You can download my patches onto your POD HD300 using Line 6's HD Edit program.
Keep in mind the patches were made for my Fender American Stratocaster with stock single-coil pickups. Depending on your guitar they may sound different. Try adjusting the guitar volume and tone knobs to find the sweet spot.
Two fun things to play with:
Change the Twin patch to use an Overdrive (Drive: 48%, Output: 40%, EQ to taste) for a great overdriven Twin with loads of harmonics. Change the Marshall patch to use a Fuzz Pi (Drive: 68%, Output: 50%, EQ to taste) for a different flavor of lead tone.
