เอฟเฟคเบส Jim Dunlop MXR M88 Bass Octave

This popular bass effect adds a deep note one octave below the note you’re playing for a huge, stadium-filling tone. Compare this to any unit on the market and you’ll be pleasantly surprised. The MXR tracks instantly with what you’re playing, and continues to synthesize useful sub tones for lower fundamentals, where other pedals give up.
