ADG announces new Meris Hedra pedal

Pedal specialist Audio Distribution Group has announced the launch of the new US-made Meris Hedra Pedal, billed as ‘a 3-voice rhythmic pitch shifter’.

ADG says the Hedra adds three harmony voices to an  instrument and with Tap tempo synchronised delay available for each voice: ‘…this beauty far transcends the realms of standard pitch-shifting. In addition, pitch glide, micro tuning, 4 individual delay configurations, adjustable pitch correction and midi keyboard control all combine in making Hedra an instrument and sonic experience like no other’.

The Hedra can be used as a standard chromatic pitch-shifter, or users can get considerably more complicated by using its six different scales and wealth of rhythmical subdivisions. ‘Now turn up the Glide control and hold down TAP for auto-swelling synthy portamento shifts – or bump up the pitch regeneration – and you’ll be floating away on clouds of shimmering sci-fi effects,’ ADG enthuses.

The Hedra is not limited to just guitars, in fact it will work with most instruments or any line-level audio signal.

‘Whether you choose to totally transform your beats on a drum machine, harmonise vocals or completely alter additional synths, loops or any other type of audio, Hedra’s advanced pitch-shifting palette is sure to transport you and your sound to entirely new sonic worlds’.
