Project overview
The fuzziest and thickest pre-amp you always wanted, now in a pedal format. Inspired by Green amplifiers, the Green lemon is Green as the leaves that inspired the most famous stoner riffs. Do you dare to try this blasting beast of doom?
Introduction
Green amps are the holy grail of Dopesmoker’s tones and a must on every doom-stoner player. These amplifiers are well known for their brutally thick fuzz tones and growling bass; however, it’s almost impossible for you to get to plug your ax of doom into one of these heads as they are as expensive as rare.
With the Green Lemon, we wanted to fix this by making this fantastic circuit available for everyone in the DIY world by designing a JFET version of this tremendous pre-amp keeping the tone and the main structure
and functionality of the original tube amplifier.
The signal path follows the same order, featuring a Baxandall tone stack between the gain stages delivering its massive trademark sound.
If you love these JFET doomy pre-amp stompboxes, don’t forget to check out our Lemon Rockverb, Black Sun of Doom, and our JM 1800 (add links to each). You will be blown away by the jawbreaking power of these circuits. Only available on DIY format… for now!
You can also check the SMD version that comes with most resistors and capacitors already soldered on board as SMD components, making it the best and easiest to build PCBs ever.

Very surprised there are no reviews on this one. This circuit absolutely blows the Midnight Amps Holy Mountain out of the water! Both punchy and growling at the same time and the boost knob is the secret weapon, allowing you to really dial in and shape the overall dirt and feel of the Gain knob. This does the stoner/doom thing really well, but also so much more. Hands down this is one of my favorite preamp/dirt pedals. Even sounds great into the dirty channel of my Rockerverb and hardly any pedals play well with the dirt channel. Kudos to PCBMania!!
