Bass Expansion Pack

Whether you play a 4, 5, or 6 string bass, you can add a collection of pounding sound effects to your low end frequencies right with the new BIAS FX bass pack. It features 7 must have bass stompboxes to your arsenal: 1 bass preamp , 1 overdrive , 1 EQ , 1 Compressor, and 3 modulation pedals. Let’s go in-depth each pedal:


  • EQ Bass: a graphical equalizer for bass players to easily shape their tone while retaining the signal’s transparency, a must have item for all bass players.
  • Comp Bass Compressor: an analog based compressor dedicated on the low frequencies, providing a very easy control and warm and smooth sound.
  • Drive Bass DI Drive:  the DI Driver captures the warm and rich tones of the most sought-after tube bass amplifiers. This bass DI is capable of dialing up big vintage tube tones, bright modern slap sounds, solid distortions, and all in between.
  • Mod Bass Chorus: this chorus pedal allows you to add sauce to your tone but still can retain your low frequency by adjusting low filter and blend portion – it’s solo time!
  • Mod Bass Octave: this pedal emulates the analog octave divider to create a single note one octave below the pitch of the played note, adding a new dimension to your sound. Designed to improve and enhance the tone of fast bass chops.
  • Mod Bass Envelope Filter:  it’s funky time – this pedal increases the frequency response and improves signal-to-noise ratio making it the perfect for use with both guitar and bass.
  • Drive Bass Deluxe Drive: this pedal gives you a classic bass drive tone for modern bass players, providing more tone shaping options than ever before.
