The open feel of the PAF Pro and FRED is matched with masses of midrange and bass for a tone that really kicks hard in The Tone Zone. With lows, mids, and highs all boosted, it feels like you've turned up an extra set of tone controls. It adds extra dimension to the sound of your amp. Notes seem to get bigger after they're picked and the aggressive tone has plenty of drive in all the right frequencies, more than enough gain to push preamps and power amps, and sensitivity to pick attack that gets the most out of any style from metal to blues
