ATS SIXTY

ADVANCED TUBE SYSTEM GUITAR COMBO

USER MANUAL

THF CL

The CLEAN channel on the ATS Sixty is constructed using solid state (transistor)
technology. This allows modern, sparkling clean sounds to be produced, like those
featured on many contemporary recordings.The traditional 3-band equalisation
section with passive tone controls also makes it possible to produce valve-like clean
sounds using the “SOFT CLICK” circuitry.

(2) VOLUME:
Volume adjusts the amplification level of the clean channel. Turned to position 8-9

you can achieve the crunchy “Soft Click” Sound. With pickups delivering more
output (humbuckers) this effect appears at lower volume settings

(3) BASS / MID /TREBLE:

The center frequency and bandwidth for each of this three controls has been
carefully selected to enable you to obtain a broad range of classic and modern clean
sounds. Start with a standard setting (all controls in 12‘0 clock position) and change
it as you want (f.e. more TREBLE for more harmonic overtones and sparkling clean
sounds).

(4) CHANNEL SELECT:
Switches the input signal either to the CLEAN or the OVERDRIVE channel. The

OVERDRIVE channel is active when the LED right of the channel select switch is
on.

TIP: Any conventional
footswitch can be used to
change between CLEAN and
TUBE OVERDRIVE
channels on the Sixty by

TURF

connecting it to
FOOTSWITCH socket on
the rear panel.

OVERDRIVE CHANNE

the

The Overdrive channel on the ATS Sixty consists of a genuine valve circuit (ECC

83). Valves produce a considerably better sound when overdriven than transistors.
The contour of the harmonic distortion and the distinctive compression effect are
the reasons why the authentic warm valve sound is sought after. However, valves do
have a couple of drawbacks!
