Mesa/Boogie CALIFORNIA TWEED 6V6 4:Forty

GETTING STARTED
1. After unpacking the amplifier, check to make sure all the tubes are firmly seated in their sockets as some may have loosened a
bit during shipping.
2. Connect the A.C. Cord to a grounded (3 pin) A.C. outlet.
3. If you have purchased a Head Format, connect your speaker enclosure to the proper matching impedance SPEAKER OUTPUT on
the Rear Panel, most typically to the 8 Ohm SPEAKER OUTPUT jack. An 8 Ohm load is preferable for your first experience with an
amp this dynamic and explosive as you will hear the full power potential and best tonal balance. Combo amplifiers use an 8 Ohm
internal speaker and it should already be connected to the proper impedance SPEAKER OUTPUT. If not, move the speaker cable
to the 8 Ohm SPEAKER OUTPUT jack.
4. Flip the POWER Switch to the ON (Right) position while leaving the STANDBY Switch in the STANDBY (Left) position for at least
30 seconds. This allows the filaments to warm up in the tubes before being put to use. Following this cold-start procedure every
time you power up will increase the toneful life of your tubes.
5. If you intend to connect processing devices to the EFFECTS LOOP, do so now. Look up EFFECTS LOOP in this manual for proper
connection and operation. We recommend auditioning the California Tweed without processing for the first time, just to hear the
pure sounds and get to know the amp by itself before adding processing. This also helps tell you if your processing might be
robbing anything sonically from your new amplifier. If the Loop is to be used, check the INPUT levels on your processor to make
sure they are in the medium to lower range so you can increase the level slowly once you have lifted STANDBY on the California
Tweed and play to view the SEND level coming from the amp.
NOTE: Pedal type Processors don’t usually have an Input Level indicator, some have clip lights, and on either of these types
you’ll need to trust your ears regarding levels
6. Follow the Sample Settings examples below and set the Controls at these approximate settings for a tour through your new world
of TONE. Remember these are just a glimpse at the vast possibilities and are meant to give you a taste of one possible way to set
up your Channels. Feel free to fine tune the sound as you go...you can’t hurt a thing and you will be learning by feel...the best way.
7. Flip the STANDBY to the ON position and enjoy the ride!
INSTANT GRATIFICATION
In case you haven’t yet played your new amplifier, below is just one example of the many ways
to set up a sound. This example demonstrates a Clean sound in the 20 watt power level.
