That was my first effects pedal! Had it for a loooong time.
the compressor isn't too good, but not too bad either. Don't exagerrate in its settings (or do and destroy your sound intentionally

)
the defretter is a fun sound.
eq is usable.
dirts were a no-no for me
reverb and delays were usable.
synth is identical to the syb-3
chorus sounded identical to a CE-3b to me
Having an expression pedal allows for some whammy-ing and other fun stuff.
the octaver tracked ok in my memory.
the tuner works very good (=TU-2 soft)
Hmmmm.... getting nostalgic
Got it for about €300, played for quite some years with it and got rid of it for about €100 I think.
