MOD
Influences the gain structure of the AMP selected.
CLEAN: Stock tube amp set-up.
HI GAIN: Gives you an extra gain stage, as if you were to install an
additional 12AX7 tube in the pre-amp section.
HOT: Produces a “spitty, tube-driven-past-the-brink texture.”*

SPEAKER
FLAT: Yields the transparent, natural characteristic of the built-in Tech 21
special design 8” speaker.
UK: Achieves the sound of a “green back” Celestion®-style speaker associated
with early Marshall®4x12 closed-back cabinets. There is greater high mid-range
content and increased low end. It is recommended for big, mega crunch,
balls-to-the-wall results.
US: Achieves the sound of an Electro-Voice®-style speaker used in early
Mesa/Boogie®amps. Similar to UK, but it gives a little more extended range.
It produces a smoother sound with more low-end punch and less upper mid-
range content.
DRIVE
Adjusts the overall amount of gain and overdrive.

MASTER SECTION

EQ
Specifically voiced for guitar, these
active
controls set the tonal balance of the amp
relative to your environment.
LOW, MID and HIGH
Boost or cut ±12dB from the center point (12 o’clock). We recommend starting
with the EQ controls flat, at 12 o’clock. Then try a slight Low boost (2 o’clock)
with a slight Mid cut (10 o’clock), and a slight High boost (2 o’clock).
5
REVERB
Rich, full sounding Accutronics®3-spring reverb. Increase from minimum (7 o’clock).
We recommend starting at 12 o’clock and then adjusting to taste.
LEVEL
Adjusts the overall volume. It also affects the XLR Direct Out, allowing you to block
the signal to the audience or recording console when you want to tune or unplug
your guitar.

REAR PANEL

FUSE
Replace with similar type and same value: 1A/110-120V; 0.5A/220-240V.
IMPORTANT REMINDER: Disconnect power cord before changing fuse.
HEADPHONE
The Headphone output overrides the speaker for undisturbed (and non-disturbing)
practicing. It can also be used as a 1/4" direct out, should an XLR input not be avail-
able on your recorder. You can then use your headphones through the mixer. Be
aware, however, to provide better audibility through headphones, there is slightly
more high end with this output than the XLR Direct Out. Therefore, you should com-
pensate accordingly (or you can opt to use the Effect Loop Send instead).
SPEAKER
By incorporating Tech 21’s exclusive technology with our special design 8” speaker,
the Trademark 10 gives you a choice of speaker styles associated with each of the
most desirable cabinet styles.
If you want to use an external speaker cabinet, simply plug in the speaker cable from
the external cabinet. This will defeat the internal speaker. The Trademark 10 is capa-
ble of driving a 2x12 cabinet or 4x12 cabinet*, but we do not recommend using
speakers rated at less than 8 Ohms, as 4-Ohm speakers could cause undesirable dis-
tortion and potentially overheat the amp. Using 16-Ohm speakers may result in loss
