This really is a box which once plugged in you are really not going to switch off.
It is an optical compressor so you do not get the extreme pumping of some compressors. Also the 'chime' knob puts back some of the top end which you naturally lose with compression.
This is the second Orange pedal I have, and I have no complaints about the build, the sound or the quality craftsmanship. This is a really stunning compressor and rivals many boutique pedal costing twice the price.
OK, it is big, we are not taking small footprint pedal, but the sound quality easily makes up for the extra space on the pedal board.
I have this with the Orange Two Stroke straight after to tweak the sound of the guitar before entering any 'proper effects' (as compression and eq boost are not really effects) and the sound I am getting is the sound I always dreamed of, whether this is a cheap 90 jap-strat copy or a pricey Les Paul.
It really fattens the sound without changing the tone characteristics of the guitar.
I could not be happier.
