made it sound so much better (to me anyway). It's SE HD with the mid boost, when I got it it had only a cap on the volume pot as a treble bleed. I can't really explain exactly what it was about the tone but something just didn't sound right about the guitar. I always had to jack around with the amp when I used it when I really never turn the knobs much at all for any other guitar whether strat or humbucking equipped. I said something about it on another forum and John Suhr suggested replacing the single cap (I'm also unsure of it's value) with a 680pf cap and a 150K resistor in parallel. Man, it made all the difference, the guitar sounds so stinking good now. And the best part, the parts cost less than a buck.
