Since Reverb is a marketplace full of unique sellers, the Reverb staff is unable to answer questions about specific items.
What you'll want to do is click the "Message Seller" button on the listing to open up a direct line of communication between you and the seller. The majority of sellers on Reverb respond to messages within 48 hours.
