE: adds an overall brightness, which can be handy when trying to

cut through in a ‘dead’ room.
