control, or even some of the other controls, to see if perhaps a slight adjustment of settings will eliminate or
reduce the feedback, resonance or anomaly.
MULTI-WATT™
As mentioned in the overview of this manual, your California Tweed presents the next evolutionary step in
traditional amp all-tube power sections. This dream-realized flexibility in power ratings all in the same amplifier
is both revolutionary and extremely useful. It features the iconic and gig-able 20-watt power rating and two
lower power options across 2 Operating Classes, Class AB Pentode and AB Triode along with Single Ended
Class A wired Pentode for a total of 3 Wiring Options (listed below).
These lower to lowest wattage levels can enhance many musical styles and cover small to midsize venues.
The best part is you'll have room to move up or down the power scale seamlessly on the fly in the heat of a
performance with the handy front panel Multi-Watt™ rotary control.
With this patented power technology, tuning the headroom and riding the threshold of sweet, musical clip-
ability is as simple as a flick of the wrist. It greatly enhances the usefulness and flexibility of a single channel
traditional style amplifier and allows a much wider range of sounds based on power section performance, and
where appropriate, power tube saturation.
Three power ratings featuring 2 operating classes and 3 wiring options are provided:
•
20 watts running 2 x 6V6s operating in Class AB Pentode
•
10 watts running 2 x 6V6s operating in Class AB Triode
•
1 Watt running 1 x 6V6 operating in Single Ended Class A Pentode
Among these different wattage selections and "voicings" (as each has its own character, clip threshold and EQ
curve) you will find many different tones and responses that allow you to roam much farther than any traditional
amp before. Spend time exploring each of the wattage ratings to learn its character and best application...you'll
quickly understand that whether clean or overdriven, the California Tweed is also California Gold when it comes
to iconic guitar sounds in the 6V6 realm.
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 right) 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 during power up, 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 (switch left). Wait at least 30 seconds and
then flip the STANDBY switch to the ON position (switch right). STANDBY is also very useful as a mute for
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 completely with the POWER switch 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 below when
you power back up, even if the amp is still "warm". The filaments in the tubes cool much more quickly than
