Product Details
✓2-IN-1 TUNER & ISOLATED POWER SUPPLY: Combines a fast, accurate chromatic tuner with an 8-output isolated power supply in a single pedal—saving precious pedalboard space while keeping your signal chain clean and organized. The rapid tuning algorithm ensures responsive note detection for both guitar and bass.
✓8 ISOLATED DC 9V OUTPUTS — 2×500mA + 6×100mA: Six 100mA outputs handle standard analog pedals with ease, while two high-current 500mA outputs power even the most demanding digital effects units. Isolated outputs eliminate ground loop hum and unwanted noise. Includes 8 DC power cables and 2 polarity-reversing cables for maximum flexibility.
✓LARGE, BRIGHT LED DISPLAY WITH TRUE BYPASS: The oversized LED screen stays clearly visible in any lighting condition—from dark stages to bright outdoor performances. True bypass switching preserves your guitar's natural tone when the tuner is disengaged, with silent on/off switching that won't disrupt your performance.
✓ROAD-READY ALUMINUM ALLOY HOUSING: Housed in a rugged aluminum alloy casing built to withstand heavy stomping on crowded pedalboards. The compact design (218×140×67mm) integrates both tuner and power supply into one unit, eliminating the need for a separate power brick.
✓QUALITY YOU CAN TRUST – BACKED BY REAL SUPPORT: Backed by JOYO's decade-plus reputation for crafting innovative, budget-friendly gear. Package includes the Power Tune pedal, power adapter, 8 DC power cables, 2 polarity-reversing cables, and user manual. If you experience any issues, our dedicated support team is ready to assist through your Amazon order page.
