Polytune

An incredible idea that for years proved elusive.
How can a guitarist tune all six string at once? You can't, duh.

We've been made to strike each string in turn, tuning it...tweaking a bit more, muting the string before proceeding to the next and so on. What has differentiated most pedal tuners up until this point has been speed and accuracy. Strobe tuners are the most popular and the faster the strobe can respond to changes in frequency, the faster one may tune up.

Then in January I heard some buzz about a tuner that allows you to strike all six strings at once and it will show the status of each string, flat, in tune, or sharp.
I plugged it in and strummed the open fretboard - an there it was, the low 'E' and the 'A' were flat.
Nicely done. Striking that low 'E',  Polytune switches to a more normal needle strobe mode. I almost wish there was a switch to activate one, both or the other mode as I found it disconcerting to switch to the needle.
But it does have the ability to show me at a glance which strings are out of tune and which way.
It may take some getting used to, as my current tuner is a circular strobe, and wickedly fast.
We'll see.

Less than $100.

Dunlop wedge picks. Good Gosh but I love these picks.
Dunlop Stubby Picks
$3 gets me six. And they are durable. I haven't worn one out as of yet. My gauge is light so that is a factor but my previous favorite picks (Gibson Heavy-Jazz Teardrops) wore at a much more noticeable rate.

Nickel strings. Not nickel plated or coated. Pure nickel strings. $6 or so for a set. They are much more resistent to corrosion and they have a  very bright sound that lasts for a really long time. I used to change string every two to three weeks. I find my self going for a month or more and I play a lot.
I generally will take any brand with the exception of D'Addario. The last three sets of D'Addario strings I purchased were flat out awful. A 'B' string broke, they lost brightness inside of days instead of weeks and they have resorted to some really cheap packaging that tends to make a mess in my gig bags.
