• The product names mentioned in this document are trademarks or registered trademarks of their respective owners, and are not related to Roland Corporation. In this manual, these names are used because it is the most practical way of describing the sounds that are simulated using COSM technology.

OCTAVE BASS

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

• This function does not work properly when playing chords.
  Mute the other strings and play a single note.

SUPER FLAT

An original amp featuring a wide-range frequency response.
This amp type provides faithful reproduction of the connected bass's own sound. This is a great type for all kinds of connected instruments.
It is ideal for reproduction of an electric upright bass.

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.

B MAN

Models the Fender Bassman 100 ( 4 × 12^n ). This amp has been a favorite since the inception of electric basses.

It features the sonic characteristics of tube amps, whereby increasing the distortion yields a slightly fatter sound.

BASS 360

Models the acoustic 360 (1 x 18"). This amp was used in the '70s not only by famous jazz bassists, but by funk and hard rock players as well. It is characterized by a warm low end, and a contoured midrange.

SESSION

Models the SWR SM-400 + Goliath (4 × 10^) + Big Ben (1 × 18^) . This tweeter-equipped amp is representative of the "L.A. Sound" that emerged in the '80s. It features a wide-range tone that balances presence in the low end with a clear, open sound.

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.

MIC

Select this when a microphone is connected.

• Please note the following points when using a microphone.

• Feedback could be produced depending on the location of microphones relative to the unit. This can be remedied by:

• Changing the orientation of the microphone(s).

• Relocating microphone(s) at a greater distance from the unit.

• Lowering volume levels.

• The sound will be distorted if you turn the GAIN knob up too high. Set the GAIN knob to as high a value as possible before the sound distorts to get the best signal-to-noise ratio.

• Graduations for CHORUS, FLANGER and T-WAH on the panel are for reference. Be sure to check the sound as you adjust the effects.

CHORUS (spacially synthesized chorus)

This is a spacially synthesized chorus.

With spacially synthesized chorus, a method available only in stereo, the chorus effect is created by taking the sound from the right speaker (from which the effect sound is output), and the sound

from the left speaker (which outputs the direct sound), and then mixing them in the actual space. This creates a greater lateral spread than that produced when the sounds are mixed electronically, providing a more natural sense of breadth.

• The chorus effects are designed so they exhibit the greatest effectiveness when you use the unit's built-in speakers. Effectiveness may differ when REC OUT/PHONE are used instead of the built-in speakers.

FLANGER

This creates a flanging effect that creates a sort of spinning sensation with the sound. This effect is characterized by a cool, metallic spinning sensation.

T-WAH

Each genre contains three types of rhythm variations. Pressing the VARIATION button cycles you through the available variations; the VARIATION indicator will be unlit, will light green, or will light red to indicate the change in variation.

5. Adjust the variation to the tempo that you want to play to.

Press the TAP TEMPO button two or more times at the desired tempo to get the RHYTHM GUIDE to play at that tempo.

Sample Settings

ALL ROUND (SUPER FLAT)

An amp sound featuring a wide-range frequency response.

This amp type enables clear reproduction of your instrument's sound.

This also makes it perfect when connecting bass modeling processors or using sound modules like bass synth.

If you are using an electric upright bass, you should try lowering TREBLE.

FINGER & FRETLESS

A bass sound that was popular in the seventies.

This is suited for a Jazz Bass with a rear pickup used. You can get a distinctive fat sound when the bass is fingered near the rear pickup.

In addition, using this setting while playing harmonics in combination with a chorus and a delay enables sounds featuring exquisite reverberation.

SLAP BASS

This setting is suitable for a great slap bass sound. You can get a sticky sound by switching on the COMPRESSOR (COMP). If you apply some reverb, you can create a more sumptuous sound.

To obtain the attacking sound used in rock music, raise the BASS

and TREBLE settings to produce a sound with greater power.

You can add to this effect by reducing the MIDDLE setting.

FUNK WAH (SUPER FLAT/SESSION)

This setting employs the T-WAH feature for a funky sound that responds to the bass touch. The WAH effect becomes even more prominent with the SUPER FLAT or SESSION amp types, which feature response up to the high-frequency range. Use the T-WAH knob to adjust the sensitivity. Adjust the WAH effect with the knob settings according to the output of the connected bass. You can get a different sound for each different playing style, such as slap, muted or glissando.

You can get a light WAH sound by switching the COMPRESSOR (COMP) on in the slap playing style.

OCTAVE IMAGE (OCTAVE BASS)

This is a thicker bass sound created by mixing input sounds with sounds one octave below them.

This is effective in solo performances that use high positions.

You can create some impressive sounds by applying effects like

T-WAH or combining them with DELAY.

MEMO

Adjust the VOLUME knob to an appropriate volume level.
