Two filters sweeping at the same time give you a more organic, vocal quality.

The Filter Twin uses two identical filters sweeping in opposite directions - one up in frequency, one down in frequency - to give classic '70s-inspired funk sounds or completely new and original filter tones. Two filters sweeping at the same time give you a more organic, vocal quality and allow you to get expressive new sounds that you can't get from other pedals.

The Filter Twin offers unique filter effects via an intuitive four-knob layout. The blend control allows you to adjust the mix between the filters. The threshold control determines how sensitive the unit is to different playing styles. The velocity controls determine the speed of each filter.

  • Separate velocity controls for the 'up' and 'down' filters
  • Blend control adjusts mix between the filters
  • Gig-saver bypass (signal passes even if your battery dies)
  • Power: Nine-volt battery or optional universal power supply
  • Heavy Duty steel construction
  • Inputs: One 1/4" jack
  • Outputs: One 1/4" jack
  • Controls: Engage switch
  • Warranty: Three-year limited

Add a new dimension to your sound with double the control. Order today.

    Comments about Aguilar Filter Twin Dual Envelope Filter Effects Bass Pedal:

    Having owned this pedal for roughly 6 years now, I think I have a pretty good feel for it. Sound quality is as good as you would expect from Aguilar, and it has taken an absolute beating for years now without a single issue. The ability to blend the up and down filters sets this pedal apart from most of the others I have seen. Set your threshold, then start twisting knobs, you will find some very cool sounds in this pedal. I gave it 4 stars instead of 5 only because I feel that the ability to blend the wet and dry signals with an envelope filter makes it more universally useful (like the MXR). This thing sounds great, but it lacks subtlety. If you like to get funky and have your bass really jump out in the mix, go for it.
