thought I was being practical having a spare set of strings to habd

Over tightened a D string messing with tuning.

No problem

Expensive 1st lesson.

Poked through hole in saddle but went straight under the bridge rather than fishing and going over.

I quite got the hang of setting the spare amount from the pegs.

But then ruined this by pulling the spare through the tuner and then tightening.

Plus I was planning on using light strings 8-40s

Twang , twang and having cut my old strings off couldn't go back.

So total fail and ordered strings won't be here until Monday

Learnt by my mistakes and rewatched Christophers tute on string changing
