The EP booster is based on an echo machine pre amp the EP-3, the chosen pre amp for many legendary guitarists. It has an FET design and a low impedance output providing up to 20 db of boost to your signal.
We have used this pedal in 2 ways. Initially at the end of the signal chain, using it almost as a buffer to boost the signal going back into the amp. When working like this it allows you to eliminate any signal lost, and gives a great clean sound when going into the amp, making it nice and punchy.
It can also be used as a solo boost, running after all the main drive/gain pedals. Here is gives a great lead tone altering the EQ to punch through a band and maintain whatever gain coems before it, only adding volume and clarity rather than changing the sound.
The pedal is almost the perfect size, with only one button and one dial, the pedal is tiny and fits in the smallest spaces. It is very solid too and doesn’t feel at all flimsy despite its size. The pedal has 2 internal dip switches too that allow for the EQ and Boost frequencies allowing you to make it either a little darker or lighter depending on the sound you are going for.
One nice feature with the EP is that you can run it either on a 9v supply or an 18v supply depending on what you want. The 18v supply is great for really shaping EQ. The 9v adaption is great for simply adding volume, the 18v is perfect to use as a buffer, adding signal and headroom back in to the amp after your pedals have sucked it all out.
Let us know if you have it and what it sounds like to you!
Pros: Tiny size; Great tones; Easy to use
Cons: None, there is nothing I would change!
