USER GUIDE

THE JIM KELLEY AMPLIFIER
The Jim Kelley Single-Channel Model is a 60 watt all-tube amplifier designed to retain your guitar’s natural tonal
characteristics. It delivers a broad range of punchy, high powered clean and smooth dynamic overdrive tones. The
Single-Channel model features a versatile pre-amp/power amp circuit, active shelving tone controls, four 6V6 output
tubes and reverb.

Power Selector Switch:
The power select switch offers the following three-positions:
30 Watts: Amplifier operates at half power. NOTE: Middle two 6V6 tubes are active.
OFF: Power is switched off
60 Watts: Amplifier operates at full power
NOTE: In 30-watt position, only the middle two 6V6 output tubes are being used.

Gain:
Operates as an overdrive and a volume control. Responsible for
adding harmonic sustain, richness and depth at higher Gain
settings.
Presence:
(Pull Gain)
Located on the Gain control, this adds high frequencies by
alternating the power section’s negative feedback.
Treble:
Adjusts the boost and cut of treble frequencies. When control is
set to “5”, treble response is considered flat.
Bright:
(Pull Treble)
Located on the Treble control, this provides an additional boost of
treble for a glassy edge to your sound.
Bass:
Adjusts the boost and cut of bass frequencies. When control is set
to “5”, treble response is considered flat.
Mid-Boost:
(Pull Bass)
Located on the Bass control, this adds thickness and sustain for
“fattening up” lead tones.
Reverb:
Adjusts the amount of reverb effect that is added to the
original signal. Turning the knob fully clockwise will provide
the maximum reverb effect.
TONE CONTROLS
HI:
Use this input for guitars with passive or high impedance pickups.
LO:
Use this input for guitars with active or low impedance pickups.
INPUTS

Boost:
(Located on Back)
Provides a Post-EQ boost in gain to the output section for more saturation while leaving the pre-amp clean and
punchy.
NOTE: Boost function requires a latching on/off foot switch to activate.
Stand-By:
(Located On the Back)
With the Power switch in the OFF position and the Standby switch in the Standby position, flip the power switch to
ON. Wait sixty seconds, then flip the Standby switch to the ON position*. To power down, switch the power switch
to the OFF position.
*This will extend tube life.
NOTE: To avoid loud popping or damage, ensure the amplifier is in the Standby position.
Tubes:
The Single Channel tube compliment consists of four 6V6 power tubes,
three 12AX7 and one 12AT7 preamp tubes.

Speaker Outputs

utilizes a custom built output transformer and has two
loudspeaker outputs (one 8Ωand one 4Ω) to interface
with a variety of speaker cabinet options.
