The Filter Twin® uses two identical filters sweeping in opposite directions - one up in frequency, one down in frequency - to give classic 70's-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.
The HT-REVERB can take you from your room to an arena via hall, plate, spring, gate and reverse reverb effects. Valve compression and harmonics are added using the Dwell control, and you can switch the reverb time from short to long while you are playing.
The BOSS OC-3 Super Octave gives guitarists high-quality octave effects with a single stomp. Three modes are provided, including a new Polyphonic Octave mode, a Drive mode with distortion, and the original OC-2 mode. The versatile OC-3 also has separate inputs for both guitar and bass.
