Sorry I wasn't more specific. I don't think Sweetwater employs any techs to repair basses. However, why would they ship out an instrument that is not playable? It only damages their reputation. That's why they make a big deal out of their 55-point inspection. Even without techs to do repairs, why wouldn't they disclose that this bass needed tuners and offer it for 25% or even 50% off instead of just 10%?...or just send it back to Fender as defective? I've owned three Squier basses in the last eleven years. This one is the only one I've had tuner problems with. I agree--one out of three is too high a percentage. This is the only Demo I've bought from Sweetwater, where I've been a customer for many years. Since this is a thread inquiring about buying a demo from Sweetwater, I guess I'd have to say simply that I did it once and received a bass with an undisclosed issue making it unusable as it was, so zero for one when it comes to receiving a usable demo from them. That's too small a sample size, but it does make me hesitant to try it again. Because of a good deal from a friend, I was able to repair it for the cost of the $50 credit they gave me, so I came out OK.
They do have techs. They can do a full plek or setup before they ship. So yes. They have guys that could have replaced your tuners.
But again. I don’t quite agree that a squire with bad tuners is defective. That’s like saying a new car, that costs under 15k and has a slow 0-60 is defective because it’s slow.
You get what you pay for. If you want to pay Squier prices, you aren’t guaranteed quality parts. I feel like “buy a squire and replace the tuners and pickups” has been a pretty standard trope since the 80s.
