Thank you for viewing. This is a self-made clone of a Bootleg Rock 'n' Roll Party. It was made by someone else. High-quality parts are used. Wima and Faithful Link film capacitors, OS-CON and United Chemi-Con high-grade electrolytic capacitors, Amtrans ARMT (carbon-coated) signal line resistors, and a Takachi case. No printed circuit board is used; it is hand-wired point-to-point. Solder is Oyaide SS-47. An internal battery cannot be installed. The power jack is on the top of the unit. The LED is white. The pots are mounted directly on the board, so the board is firmly fixed to the case. It's the so-called MXR size. It is boosted to 18V internally. It is a used item, but the condition is very good. There are some minor scratches, but it is a handmade effector that I purchased previously. There are no problems with the operation. If you have any questions, please contact me through the comment section.
