I have been using Gruvgear products for some time now. I mainly use the string dampener on my 8 strings when tracking in the studio, for the obvious reasons of eliminating and accidental note rings that may occur, which could ruin a perfectly good take. Of course this means it gets a lot of use - but the only problem I have found with this is because of its construction, it seems you constantly need to buy new ones to obtain the same quality of dampening you had from new.
I still would totally recommend the product as it does exactly the job it says ‘on the tin’, but it would also be great if they could make a more durable version that doesn’t start to fray or deteriorate after only a couple of weeks. Other than that, I live them and they also look stylish and suited to any guitar.
