Valeria is a hand-made, ultra flexible analog compressor. A unique labor of love built around the legendary CA3080 operational transconductance amplifier. Valeria offers controls for Attack, Decay, Volume as well as a pristine parallel compression option, accessible through the Blend control. There is an internal input level control. Valeria offers everything from the faintest sprinkle of oh-so-subtle compression to extreme squish . And everything in between. Valeria can be operated from a standard DC 9 volt power supply, or you can use an 18 volt supply to access more headroom.
