Description
Click Here for our New NostalgiTone Compressor w/ on-board Attack Switch
This is a Modified Ross Compressor. Based on vintage designs but with enhanced Treble Response. Very transparent at lower settings (great for Gilmour solos) it can also get nice and squashy when you turn it up full for Classic Country licks or Southern Rock. Thanks to some great ideas from the likes of R.G. Keen and now redesigned to work with the excellent LM13700 chip this classic circuit is ready for modern day pedal boards. Sonic clarity with long Sustain modified to not alter your tone.
