From the vendor
Project overview
If life gives you lemons, make some juicy tone! This MOSFET-based emulator of an overdriven MATAMP GT120 is the perfect solution for any guitarist’s sour note woes. With the ability to create anything from low-medium gain drive to fully saturated high gain tones, the Giant Green Lemon will turn those sour lemons into sweet, musical nectar.
Introduction
The Giant Green Lemon is more than just a fun name and a high-quality overdrive pedal, it’s a ray of musical sunshine in your rig. This Dunwich DA120 replica has been designed to bring a smile to your face and a song to your heart. With a depth rotary switch that changes the value of the output cap on the first MOSFET stage and a Baxendal tone stack between the second and third MOSFET stages that get more tonal variation, you can turn any dull performance into a juicy, musical feast.
So, if life gives you lemons, remember to reach for the Giant Green Lemon and add a little bit of musical zest to your life!
