Trippy ring modulation meets tap tempo.
The Ringtone TT from ZVex is a tap-tempo sequenced ring modulator pedal for guitar. The Ringtone TT's controls are as follows: from the upper left, a sequence/random/step switch which sets the function of the left stomp switch, a speed control for the sequence/random mode, 8 individual carrier pitch adjustment knobs, the left stomp switch for entering tap tempos or operating as a manual step control, and the true-bypass stomp switch on the right. Also, inside the distortion pedal there is a trim-pot adjustment on the small daughter board attached to the bypass switch for setting the mix of ring-modulated sound versus direct guitar. The ZVex Ringtone TT is powered by a 9V battery.
Note: Due to the nature of each hand-painted Ringtone TT pedal, there may be a slight difference in design from the posted image.
