FAQ) About shopping, payment, and delivery

Currently, it is only sold directly through the Logic Wave online store, and is not available at Amazon or musical instrument stores. Please note that purchases made on flea market sites, auctions, etc. are not covered by the warranty.

[Reasons for choosing online direct sales]

Up until now, we have received inquiries from several major musical instrument stores about handling our products, but all of them have been declined.
We have adopted this policy because we want to deliver products directly to our customers and provide solid post-purchase support, and because we want to receive feedback directly from our customers.

When shipping the product, we will include a receipt.

Please note that the receipt will be addressed to the billing address you entered at the time of payment.

Rest assured that shopping at the Logic Wave online store is simple.

1. Tap (click) the image of the product you like to move to the product page.

2. Press the "Add to Cart" button to move to the cart screen.
