I went today to the nearest music shop and because it's a Yamaha retailer, I asked just for fun that do you have any Yamaha Hex Rack parts in stock. Well.. the sales clerk told me that no we don't BUT one of our employees is going to Helsinki for our shop chain meeting (Yamaha's importer's head storage lies there). I told I need HXTC clamps and can you believe! They had there four and I bought them all.. for 29€ EACH! My lucky day! I Can't be more happy! I was going to order some from ebay first but I learned a valuable lesson today: There's no point to carry coals to Newcastle! Ask the local shop before you go to order something from foreing countries.
