About The Pedal Creators

Everyone can build excellent boutique guitar pedals. Everything we do is to make that experience more accessible and user-friendlier. The Pedal Creators series are the best and easiest to build PCBs ever. Including most resistors and capacitors already soldered on board as SMD components, leaving the key values for you to experiment and craft your own tone. Now you can build a pedal you are proud of in less than an hour without any previous experience. What are you waiting for to become a Pedal Creator?

The Pedal creators – key features:

• Easy to build, no previous experience required. It’s like Lego for musicians.

• Fast assembly finish a pedal in less than an hour. Play your favorite record and enjoy the ride along.

• 100% mistake-proof. Even my grandma can build one while she cooks.

• Build your own boutique pedal. Experiment with different values and make the pedal you always dreamed of.

• Easy to scale. Turn your passion into a money-making machine.

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!
