It is an amazing overdrive, smooth and responsive, but the best feature in it is the spectrum knob.
At noon it is flat, turn it left and you have a warm mid frequency hump, turn it to the right and it scoops that mid frequencies while boosts the treble and some lower mids, very useful and clever.
If you set the drive all the way down (0), spectrum at noon (5) and level to match your guitar output, you will turn it on and off without noticing any difference in the guitar sound, completely and absolutely transparent.
Worth to check it out if you are looking for a very good overdrive.
