Re: wave of high frequency
i agree, your amp settings are probably the easiest thing to change to achieve the sound you are looking for as the amp is the biggest factor in your tone chain. i find that a lot of amps (although i have yet to play through a carvin amp) have a lot of high end available. if you are lucky, it's the smooth high end, but more often than not it can easily be the piercing high end. i will usually kill the presence and turn the treble down accordingly.
however, if your amp's eq and presence are not enough, then you may want to look into pickups with more enhanced bass & mid response. maybe a breed or tone zone.
