Catalinbread Epoch PreThe only Preamp Buffer you'll ever need. Our Epoch Pre was modeled after the exact preamp circuit from the original EP 3, from the 22v power supply to the JFET preamp, to the circuit loading contributed by the echo function. Not only does it provide boost it acts like a mastering plug in on the master fader making your whole pedalboard sounds bigger, lusher, wider, the Epoch Pre can bundle all the frequencies without squishing them like a compressor!
