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.

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.

Designed for vertical mount pots (round shafts), or you can wire up normal pots (splined shafts) if you prefer.

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. The kit is currently supplied with through-hole parts.

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

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 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.

Difficulty: Medium

PCB size: 50 x 46mm

Drop out of life with gain in hand 5 product stars
"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 - 06/10/2018
