Hmm.
IMO I'd be mentally prepared to pay another guy 25 bucks for ANY job requiring electronics on an instrument.
1. Electronics for me is rather hard to grasp.. I'll admit it, and I'll leave it to the pros.
2. because of the above, when I pay them well I expect the job to be well done.
3. I'm not a cheap person, and I don't look down on others, thinking that they are cheap.
Only one time I didn't pay for an electronics (crackly tone pot) job was when I brought my guitar to the shop, they lost my tuner (apparently one other customer stole it.. I dunno how but that guy stole it) and the cost of the tuner offset the cost of the job. :?
Moral of the (sorry for being so long-winded) story is: don't be so damn cheap.
