Meris Hedra 3-Voice Rhythmic Pitch Shifter Pedal

3-voice rhythmic pitch shifter pedal capable of adding 3 harmony voices to your instrument - features pitch glide, micro-tuning, 4 individual delay configurations, adjustable pitch correction, and MIDI keyboard control

Product Description

The Meris Hedra is a three-voice rhythmic pitch shifter pedal that lets you sculpt stunning three-dimensional soundscapes using a guitar, synthesizer or MIDI keyboard. Dial in tight, rich harmonies with adjustable pitch controls. Create complex rhythmic patterns with tap tempo delays. With Hedra, you can create sounds you didn’t even know were possible.


Hedra features simple controls and a compact, intuitive interface. Quickly re-voice melodies in real time using selectable pitch correction types. Select any of the 12 standard scale types using the Key control to automatically pitch correct the incoming signal. Or use the chromatic setting for far-out jazz fusion solos!

Three dedicated Pitch controls allow you to set pitch correction for each voice. Quickly and accurately dial in rich harmonies with stepped controls and clear labeling for common intervals like 3rd, 5th 7th and octave. Sweep through intervals smoothly or hard step for dramatic pitch effects. Choose from 18 different intervals, spanning across four octaves for huge harmonies. Or use the Micro Tune controls to create chaotic atonal cacophonies. Blend the pitch-shifted voices with the original signal to create the perfect balance using a dedicated Mix control.


Four delay configurations allow you to create complex rhythms and pitch-shifted sequences. Delay times for each voice can be controlled using familiar tap tempo controls. Advanced feedback routing lets you create cascading delay sounds—or intentionally create musical feedback for those intense noise-rock sessions.

Take your tone even farther with Glide Mode, which lets you slide between pitches at a speed of your choosing. Create dreamy, ethereal textures with the Half Speed and Auto Swell functions.


Hedra isn’t just a guitar pedal—it’s a symphony in a box. Toggle from Line to Synth level inputs and plug in your favorite synthesizer. Or connect your favorite MIDI controller using the TRS expression jack and conduct a quartet of voices with your fingertips.

I would like to thank VK for the wonderful sales assistance, service and prices. This was my first purchase with you and it won't be my last. I only wish I'd discovered you years ago!

I had two Grammy wins this year - Ray LaMontagne & Carolina Chocolate Drops. Both made with help from Vintage King!

In almost 20 years in Pro audio buying, never did I receive a unit so well packed and exactly as described. Works flawlessly. The whole process has been so smooth. I will never hesitate to do business with you guys in the future and will recommend you to everyone I know.

This was my first experience buying something from Vintage King (although I surf the "used" categories on the website frequently!), and, despite being on the other side of the world, I had absolutely no trouble and everything went very smoothly.

My experience with Vintage King was excellent. The order was here fast considering it was out of stock. The sales person had SKB send it to me directly and I couldn't have been more pleased.

From the minute I placed my order I was kept well-informed through each step in your process. Even though I was buying a comparatively modest piece of gear, your attention to detail made me feel like I was purchasing a six-figure mixing desk.
