• U.S. customers, please note: Due to Reverb's rules, I need to ship this item to the U.S. by courier (likely UPS). The cost is higher than normal BUT it includes $100 insurance AND all taxes and import duties pre-paid. No taxes will be due at the time of delivery. This is a substantial savings to our U.S. customers as the U.S. Customs is now charging $33.58 MPF (minimum processing fee) alone.
