Re. the original pickup. Both pups in my SB900 were quite dodgy. When throwing the switches ( i have 2 pickups ) the drop in volume was so bad, it was unplayable. The volume drop was only on the D and G strings, weirdly. So i tried Rautia and sent an email, but the cost of £ to euro was exortionate .. paypal and bank wanted about £30, so i asked if he would go through Transferwise, but he wouldnt, which was strange because they're a reputable company. Used them before. He also quoted me a long delay, (2 months ) so i tried Aaron Armstrong here in the UK, and he built 2 pickups for me to original spec, and had them delivered to me in a week.
