The signal chain is automatically optimized to match the eect type that’s selected. You can insert the SEND/RETURN after the PREAMP.

COMP/FX1 (compressor/eect 1)

Averages out the volume, giving a sustained sound without distortion. You can also select from a variety of unique eects.

In manual mode or in memory edit mode, you can turn the eect on/o with the number [1]/[COMP] pedal.

Compressor/eect types

3. SLOW GEAR Blue This produces a volume-swell eect (“violin-like”sound).

4. DEFRETTER Blue This simulates a fretless guitar.

5. OCTAVE Blue Adds pitches one and two octaves lower.

6. HUMANIZER Blue Alters the guitar tone to make it sound more like a human voice.

7. FEEDBACKER Blue Generates feedback performance. The eect is applied while you hold down the pedal.

8. AC SIM Blue Alters the sound from an electric guitar to make it sound like an acoustic guitar.

9. SOLO Blue Use this in combination with the OD/DS or PREAMP eect for a sound that’s optimal for playing

solos.

10. TUNE DOWN Blue Gives the eect of tuning your guitar lower.

11. S-BEND Blue Gives a pitch shift up/down eect that’s not possible when using typical guitar vibrato bar

techniques. The eect is applied while you hold down the pedal.

You can use the BOSS TONE STUDIO for ME-90 dedicated app to exchange the 11. S-BEND with the following eects.

Dierent settings can be made for each patch.

Eect type Indicator color Explanation

D-COMP Blue This models an MXR DynaComp.

RING MOD Blue Combines the internal oscillator and the guitar tone to create an atonal, metallic sound.

POLY OCTAVE Blue An octave eect that works with polyphonic input.
