Foreword
Thank you for purchasing the Ibanez TB25/TB25R guitar amplifier. Read this manual
thoroughly prior to using your amplifier in order to get the most out of the functions
available. Ensure that this manual is also stored in a safe place.
Features
The TB25/TB25R amplifier head provides 25W of output and is mounted with a
powerful 10-inch Ibanez original Power Jam speaker to provide high-quality sound
and easy operation.
The overdrive channel produces smooth and powerful distortion sounds, and the
clean channel gives you a clean, crunch sound over the full range from lows to
brilliant highs.
The TB25R is also equipped with a built-in spring reverb to bring out the depth in
sound.
Precautions during use
•
Do not subject the amplifier to shocks by dropping, etc., or treat it roughly in any way.
•
Place the amplifier carefully in a stable position. The sound from the amplifier will
vary depending on how and where it is set up.
•
Do not use or store the amplifier in locations where it is subject to direct sunlight or in
environments that experience extreme temperatures and humidity levels.
•
Reduce the volume to ‘0’ or switch off the power supply when connecting the guitar
shielded cable and the effects or other cables required for external connection. Note
that the noise generated when plugs are inserted and removed may cause severe
damage to the equipment.
•
To avoid the danger of fire, do not place containers of liquid on the amp.
•
When you are not using it, leave the power turned off. If you will not be using the
TB25/TB25R for an extended period, leave the power cable disconnected.
Names and functions for each part
1. INPUT jack
The input terminal of standard 1/4" jack. Make the connection from the electric guitar
with a guitar shielded cable.
2. OVERDRIVE - GAIN control
This adjusts the gain (level of overdrive distortion.) when using the overdrive
channel. The amount of distortion will be reduced to produce a clear and individual
sound when the control is lowered, and the distortion amount increased to provide
higher levels of sustain when it is raised.
3. OVERDRIVE - VOLUME control
This adjusts the level of amplifier output when using the overdrive channel. If your
adjustments to GAIN or EQUALIZATION have made the volume too loud, use this
control to lower the volume.
4. CHANNEL switch
This switches between the overdrive channel and the clean channel. If you connect
an external foot switch to the FOOT SW jack, this switch will not function.
5.
CLEAN - VOLUME control
This adjusts the level of amplifier output when using the clean channel. A natural
distortion can be produced by increasing the volume.
6.
BASS control
A shelving-type equalizer for the low-range sound area. It is possible to boost or cut
the bandwidth of 100Hz lower by
±
12dB.
7.
MIDDLE control
This is a peaking-type equalizer. It is possible to boost or cut the 800Hz bandwidth
by
±
12dB.
8.
TREBLE control
A shelving-type equalizer for the high-range sound area. It is possible to boost or cut
the bandwidth of 1.8kHz or higher by
±
12dB.
