EarthQuaker Devices Bows · Guitar Effect

If you wanted to produce the then new, cool distorted guitar sounds in the late 60s you had only 2 choices, you either used a fuzz, or you used a treble booster, a primitive preamp actually should raise the high frequencies, but also clearly raised the guitar signal and thus the input of the amplifier was overdriven. Musicians like Rory Gallagher, Tony Iommi, Brian May and many others used this trick for their distorted sounds. The EarthQuaker Devices Bows falls into this category. Core of the circuit is a super rare NOS OC139, a germanium transistor with a housing made of black glass! The Bows raises the output of the guitar and the amp's preamp is "blown". The guitar sound gets a significant increase in the middle, regulates it down the volume control on the guitar, you get a super-clean, glassy sound. The Bows offers besides the classic treble boost also Full Range Boost without raising certain frequencies.
