EPic Boost

Clone of a very neat little transparent boost, based on the pre-amp section of the EP-3 Echo Machine. The circuit is actually nothing like that pre-amp, but it does sound like it.

The circuit has Bright and Fat modes, selected with two switches. These can be internal DIP switches, or external toggle switches.

If you do go for toggles they are board-mounted for minimal wiring and easy enclosure mounting.

Combine with a Power Pump if you want to run it at 18v from your 9v supply for more headroom.

Partial kit: PCB, all board-mounted components, pots.

Full kit: As above, plus footswitch and appropriate daughterboard/components for your selected bypass type (see Downloads section for details of those), jack sockets, DC socket, battery snap, hook-up wire, LED.

Enclosure (pre-drilled) is only available with full kits, and will take a battery. Knobs are not included.

Builds are only available with full kits including enclosure and vertical-mount pots. Please choose appropriate knobs.

Difficulty: Easy

PCB size: 50 x 35mm

Knobs required: 1

Enclosure: 1590B

Direct-Connect compatible (4-way)

If you want the kit pre-built you must add the enclosure option below and select your knobs in the Components section. Check Specials for powder-coated enclosure availability.

One knob wonder 5 product stars
"Great relatively easy build. Well designed and sounds fantastic. This was my first fuzz dog kit and worked straight off the bat. I normally don't run it too high but sounds good beefing up single coil pickups, coaxing a bit more gain out of my Klon clone or coupled with the fuzz dog filth fack for extra thickness. I chose the option to have the switches on the front. Their impact is very subtle tonaly. Very happy with this pedal." Greg - 03/07/2015
Great pedal 5 product stars
"This is my second build. Really enjoyed building this one (+ finding and correcting my inevitable mistakes). They're not lying when they say that the switches are subtle but it sounds great even with my SS amp." Tom - 01/11/2014
Epic boost is epic. 5 product stars
"Built this for a friend who wanted to utilize the potential of a Selmer Treble & Bass 50 watt. It sounds absolutely wonderful. Pushes the amp into sweet distortion without colouring the tone. I also tested it on my EH 22cal pedal sized power amp and it sounds like a overpriced boutiqe amp ..." Tjærand - 08/01/2014
