hrmm.. nasubukan ko na ung os2.. tapos meron akong sd1. guess what? i settled for the sd-1.. actually main dirt box ko siya ngayon.
as a stand alone effect.. ang ganda ng sd-1.. with the right settings, you can get enough dirt but still hear the notes clearly. crank the drive up to 10, and you've got a ghetto distortion.
as a boost, better to max out the level, drive at 2-3, tone at 8.. (settings ko to anyway) and your tone cuts through the whole mix especially when mixed with a powerful distortion pedal and chorus.
regarding the os2, meh.. i don't like it. but you can get a decent distortion out of it.. yun nga lang i find it muddy.. parang fuzz na lang siya.
