I have a Fender Hot Rod Deluxe, and I'll normally play it for around 3 hours a day or so.

However, recently its been making these small but audible buzzing noises, even during the clean channel. This normally happens after about 30 mins of play. Is this a sign I need to change the tubes?
Could just be some loose screws or something

You'll find whisky very different, but try it and you'll grow into it, soon you and whisky are one, but still two, lovers dancing across a frozen lake under moonlight, wrapped in honey and warmth.

Sums up whisky perfectly
