I keep coming across this while I'm tabbing it out. Obviously the first thought is to play that bar all the way to 110, but why then do they use repeat bars and symbols in other places but the arrow here?It looks like this:

Epiphone Les Paul Standard
Fender MIM Standard Strat
Fender Deluxe Reverb
Digitech Bad Monkey
Electro Harmonix Big Muff
Ernie Ball VP Junior 250k
Dunlop Cry Baby Wah

In that particular example, a repeat sign around such a small measure would clutter it up and render it harder to read, especially if they couldn't expand the measure to fit. Plus they'd have to put "x7" or something. If they put two measures of the G and A and put a repeat sign around both then it would be easier to read, and I'd expect them to do so in any other situation, but in this example it wouldn't work out evenly at the end because it's repeated an odd number of times. You could go further and think of other things they might have done but basically the arrow was probably the easiest way for them to get their point across.

Basically your intuition is probably correct and you should play that figure until measure 110.
