Thank you for choosing Orange. You are now a member of the ‘Legendary British Guitar Amplifier’ owners club!
Since 1968, when the company was founded, Orange has been a pioneering force in the guitar amplification
industry. Today, with a team of the world’s finest amplifier engineers, Orange continues to push back the
boundaries of conventional tube amplifier design.
Our commitment to craftsmanship and quality control has allowed our amplifiers to stand the test of time, giving
their owners as much pleasure now, as the day they were bought. To maintain this level of excellence, each Orange
amplifier is put through many rigorous test procedures before leaving the factory.
The warmth, tonal quality and rich harmonics generated by a valve amplifier cannot be reproduced by ‘artificial’
means. Many guitarists have reached the same conclusion: neither the transistor nor microchip is a suitable
alternative to valve technology.
This booklet contains valuable technical and safety information Please take the time to read this manual as the
information may enhance the sound and performance of your amplifier.
We are confident that you will be delighted with your new purchase and that it will provide you with many years
of enjoyment.

8. Bass Control The bass control adjusts the bass response of the dirty channel.
9. Gain Control The gain control adjusts the gain of the dirty channel. High levels of gain will heavily overdr ive
the pre-amp and may sometimes be uncontrollable, especially when used at high volume
levels! This will be more apparent when used as a combo!
10. Treble Control The treble control adjusts the treble response of the clean channel.
Note: When all three tone controls are set to zero, there will be no sound from
the clean channel!
11. Middle Control The middle control adjusts midrange response of the clean channel.

1. Send & Return Sockets The effects loop, send and return jack sockets (rear of amplifier) are intended for use with outboard
pedals or rack equipment such as delay, reverb and chorus etc. Effects such as wah wah, fuzz, distortion
etc, would probably be best placed between the guitar and amplifier input! The effects loop is wired in
series with the pre-amp signal and is completely valve driven!
2. Channel Footswitch Socket The footswitch jack socket (rear of amplifier) enables channel switching using any latching footswitch.
Note: The footswitch will override the channel, clean/dirty switch.
3. Reverb Footswitch Socket Attaching an optional footswitch to this socket will allow you to remotely switch the reverb
effect on and off.
4. Speaker Outputs When using a single Orange 16 ohm speaker cabinet, (i.e. PPC412 or PPC212), attach it to the
16 ohm output socket on your amplifier. When using two Orange 16 ohm speaker cabinets attach each
one to a separate 8 ohm output socket on your amplifier.
When using a single 8 ohm cabinet attach it to either one of the two 8 ohm output sockets
on your amplifier.
WARNING: Never use two 8 ohm cabinets at the same time.
When using a Rockerverb 50 combo with a 16 ohm extension speaker, disconnect the internal
speaker from the 16 ohm socket and reconnect to one of the two 8 ohm sockets. Connect the
extension speaker to the other 8 ohm socket.
WARNING: Orange Rockerverb amplifiers should not be used with 4 ohm speakers.
5. Output Valve Selector Although both the Rockerverb 50 and 100 MKII come fitted and biased with
EL34’s, the output valve selection switch (rear of amplifier) allows for the use of other output valve types,
such as 6L6’s, 6550’s and KT88’s. Note: This switch only puts the amplifier bias in the region for the above
listed valve types! Fine bias tuning for the actual set of output valves to be fitted, needs to be performed
by a qualified service technician!
6. Mains Socket & Fuse Holder This is where your mains lead plugs in. Also the mains fuse is located here.
T2Amp 220/230-240 VAC (T5Amp 100/120 VAC) on 50 watt model.
T 3.15Amp 220/230-240 VAC (T6.3Amp 100/120 VAC on 100 watt model.
7. Mains Voltage Switch Switches amp between 220V and 240V or 100V and 120V. This should be set to the mains
electricity voltage used in the country where the amplifier is to be operated.
8. HT Fuse Holder This is where your HT fuse is located.
2 x T500MA on 50 watt model.
1 x T1Amp on 100 watt model.

Using Your Amplifier
KT88 / 6550
IMPORTANT! Before connecting your amplifier to a power source, please check the following:
1. Ensure your speaker cabinet is connec ted to the correc t impedance speaker output socket, (see Rear Panel, item 2), using a
good quality speaker cable. Do not use guitar leads.
2. Ensure that the voltage selector switch is set to the correct mains voltage, (see Rear Panel, item 5).
When powering up your amplifier, switch to the ensure the ‘Standby’ position is set from the front panel and then switch the power on from the rear
panel, two minutes before switching from 'Standby' to the ‘On’ position. (This will maximise the life of your valves)..
If you are unsure about any of the above points please consult your local Orange supplier.
When powering on the amplifier make sure that the ON/STBY/OFF output switch is in the Standby (middle) position for at least one minute before
switching the power switch to the ON position. (This will maximise the life of your valves).
If you are unsure about any of the above points please consult your local Orange supplier.

WARNING
VALVES AND FUSES CAN FAIL AT ANY TIME!
From time to time output and preamp valves may fail. We suggest that output
valves are changed at least once a year and that all class AB models (50 watts and
above) will benefit from having the bias checked and adjusted. Bias checking must
be carried out by a qualified engineer.
Orange amps are protected from damage caused by valve failure and inconsistent
mains voltage by various fuses.
We recommend that Orange users have a set of spare valves and fuses.
