Peter: One song I really enjoyed was ‘Come On Baby.’ It reminded me a lot of your self-titled album, that kind of open, almost dry guitar sound. Are we hearing single coils on that song?
Satriani: It’s funny you should ask that because I’ve done a lot of interviews and no-one really asked me about that particular technical aspect, but I was just using my usual JS1000 with the coil split feature, just lifting up the tone control. You can hear me shifting pickups during the solo. I swear, you can even hear the switch as I go between, not only the single coil, but I’ve also got the high pass filter engaged by lifting up the volume control. So I’m playing with starving the amplifier, which is set up to give me a ‘classic rock’ level of gain, but I’m starving it of information. I’m using the single coil, which lowers the output and gives it a less midrangy sound, and by using the high pass filter in there I’m stealing more low end from it, so the amp isn’t really breaking up that much and I get a smoother tone. And that’s all I was using. It’s funny, I did the first clean guitar in the left channel, one pass, then on the second pass I did the right channel, then I went back on the left and put the gains up a little more, then I did guitar number 4, then I did a guitar for the middle, and I didn’t really change much, I was just playing around with the volume control and the high pass filter.
Peter: It’s such a lost art, I think people get so bogged down with all these effects and things, that you forget you have these controls on your guitar which do these amazing things.
Satriani: Yeah. I was playing through a prototype amp which an older style, with 6V6 tubes in it, so it’s a vintage style smaller head. Those things are basically Class A designs, and they really react to what’s coming to the input. In other words, what you’re sending into that input jack, which means, as you said, playing with the volume control really changes the nature of the amp, and you can get hundreds of tones just by playing with the volume control.
