I purchased this pedal about a year ago at a musical instrument store in Tokyo and immediately put it on my board. It works perfectly. There are some scratches and dirt from use, so please refrain from purchasing if you are concerned. Shipping is included. I thought it was a pretty excellent SCH-1 clone. The new price is about 35,000 yen. The following is an excerpt from the manufacturer's comments: This is a chorus pedal that reproduces the Vintage SCH-1. Based on a classic analog chorus using BBD elements, it has been reconstructed for practical and versatile settings. It features a DEEP switch and a LO-PASS switch, allowing for unique sounds. In addition, the MIX knob, which is not found on the original unit, allows you to control the effect balance, making it possible to adjust from effective sounds to sounds with a solid core. The ZAC-1 also uses Toshiba TA75558P for the operational amplifiers in the signal input/output stages, and uses NOS parts such as transistors and diodes to inherit the thickness, richness of overtones, and charm of the Vintage pedal's tone. (NOS parts may be changed without notice due to availability) By using modern parts in appropriate places, noise reduction has also been achieved. Enjoy the warm and full chorus sound unique to analog circuits. Requests for handling ・Please use a 9 V center-negative effector power adapter. Batteries cannot be installed. ・Due to the enhanced BBD protection circuit and stabilization, stable operation will be achieved 5-10 seconds after power is turned on. ・Do not wipe the enclosure with disinfectant, ethanol, etc. This may damage the paint.
