Description

Edit description

A realization of our own inspiration to combine a Ross Compressor and an MXR DynaComp (hence the name !)

The Dyna-ssoR can be used, either as a "squashing" compressor for tight single-coil-fuelled funk grooves, or as an infinite sustainer for soaring, overdriven humbucking tones.
