E-BOOSTER:

The E Booster is a discrete FET preamp pedal with a low-impedance output.

The E Booster was based around the classic preamp side of an Echoplex and produces a shimmering boost tone that adds some high-end sparkle and definition. The  E Booster features up to 20db of gain on tap and two internal DIP switches to customize
the boost. One is a Bass Boost and the other is a Bright switch. This provides extra sparkle for the darker-sounding instruments
 and is great for that extra edge or shimmer. The Bass Boost adds just the right amount of low-end for single coils to keep up. By turning off the Bright Switch you can get a full frequency boost that is transparent and gives you back what you put into it. The E Booster is a versatile boost pedal with more options than it appears.

3-BOOSTER:
3-BOOST Based on FORTIN AMPLIFICATION 33 Booster - FREDRIK THORDENDAL SIGNATURE
The 3 boost is a Clean Booster effects pedal for Electric Guitar. With a level boost of up to 22dB, the  33 booster transforms any Guitar Amp into a brute high-gain wrecking ball without distorting its sound
character. A practical detail of the 33  Booster is the side-mounted
channel-switching jack.

FX LOOP:
You can use both boosts in sequence, either individually or add other effects through the send and return.
