Hi everyone, first of all I'm sorry for my english who's not perfect. I decided to buy pedals and I would know if these pedals are good or I should buy different one for the same effect. - MXR envelope filter - Dunlop Cry baby - MXR octaver - MXR carbon delay - Soundblox 2 reverb And I saw many bassists using a compressor but I don't know what this pedal do. I saw the mxr 90 phase too, what do you think of this pedal ? I have the BP200 now, I will sell it and I would like to have a sound similar but better of the preset Vibro. Thanks for your help, it will be appreciate.
