between the pre-amp and the power-amp. Connect your external FX gear input to 
the Little Hill SEND jack, and the FX output to the Little Hill RETURN jack. The effect 
loop can be bypassed by the switch between the SEND and RETURN jacks, or by the 
FOOT SWITCH. 

The FX loop has separate levels for send and return levels. Adjust the send level to 
match the connected devices and then adjust the return level for unity gain. 

You can also use the effects loop as booster. Set the SEND level at 5 o’clock (max) 
and the RETURN level at 13 o’clock or more. Now turn the effects loop on and you 
will have an increased volume. This is very useful for soloing. 

Note that you should set the SEND level as high as possible and the RETURN level as 
low as possible to minimize the noise. 

SEND LEVEL 

Output level to external devices. 

SEND 

Output jack to external device. This is the output from the pre-amp.

 

BYPASS 

FX loop bypass switch. This is a true bypass circuit. 

 

RETURN 

Input jack from external device. This is the power-amp input.

 

RETURN LEVEL 

Input level from external devices. 

FOOT SWITCH 

Connect the supplied footswitch to this jack. Set the channel switch at the front to 
CH1 and the FX loop bypass switch to ACTIVE. If you don’t do this, the footswitch 
will not work. 

LOUDSPEAKERS 

There are three speaker outputs available on the rear panel. They are labeled 
according to the intended speaker cabinet impedance. Use a cable between the amp 
and the cabinet made for speaker purposes. 

WARNING, although the Little Hill has three speaker outputs connect only 

one

 

speaker cabinet with the correct impedance, at a time.

 

POWER ON 

Amps main power switch.

 

MAINS INPUT with MAIN FUSE 

Connect the included power cord in accordance with the voltage and frequency ratings 
listed on the rear panel of the amplifier.
