The Caroline Icarus Boost draws the line between clean boost and plain boost.
This small but powerful boost pedal is perfect for all the things a booster needs to do; push a tube amp into overdrive, make a lead stand out, push an overdrive or fuzz harder, and drive long cable runs. Super clean and transparent, the Caroline Icarus Boost features a low output impedance that is perfect for driving long cable runs. From there the Icarus takes a little different road.
The Wings control is the boost level, unity being around 8:00 and providing plenty of output for any boost need.
The Sun control is unique. Since the low impedance output virtually negates the capacitance of the cables used, the Sun control actually allows for some of this capacitance to be dialed back in to bring back some of the natural warmth of the signal and reduce the possibility of the guitar being too bright and artificial sounding. The Caroline Icarus Boost was painstakingly designed and wasn 't released until the guys at Caroline Guitar Company had a pedal they felt could replace the very nice boutique boosters on their own pedal boards with.
