This guitar effects pedal features a 12AX7 vacuum tube and offers a wide range of tones, from overdrive to saturation. It's a used item, but I think it's in good condition. It comes with the original 15V center-positive adapter, so you can use it with peace of mind. The list price was around 40,000 yen, so you can create a variety of distortion sounds. The potentiometer is the type that often gets scratchy when not used, so please turn it back and forth vigorously. I have two of the same type, and they're in the same condition, so please understand. - Model Name: Tonebone Hot British - Input Type: Guitar - Output Type: Effect Output - Features: 12AX7 Vacuum Tube - Controls: Direct, Comp, Low, High, Level - Usage: Overdrive to Saturation I bought this because guitarists like Mr. Yonekawa of CCB and Mr. Shibazaki of WANDS used it live before. Thank you for looking.
