Eight Trigrams

Reverb/ Delay/ EchoTremolo, Effects Pedal

Reverb/Delay/Echo Tremolo Pedal - the ultimate effects pedal for guitarists who want to create unique and powerful sounds. Inspired by the concept of the "Eight Trigrams" in Chinese philosophy, this pedal features three effects - reverb, delay, echo with tremolo - that can be combined in various ways to create a wide range of sonic possibilities.

The "八卦" Eight Trigrams concept refers to the eight symbols used in Chinese philosophy to represent the fundamental principles of reality. This concept is reflected in the pedal's design, which allows for the creation of complex and layered sounds that reflect the interconnectedness of these principles.

MODE 1 Dual Head echoverb
Control 1 兩儀 - Reverb
Hall Reverb you can add to the repeats
Control 2 四象 - Delay feedback
Dual head delay feedback. From one repeat to self oscillation.
Control 3 八卦 - Delay time
Dual head delay time. Very quick slapback at minimum. Over 800ms at maximum.

MODE 2 Octave Up Filerverb
Control 1 兩儀 - HPF
High pass filter for the reverb trails. Heavily affects the octave beyond 12:00. Most transparent at minimum.
Control 2 四象 - LPF
Low pass filter for the reverb trails. Basically cuts the octave beyond 12:00. Edge of infinity trails at 4:00. WILD self-oscillation at maximum! Most transparent at maximum.
Control 3 八卦 - Pre-delay time
Pre-delay before hearing the reverb trails. Also controls the SIZE of the trails! Huge complex reverb trails at maximum! Classic (no octave) tones at minimum.

MODE 3 Perfect 5th Echotrem
Control 1 兩儀 - Tremolo Rate
Repeats receive a unique soft tremolo. From no tremolo to very quick pulses.
Control 2 四象 - Delay Feedback
Controls the amount of repeats. From one to self-oscillation! Higher delay feedback will reach higher frequency repeats. (HIGHEST is determined by Delay time)
Control 3 八卦 - Delay time
About 50ms all the way RIGTH. Over 800ms all the way LEFT.
Also sets the PITCH of the HIGHEST repeat and the NUMBER of RISING repeats.
To reach the highest repeat = high feedback.
Adds RIGING REPEATS in Perfect 5th intervals (7 semitones)
