MODE SELECT

Each Channel contains a MODE SELECT switch which allows selection of any one of the three preamp

Modes (CLEAN, DRIVE and HI). The Channels are identical (except for any minor tolerance differences in the actual Pots, so you
may dedicate your Channels as you see fit with no compromise or limitations.

POWER

This switch controls the AC power Mains in your amplifier. Always make sure the (supplied) IEC Power Cable is connected

to a grounded Outlet delivering the proper AC voltage – 117V USA. Never alter the Power Cable as doing so may cause damage to
the amplifier, increase the risk of electric shock for you, and will void your Warranty. Always follow the Cold Start Procedure below and
allow the tubes to warm up before turning the STANDBY on (switch up) as this will help the tubes and all other components in your
amplifier to provide years of reliable service.

STANDBY

This large toggle controls the high voltage to the power tubes and from cold start, helps minimize the inrush of current

and reduces the “shock” on them, which ultimately helps increase their useful life. Just like a light bulb, much of the wear on tubes
happens at the instant of power up. Minimizing this shock and allowing them to warm up more slowly ensures they will give you the
longest life possible.

Before Power is switched on, make sure the amp is in STANDBY. Wait at least 30 seconds and then flip the STANDBY switch to the
ON position. STANDBY is also very useful as a MUTE for either short interruptions – like changing instruments or patching cables as
well as longer intervals such as Set Breaks or other extended periods.  While you can leave the amplifier in STANDBY mode for hours
with no harm, it is probably wise to power down if you know you won’t be playing for an hour or two.  Why waste the electricity? Just
remember to follow the Cold Start procedure mentioned above when you power back up, even if the amp is still “warm”.  The filaments
in the tubes cool much more quickly than even the glass they are encased in, and they return to their “cold” state even after a short time
with the power off.  This procedure, when followed religiously, will help prevent tube problems and extend their useful life substantially.

COLD START PROCEDURE:
(Use every time amplifier has been switched off for more than 3 minutes)

1. Switch to STANDBY
2. Turn POWER to ON.
3. Wait AT LEAST 30 Seconds, preferably longer, for tubes to warm up.
4. Flip STANDBY to ON

NOTE: This Cold Start Procedure is an important part of ensuring maximum tube life and reliability. Like a light bulb, the most wear
occurs in the instant (short period, first few seconds) voltage is first applied. Like a light bulb, if a dimmer is used to reduce the volt-
age for the first few seconds or so of use, increased longevity is the result. The STANDBY is the amp’s equivalent to a dimmer and
using it in the above described method will ensure the longest life and best performance from a set of tubes (especially Output tubes).

REAR PANEL

POWER OUTLET/AC MAINS SOCKET: (Removable IEC TYPE)

Underneath Rear Panel: This is the AC MAINS Power

Cord Socket. The standardized removable power cable supplied with your amp can only be plugged in one way. Always connect the
male end to a grounded (3-Hole) wall socket with the proper voltage present (117 Volts on U.S.A. Models). To Avoid The Risk Of
Shock, Never Alter The Power Cable in any way. Altering the Power Cable will void your warranty and put you at risk while leaving
your amplifier open to the possibility of damage.
