Green Citrus - Matamp-in-a-box

This one comes growling out of the DIY archives to bite your face off.

This circuit was put together by Branimir Bozak over at DIYStompBoxes, and is based on another DIY project by Paul Nelson - the Citrus Graphic Mk2. The latter aimed to recreat the tone and response of Orange amps, so it was a small step to turn the circuit Green. Rumour has it the same circuit is used in the Midnight Amplification™ Holy Mountain©, but we can't confirm that.

Of course, you aren't going to get a GT200 in your Fender Sidekick, but if you're looking to recreate the characteristic growl of a Green head this is a good place to start.

We've designed the PCB to take through-hole or SMT FETs, as through-hole are getting more scarce. SMT parts aren't exactly simple to work with, so you need to be confident in your abilities before tackling them.

You'll need a mutimeter to bias the FETs properly.

The kit is supplied with vertical-mount pots which have round shafts, so you'll need set-screw fitting knobs.

If you want the PCB without parts there's a link for that at the bottom of the page.

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 available as an option with full kits, and will not take a battery. Knobs are not included.

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

Desert legion smoke-covenant is complete
"This thing rips. My band has a good number of pedals in this wheelhouse (many also from FuzzDog) - RATs, Russian muffs, Acapulco Gold, Meathead Deluxe, Sputnik, Pharaoh, etc. - but this one still earned a place on the board. Enough gain on tap to use alone, or you can keep the gain moderate and boost it. Cool cool." Dan - 16 February 2019

Follow the smoke to the riff filled land
"First off my only complaint is the holes on the enclosure were slightly off..other than that this build is amazingly close..my 3rd build from fuzz dog and never any problems and always arrives speedy quick..this pedal is suuuuper versatile..wasn't expecting all the tones from this ..I'm ordering another one" Quinn - 11 February 2019

Drop out of life with gain in hand
"Been waiting forever for a kit like this! Really does a decent job nailing that thick, punch in the face sound of a overdriven green or matamp stack. It's very very dirty, the standard build is very doom friendly which I love. But I found that using a J201 in the first fet spot cleans it up just a bit and makes it react a little more like a 70s amp. There's still the boost stage to add gain and it's easier to stack pedals. I'm so excited about this pedal I might get another just to make a standard build and one to mess around with different settings." Jonathan - 06 October 2018
