Compressor/eect types
Eect type Indicator color Explanation
1. COMP Blue
Makes the sound sustain without distorting. This also works as a limiter to suppress high volume
input.
2. T.WAH UP Blue Gives a wah eect according to the dynamics of your picking. The frequency of the lter rises.
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.
