Q
1) No Power (FOOTSWITCH LED doesn't light up)
!
Is the power supply plugged in (both ends)?
!
Is the mains power on?
!
Has a mains fuse blown?
!
There is a thermal, self-resetting fuse inside the floorQ. Try
disconnecting the power supply, waiting 5 minutes then trying again.
2) The Input doesn't work
!
Is the guitar connected to the input jack?
!
Is the 'INPUT' control turned up enough?
3) The compressor doesn't work
!
Is the FOOTSWITCH on (LED on)?
!
Is the 'COMPRESS' control turned up enough?
!
Is there enough signal, as set by the 'INPUT' control, to drive the
compressor?
!
Is the 'SLOPE' control turned up enough?
4) Too little or too much compression
!
Turn the 'INPUT' control up or down respectively, to adjust the
signal level to the compressor.
!
Turn the 'SLOPE' control up or down respectively.
5) Too much noise
!
Is the 'INPUT' control too high (eg: the input signal is too small)?
!
Is the noise already present in the input signal? (Try unplugging the
guitar).
!
Is the 'OUTPUT' control too high (eg: when lots of compression is
being used)?
6) Sounds distorted
!
Is the 'INPUT' control too high?
!
When using the compressor, is the 'RELEASE' control set too low?

Troubleshooting
Clean compressor sound with mild
control of dynamics.
Adds long sustain to solo distortion.
Also works with a clean guitar for a big
compressor sound
like a controlled
country pick with no pumping and
breathing.
–
These examples were derived using a Laney LT5 5 watt tube amp and a
Gibson SG. Settings will vary with different guitars and amplifiers, so
experiment to find what works best for you!
Turning up the 'SLOPE' gives clean
compressor sustain.
Try these as some starting points. Remember to adjust the 'INPUT' control to suit your amp and guitar, before switching on the compressor.
In each case adjust the 'OUTPUT' control as required, so that there is no change in volume as you switch the compressor on and off.
Driving the input a bit harder with
very short attack and release times,
gives a crunchy sound, still with
control over volume.
