I had no knowledge of any potential perception of 'brand disloyalty' (not that such things terribly concern me; its guitar equipment, you dont marry the stuff), but I think its most decent of you as a high profile guitarist to come on the boards and make a statement clear things up.
+1 to Tim and the BK team being second to none to deal with. (Edit: in the pickup world at least; Bob Johnson of Legra guitars is The King of customer service, but getting bespoke guitars and handmade pickups are a bit apples and oranges; the BK crew are without peer in their field).
