The Tentacle is a classic analog octave up effect. It is the very same octave from the popular Hoof Reaper pedal. It doesnt need any knobs, just one footswitch. The EQD Tentacle works just as well on its own as it does with fuzz, overdrive and distortion pedals. It can be activated in standard latching operation or in momentary operation, by just holding the footswitch down for as long as youd use the effect. The Tentacle is all analog, True Bypass with a silent relay-based switching, equipped with new enclosure and is hand made in Ohio, USA.
