Schaller is the go to for me
Pros.
You can buy this separately and use the same strap for different instruments
Cons.
You need to know that 3,5mm 4,0mm and 4,5mm are Not compatible.
Therefore you need to measure the thread on your guitar before you order. This takes away 1 star for design.
1 star overall is taken away, because this is not made clear for the costumers.
Overall.
Trying 3 different brand’s, this is the most expensive.
But also the best I have tried, and I will buy it again.
