Tu veux absolument une grille métallique?
Je dis ça parce que chez Tubetown par exemple, tu peux acheter un "sample" de grillcloth de 10 cm par 10cm pour 30 centimes

“The type of cap is not as important as the value of the cap, for guitar. In an Amp, your cap type is much more important, as the signal is being passed through the cap all the time. In a guitar, you’re not hearing the cap itself, you’re hearing what the cap is impeding”. Lindy Fralin
