Hi Angela,
Everything you need to know is on YouTube nowadays and I promise you’ll get the hang of it in no time. One of the reasons people get really sucked into guitars and playing them is that it’s so interesting and gives you lots of knowledge about stuff that you otherwise wouldn’t find out about. Even down to woods, wood finishing, growth patterns, all sorts. It’s a bloody brilliant hobby!

aww thats nice

A relative plays, & builds guitars as a woodworking hobby.

I've been inspired to get an electric.

Deceptively technical, you can really tweak them to produce a given sound.
Boxes and pedals further expand their capabilities.

Looks like your son found an expert mentor!

That's quite an education Angela ;-) If you don't have a tuner, they are handy to have. There are battery ones, and a USB rechargeable is more up front, but in the long run not needing to buy replacement batteries it works out.

Is his guitar acoustic or electric?

Always happy to try and help. Sorry it took so long on H's one 😂

Glad that your son learnt how to re-string his guitar.

Replacing a string is a necessary but basic skill for any player of a guitar, violin or other stringed instrument, but is hardly engineering. Besides, the engineer designs things, not mend 'em.

Fitting a string should not need tools. After all, one day he may need do that on stage!

I can see adjusting the bridge would need tools and some technical knowledge of the instrument, though screwdrivers and Allen keys are basic, universal tools; feeler-gauges not very much less so.

The difficult bit should be the tuning and playing.

I have a lot of sympathy for your son, and you, in needing seek help to replace a broken guitar string. It seems very many people now find it hard to see how to perform basic practical tasks by examining them - and I don't think it's their fault.

That's so great so nice of @OldBrit sharing, and I bet he enjoyed sharing also. Learning an instrument and falling in love with it is a gift that lasts a lifetime.

I have taught many young people a proper set-up technique & how to service their own guitars. Here in the states they charge about $75 dollars per set-up & re-string!! I teach people how to SAVE that money & keep it in their own pockets!

I've seen musician friends pretty much re-engineer instruments before playing them. It's not enough to play it right off of the rack

Ah. The Floyd Rose system, yes it's a pain. Not something I'd want to work with long term. I'm not a lead player anyway.

You are so lucky to have a friend like him close by. Learning how to restring your guitar is a necessity. Having an electric tuner is too. Hopefully you can come over more often and he can help the boys become better players. 🙂
