After stomaching through some of the track elklandercc sent me, I'm still unsure as to what that "beeping" sound you're talking about is. Unless, you're talking about that harmonic tone that comes through on some notes (higher pitched pick beep type overtone). That is achieved through using a guitar with harmonically rich pickups, and an amp that lets the these tones through. The 6505 is an excellent amp for that type of music and tones. To get those tones to shine through though, you need to be able to play very cleanly. The best way to get there is to practice your lead playing through a clean channel, so you can clearly hear each note that you play. Pick technique helps in this as well, but I don't know how to explain that to you :o
