This is a booster/distortion pedal featuring a Tube Screamer-style booster, a noise gate, and an EQ switch for Djent. Placing it in front of your amp will give you tight, focused distortion. While it's a pedal specifically designed for Djent, you can also create a variety of sounds suitable for solos, and it even has a MODERN/WARM switch for fine-tuning. It's got everything you need. Most importantly, it includes a noise gate, which is essential for distortion and boosters, so you can do everything with just this one pedal. Operation has been confirmed. If you need it, I can also include a 9V adapter. Thank you for looking. I will re-confirm the operation before shipping, but I cannot be responsible for any issues during or after shipping. Thank you for your understanding.
