Meris Unveils The Hedra Pitch-Shifter Pedal

Meris have unveiled a new addition to their pedal line – Hedra, a three-voice rhythmic pitch shifter pedal which provides a unique combination of pitch shifting and delay effects, allowing you to add some truly lush sounding eternal soundscapes to your music.

Featuring automatic pitch correction with chromatic or key-driven harmony (with selectable scale types), the Hedra let’s you add three harmony voices to your signal, all with dedicated pitch controls for common intervals (3rd, 5th, 7th & Octave). Combine this with tap tempo synced delay for each voice and four individual delay configurations with feedback routing, and you have a pedal that’s capable of taking you into a whole other musical dimension!

Not just intended for guitarists, the pedal’s switchable headroom means it can take instrument-level or line-level signals allowing you to use it with keyboards, synths, drum machines etc. It also responds to MIDI control via note on/off messages giving you more control over the shifted voices.


• Individual controls for Pitch and Time Offset for each voice
• Chromatic or Key-Driven Harmony – with 6 selectable scale types via ALT control
• 4 Delay Line Configurations with unique Feedback Routing
• Unique Keyboard Control via MIDI – puts a live quartet under your fingertips
• Micro Tune – creates gentle chorus-like detuning, classic studio fattening and extreme warping
• Glide Mode – slides between pitches at the speed you choose
• Choose to sweep through Intervals smoothly or hard step for dramatic pitch effects
• Switchable Half Speed and Auto Swell for advanced textures
• Digitally controlled Analog mix control
• Stereo input and output
• Switchable input / output headroom level for Guitar or Synth/Line level
• Expression pedal control over all parameters simultaneously
• Presets available via external 4-Preset switch or MIDI

Introducing The Dark Blood Distortion Guitar Pedal by KHDK

The Dark Blood is the new pedal from KHDK. The partnership between a certain Kirk Hammett and his business partner David Karon.

Combining solid state and mosfet technology this pedal delivers an amp like sound with plenty of gain and a powerful mid heavy tone.

I tried this pedal through a speaker simulator straight to the desk and through the clean channel of my old 6L6 loaded 120 watt valve amps clean channel and it performed exceptionally well in both circumstances.

You can trust me when I tell you there is plenty of gain on tap. Keep the gain low and the Doom counter clockwise and its tight. Perfect for those heavy riffs. Increase the gain (use the gate to keep the background noise in check) and the clarity remains which is not something that can be said of all pedals of this type. Turning the Doom clockwise increases the bass and gives you a spongy amp like feel under your fingers, perfect for those blazing fast lead runs and long sustaining notes.

The treble control is a passive low pass filter and is wide ranging enough to let you tailor the top end from bright and cutting to a more mellow smooth tone.

The HI/LO toggle switch offers two types of gain. LO is geared more towards rhythm while the HI mode adds compression giving sustain to your lead tone.

The aforementioned gate is an excellent addition and careful use keeps the background noise to a minimum without impacting on your tone.

Yes this pedal can do metal standing on its head but its crunch and lead tones really are wide ranging enough to cover many tones outside of this genre. There are plenty of tonal options from the wide range of controls on this pedal. If you are looking for a distortion pedal this is definitely worth adding to your list of must tries.

The one thing I have to say about the KHDK range of pedals is that they are well designed and perfectly executed. You don’t have to be a Kirk Hammett fan to want one of these pedals you just have to be into good tone……
