Thank you for viewing! This is a Japan vintage YAMAHA PSE series chorus pedal. It is said that Mr. Masanori Noguchi of Casiopea used this chorus pedal back then. True bypass. This item has been repaired. The effect wasn't working, but the cause was some solder cracks. The solder joints in those areas have been redone, and it is now operating normally. Furthermore, the following modifications have been made: ○ The DIRECT OUT has been changed to a DC jack, allowing the use of a standard 9V adapter. BELDEN 8503 wire has been used for the added wiring. ○ The LED has been replaced with a blue one. It also blinks (faintly) in time with the SPEED knob. ○ All electrolytic capacitors have been replaced with new ones, and the power supply section's capacity has been partially increased to improve sound quality. ELNA electrolytic capacitors have been used. (Photo 10) The land on the red circle part was peeled off during the replacement, but it has been addressed by point-to-point wiring and is operating normally. ○ Bypass capacitors have been added to the power supply section to reduce noise. It's an analog-like chorus. The solder used for the modifications is Japan Almit KR-19RMA for the main power supply section and KESTER44 for the rest. Operation has been confirmed with an adapter and a 9V battery. I do not have the dedicated power supply, so I have not been able to confirm it. There is no scratchiness in the knobs. Body only. I will do a simple cleaning of the jacks before shipping. Thank you. Color: Black Type: For electric guitar Effect type: Chorus
