Got a question for y'all: I'm thinking of ordering a hipshot bass extender for a 2012 American standard Jazz bass from bestbassgear online and would like some feedback about them from anyone who's used them: 1. BT8 is the correct model I believe. Anybody confirm? (I will with photos anyway before I order it). 2. How well do they function? Accuracy of intonation, smooth action, don't wear out etc? 3. Do they look stock from the front? 4. Important: I don't think I had to pay any import duties to Canada when ordering things delivered through USPS. Just don't want to have a rediculous figure tacked on and you never know nowadays. After all, it's made out of steel . Any experience? Cheers!
