Feels Like A Real Amp
“Enhance” restores the touch, feel, and response of playing through a real amp. When the Enhance switch is engaged on the instrument input, a unique circuit is introduced that mimics the input stage of a real valve amplifier, including all of it’s non-linear behaviours and characteristics.
