The Demonfx AT-DS is an overdrive/distortion pedal that integrates distortion and boost functions. It is said to be a circuit modeled after the JHS Andy Timmons "AT+" (Angry Charlie series). The item includes the main unit, box, English manual, etc., as shown in the photos. The main unit appears to be in clean condition with no scratches. Since the criteria for judgment differ for each person, please make your assessment based on the photos. I believe the operation is problem-free. It has been stored in a smoke-free and pet-free environment. Below is information about the pedal from the web: • A clone/derivative pedal, said to be a circuit modeled after the JHS Andy Timmons "AT+" (Angry Charlie series). • It has unique features, such as a 3-way switch to select different headroom (25W/50W/100W). Sound Guide: • 25W Mode → More compressed, saturation-oriented • 50W Mode → Balance of compression and openness • 100W Mode → Wide and open crunch/distortion tendency → You can get quite different characters just with the 3-way switch. The boost is effective for light push to acceleration of drive. → Practical even on its own, such as increasing the gain feel during solos. Thank you for viewing. Best regards.
