i just made 8 JTM45 lead presets, and i have to say that amp model is cooler than i remember. very touch sensitive.
i based the first preset off a video of Joe Bonamassa playing a reissue amp, the rest are different cab/mic variations.
try the grey compressor as a boost...way cool sustain.
adding the presets to the superpack/low gain folder now. allow a few minutes to finish uploading.
