Front Panel Functions
1. Input Jack- High impedance input to the amplifier. Plug in your instrument here.
2. Bright Switch- This switch provides an extra boost to the high-frequency range.
3. Volume- Adjusts the loudness of the amplifier, from quiet and clean at counter-clockwise, to
loud with a nice phat overdrive at full clockwise setting.
4. Bass Control- Adjusts the bass response. In the full counter-clockwise position, low frequencies
are cut. In the full clockwise position, low frequencies are allowed to pass to the next gain stage. To
retain clarity, turn the Bass down at higher volumes.
5. Treble Control- Adjusts the high frequency response. In the full counter-clockwise position, high
frequencies are bypassed to ground. In the full clockwise position, high frequencies are allowed to
pass to the input gain stage.
6. Reverb Volume- Controls the amount of reverb from none at counter-clockwise to deep and
lush when turned to the full clockwise setting. Please note that the reverb section on the Band-
mate 15 can run independently from the preamp section, and therefore can be used on it's own as
just a reverb unit.
7. Reverb Tone- Adjusts the 'colour' of the reverb, from dark to bright by bypassing specific
frequencies.
8. Indicator Lamp- This lamp will illuminate when the power switch is in the “up” position, indica-
ting the unit is receiving A/C power
9. Stand-by Switch- Should be in the “Off” or “stand-by” position when you apply power to the
unit. After a few seconds, place the switch in the “On” position to use the amplifier. You may leave
the unit “powered up” and place this switch in the “stand-by” position to mute the output.
10. Power Switch- Turns power on.

Rear Panel Functions
1. Remote sw reverb- To turn the Reverb effect on/off remotely, use a standard corded foot switch
with 1/4 Jack, (Latching)
2. Speaker Output Jacks- There are two sets of speaker output jacks, and the nominal impedance
of the Roadie Bandmate 15 is 8-16 ohms. The Bandmate 15 comes standard with a 16 ohm Cele-
stion Vintage 30 speaker, which should be plugged into the single 16 ohm output. The amplifier
can power a pair of 16 ohm speakers and combine them to an 8ohm load, or you can run a single
8 ohm speaker, by plugging into the output jacks marked 1 x 8 ohm or 2 x 16ohm.
3. Fuses- In the unlikely event that a tube fails, the Bandmate 15 is protected by a 1 Amp slowblow
fuse for 115v and 230v, and a Voltage fuse 315mA.
Please consult us or a qualified tech for assistance in the event of a fuse blowing.
4. Power Switch- To select between 115v and 230v A/C power sources.
5. A/C Input- Connects the amplifier to A/C power via the power cord supplied. Unless otherwise
specified, your amplifier is designed to operate on 115-230 volts A/C, 60 cycles.

Biasing your Bandmate 15
The Bandmate 15 is a cathode bias (self bias) amplifier and as such does not require a bias
adjustment when changing tubes. Please use matched pairs of output tubes for maximum
performance. The Bandmate 15 can only use matched pairs of EL84 power tubes.

WARNING! NO USER SERVICEABLE PARTS INSIDE! Refer to qualified service personnel only.
Power cord, for your own safety, connect this amplifier to grounded A/C receptacles only.
