Alternatively, headphones can be plugged in here via the included adapter. For recording, the

optional line out lead connects between the output socket and a recording input.

Power: This socket provides the power input from the supplied 12V DC adapter, or the optional

Power:

12V battery power lead.

Quick Setup Guide:

• Unpack your amp and remove valves from their cardboard boxes.

• Insert the 12AX7 preamp Valve in the left hand valve socket, located nearest to the input

socket. (To insert a valve, locate the pins in the correct position, and plug in the valve.)

• Place the 12AT7 power valve in the right hand valve socket. (To insert a valve, locate the

pins in the correct position, and plug in the valve.)

• Plug the power pack DC plug into the DC socket at the rear of the Stack.

• Plug the power pack into a mains power outlet.

• Connect the speaker of your choice into the output socket at the rear of the Stack.

• Plug your guitar lead into the input socket at the front of the Stack.

• Rotate the volume control (the left of the two controls) clockwise to turn on the amp.

• Adjust the tone control (the right control) to provide the tone that you prefer.

• Enjoy the sound of your amp!

Additional notes:

• The Stack is designed to drive just about any speaker combination and will happily work

with 4, 8, or 16 ohm speakers.

• It can be used with a separate speaker box of your choice. It can also drive the speaker in

a combo amp by removing the speaker lead that connects the speaker to the amp in the

combo and connecting that lead to the output socket of the Stack.

• You will notice that the volume/gain knob in the Stack acts also as a "compression"

control – the Stack is very touch sensitive and you can adjust the sound from clean to

very overdriven just by digging harder into your guitar.

• The optional battery power lead allows for mobile/ battery operation – it has a standard

12V negative ground cigarette lighter plug attached. The amp is internally protected from

accidental reverse polarity connection.

• Due to the nature of the double insulated 12V power supply, you may notice a small AC

buzz produced by your amp. This normally disappears when your fingers touch the

strings of your guitar. To remove any possibility of hum, the amp may be grounded by

attaching an earthed lead to any part of the chassis of the amp.
