The Flex by Mantic is a versatile pedal with a wide range of features and capabilities. Initially released in 2014, the Flex continues to set itself apart from other PLL (phase-locked loop) pedals. It offers a wild range of sounds and controllability, creating a new and inspiring voice out of anything you put in. The Flex Pro version comes with an expression jack to control the rate of the LFO (low-frequency oscillator). It is biased to offer the most usable range of PLL sounds in a broad musical context without compromising the user's ability to experiment.
The Flex Pro features a mix control, filter range selector, and variable speed LFO for tracking modulation. It has a 9VDC center-negative polarity and a 35mA draw. The pedal also includes a dry/wet mix for added versatility and an input VCA with offset changes that drastically alter the tone based on the input level set.
The pedal is designed with the same PLL circuit as the original Flex, Flex Pro, and FLEX xs guitar pedals. It is recommended for use as an effect with quick enveloped sounds, percussion, snappy basslines, VCOs, and as an aux send, as it can create something new and exciting out of anything thrown at it.
The Flex by Mantic has notable users including Nick Reinhardt, Adrian Belew, Jack White, Justin Meldal-Johnson, Simon Francis, Claudio Sanchez, Ikey Owens, and Juan Alderete.
