3. SHAPE Switch

This effect alters the COSM amps’ tonal qualities. The particular effect obtained varies according to the amp selected with the Type switch (➃).

4. Type Switch

You can select from the following seven amp types:

OCTAVE BASS

This original amp type creates sounds one octave below the input sounds and layers them together to create a fatter bass sound.

Offers more edge in the octave sound.

*This function may not work properly when inputting chords; for example, sounds may not play, or they may be played at incorrect pitches. Always input a single note.

FLIP TOP

Models the Ampeg B-15 (1 x 15”). This amp provided the underpinning for many of the most famous Motown hits. It features a fat sound, while the amp's compact cabinet produces a distinct contour.

Offers more nuances of your picking expression.

B MAN

Models the Fender Bassman 100 (4 x 10”).

This amp has been a favorite since the inception of electric basses. It features the sonic characteristics of tube amps, whereby increasing the distortion slightly yields a fatter sound.

Offers a tone with boosted midrange “fatness.”

T.E

Models the Trace Elliot AH600SMX + 1048 (4 x 10”) + 1518 (1 x 15”). This amp was used widely by rock bands in the 1980s. Its wide range, clear attack, and other features make it a great amp for all kinds of performance situations.

Offers more attack.

BASS360

Models the acoustic 360 (1 x 18”).

This amp was used in the ’70s not only by jazz bassists, but by funk and hard rock players as well. The tone features a warm low end with a midrange that maintains a clear contour, even with finger picking.

Offers more nuances of your picking expression.

SESSION

Models the SWR SM-400 + Goliath (4 x 10”) + Big Ben (1 x 18”). This tweeter-equipped amp is representative of the “L.A. Sound” of the eighties. It features a wide-range tone that balances presence in the low end with a clear, open sound.

Offers a tight tone with a cut midrange.

CONCERT 810

Models the Ampeg SVT + 810E (8 x 10”).

This amp typifies the rock sound that relied heavily on combinations of high-output tube amp sections and large-sized cabinets.

The characteristic sound is one of overwhelming low-frequency sound pressure.

Offers extra heavy bottom sound.

5. GAIN Knob

This adjusts the preamp section’s input level.

Turning the knob to the right increases the gain.

Using a high gain setting allows you to get an overdrive sound.

Set the knob to as high a value as possible before the sound distorts to get the best signal-to-noise ratio.

6. VOLUME Knob

Adjusts the overall volume.
