I'm putting my Effectrode PC-2A up for sale.
Optical compressor with a tube gain stage, great for subtle compression with tube warmth, but also capable of more extreme compression for people using compression as an effect. I used this for tube warmth and old school tones with a SS amp.
It is in good shape, it has hook side velcro on the bottom,
