Getting Started; Instant Gratification; Helpful Hints - Mesa/Boogie California Tweed 6V6 2:TWENTY Owner's Manual

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 sound. 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!
