Do you play in the sun?

Do your strings only last you 1-2 weeks before loosing intonation ?

Do you play too rough and scuff your strings? 

I have been using this oil since 2012 and went from strings lasting 1-2 weeks to lasting over 3 weeks. you just dab 1 or 2 drop on you left index finger before playing, rub the lube on the strings, give it a quick strum so the excess oil doesnt mute the strings, tune up and youre set for the next hour. 

apply it every time you play. it does NOT affect the sound and helps you save some money on replacing you 3rd ( G ) String.

works on Guitar as well but DO NOT apply them to the top 3 strings, only the Nylons.
