$200 to install a set of pickups and pots, really? - ffs, he must have seen you coming man. That surely can't be the going rate in the US, right?
In the UK, an amp or guitar tech will typically have a minimum bench charge of £35 to cover the first hour's labour and this will sometimes include parts that are pennies like the odd cap, resistor, fuse etc... (I don't charge separately for anything thats under a fiver - its swings and roundabouts).
To install a set of pickups and even to install new pots isn't a massive job. Even if I took my time this is an EASY 2 hour job with a tea break and time to take a dump while reading the sports pages of the morning newspaper. So lets say it's a 2 hour job, thats £35.00 for the first hour then £25.00 for the 2nd hour and successive hours; £60.00 in total. Using XE.com, I get US$93.00
I'd be asking the guy who did this work to break down the $200 charge to do this work, it's an absolutely outrageous amount to charge for this work and especially so since the guy hasn't even installed the pickups correctly. Its amazing how many times we hear of people getting BKPs fitted and the 'tech' has installed them incorrectly. It's not like this is a tough job, its an electronics 101 type job, very basic. I'm p*issed off for you man.
