    The Balvenie is good, but it’s not peaty enough for me. Use a Laphroaig or Glenfiddich tube for an “earthier” sound. =]

    That’s about the best pun I’ve heard all month. Well done!

    My next project is likely to be a bit bigger, more like 20W than 0.5, so I fear even Laphroaig couldn’t contain it.
