So I got a nice old EM today from @lukewells as a project (built the same year I was born!). It's going to need a side panel on the cabinet replacing, so I'm thinking I'll replace that, along with a bit more cab work, and then re-do the artwork. I've read that one way to re-do the artwork is using a mylar stencil, using something like the below to cut (actually, quickly melt) the mylar stencil. Does anyone have any experience/tips about these - ideally I'd like a recommendation on a make/model and user tips
