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.”*

*This descriptive quote is taken from Tom Mulhern’s review of the SansAmp Classic pedal, published in Guitar Player Magazine.

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.

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.

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).

DRIVE

Adjusts the overall amount of gain and overdrive.

MASTER SECTION

EQ

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).

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
