This pedal is the Swiss Army knife of Boss.
Two important things:
1. The general configuration is simple and you will need to equip yourself with a sheet and a pen to remember settings (at the beginning).
2. This pedal is the gral saint of lovers rock (broadly defined).
I can get three types of delay, a detune a "spatio-psychedelic" effects, chorus, three pitch shifter, and a reverse mode 11 can either have a whammy (via roland ev-5 ) is a "distortion."
Let me explain, if you have a distortion and you snap mode 11, you will act directly on your distortion, with the ability to slightly thicken your sound, see the complete change.
I hallucinated when I discovered it, because I think it was not the original purpose sought by engineers Boss.
This pedal also allows you to experiment with the pitch-shifter that come in extreme settings improbable sounds (what I called the spatio-psychedelic ') but which requires turning the knobs.
The detune and chorus works beautifully arpeggio.
The reverse is ideal for a saturation of 70 very solos.
I use pitch-shifters only the octave arpeggios or solo.
Finally, delays (short, medium, long) are very comprehensive and we also allow for experimentation by turning the knobs.
Icing on the cake, adding an expression pedal Roland EV-5 also allows you to simulate a Whammy.
To summarize, this is the only boss pedal that brings much effect in one pedal!
Clarification, it's still a Boss, so fans warm delay or vintage effects, go your way, here it is straight, neutral and efficient!
