Bought these to replace the stock ones in my Laney Cub 12R, which were making loud 'popping' noises.
No issues with these in the four or so years since doing that.
I also couldn't hear a difference between before and after (except the absence of the popping noises!) - at least on the Laney it seems not to affect the tone too much.
I'd definitely recommend these, even just to keep as spares, especially because getting these ones from Thomann is significantly cheaper than anywhere else, at least in small quantities.
