FILTER TWIN® Dual Envelope Filter
The Filter Twin uses two identical filters sweeping in opposite directions, one
up and one down. This unique design creates classic 70’s-inspired funk
sounds and completely new and original filter tones.
The Filter Twin employs an intuitive four-knob layout. The blend control pans
between the filters, allowing the user to mix how much of each filter they hear.
The threshold control determines how sensitive the unit is to different playing
styles, while the velocity controls determine the speed of each filter.
Features:
• Separate velocity controls for the each filter
• Blend control allows for panning between filters
• Gig-saver bypass (signal passes even if your battery dies)
• Power: Nine-volt battery or optional power supply
• Heavy duty steel construction

I. Functions
A. Top Panel:
BLEND: Pans between the up and down filters. The “up” filter control is indicated by an
arrow pointed up. The “down” filter control is indicated by a down arrow.
THRESHOLD: Controls the sensitivity of the unit to different input levels
VELOCITY UP: Controls the speed of the up filter*
VELOCITY DOWN: Controls the speed of the down filter*
ENGAGE: Toggles between engage and bypass. The blue LED indicates that the effect is
engaged.
*The filter velocity also depends on threshold settings and input level. As the threshold is
lowered and your bass’ input level is increased, the filter velocity increases as well – so
tweak away and have fun!
