This comp has been on my board for a while now and I may regret posting this. However, things change and looking for something else in the world of compression. If you're looking for a transparent comp that just adds a slight warmth to your tone, look no further. Anthony Sallee (touring/session guy out of Nashville) turned me onto this thing and it's been a great investment. Easy to use as it has two knobs, comp and volume. Do you need this on your board? The answer is yes! Also, yes this is on a board and yes there is Velcro. I can clean it off if needed...So jump on it TB!
