Give your Tele a new voice! While the 4-way Tele switch isn't a new concept, Obsidian Wire made it amazingly simple for me to add the 'humbucker mode' (both pickups in series) without needing to solder anything. Humbucker mode is punchier in the low midrange, which is great for me as a solo guitar performer, as I don't lose the richness as I do with the traditional parallel setting. Plus, the treble bleed gives me a solid tone regardless of the volume knob position. Now I want to install this in every ASAT and T-style guitar I own. I couldn't be happier!
