i'm wondering how these horitzontal lines have been textured, it doesn't seem to have been done with a brush. Something that is also interesting is that where ever the horizontal lines converge with the logo it sort of glows/thickens.
It's hard to say, but my initial reaction is that the lines are all uniform white strokes. A dark textured layer has then been put on top and partly erased in certain areas. Then an outer glow added to the logo. Maybe some other filters applied. Hard to recreate as the designer probably just played around with various filters and transparency settings until they were happy with it
