Evolution Orange Underdrive（EOU）提供了一种新的方式来接近你的音色。现在你可以从你最喜欢的过载失真中获得更干净的音色，而不是过度放大你本来的干净音色。那个我们称之为衰减性过载。
Evolution Orange Underdrive（EOU）并不是为了从失真的声音中产生一种纯净的声音，而是为了通过力度和亮度控制来制造一种不那么扭曲的声音。
Evolution Orange Underdrive (EOU) offers a new way to approach your tone. Instead of overdriving your clean tone, now you can get cleaner tones from your favorite overdriven tone.That is what we call underdriving.
Evolution Orange Underdrive works really well with vintage single channel amps that sound great when you push them to overdrive. When you turn down the volume from your guitar to clean that tone, the sound often gets a bit too dark and the clean tones are not as good as the overdriven tone.
With EOU you can tailor your cleaner tone with the four pots. The Evolution Orange Underdrive works by lowering the midrange as that is where the overdrive mostly is. You can dampen the amplifier input with the EOU’s Volume control and then set the Bass and Treble to tailor your clean tone. EOU can also be used to boost the mids by setting the Midrange and Volume up.
