JIM KELLEY SINGLE CHANNEL REVERB HEAD

The Jim Kelley Single Channel Head 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 preamp/power amp circuit,

active shelving tone controls, four 6V6 output tubes and reverb.

Gain

Operates as an overdrive and a volume control. !This is

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

altering 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”, bass 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. !!

The power select switch offers the following three-positions:

30 Watts: !Amplifier operates at half power.

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 used.

Standby

(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, simply switch the power switch to

the OFF position.

* This will prolong tube life.

NOTE: To avoid loud popping or damage, ensure the

ampliﬁer is in the Standby position.
