Questions from internetland: amps and mics for lead guitars?

Reader and musician/music enthusiast Jordan Hoek chimes in with a question:

I really like the lead guitars in workers theme, undue strain, and broken wheel. What amp do you use, and what kind of effects do you use? Could you go into more detail in how you record it? Just stuff like, mic positions you generally use, how loud you put the amp, and whatever else.

I almost never use amps or mics for lead guitars! I know it’s sacrilege, but I have a lot of fun simulating amps. There’s such a diverse range of tone you can get with a few effects and adjustments. I’ll tell you one trick that I use a lot, to make it a little more “live” sounding: I use a good deal of compression BEFORE the distortion and/or cabinet simulator. This gives it more sustain and almost feedback-y sound. Also you can have more sustain with less actual distortion this way, and have long, sustained notes without turning the tone of the guitar into a total square wave (i.e. still have some guitarish “character” to it and not need to make it “metal”).


My current chain of effects for lead guitar tracks in Tracktion: multiband compressor set to only compress the midrange, resonance filter (with resonance set to zero) to act like a noise gate with a more interesting roll-off at the end of notes, an equalizer to give a pre-distortion midrange boost (inspired by Brian May), the amp simulator (includes distortion), and finally, subtle touches of chorus and reverb.

For Workers’ Theme, since it’s a remix, the lead guitar was done within the last year or so and I used a special stored combination of effects I have set up within Tracktion. There’s a YouTube video of me playing it, too, and I punched in a short section using slide instead of fingering… and I had a capo on the first fret, because I guess I wanted to be able to occasionally hit open strings, and the music is in F minor.

For the last part of Undue Strain, I actually used my Crate amp (80 or 100 watts, not a huge amp), probably at a medium-ish volume, and an SM57 hanging in front of it. Using an amp is extremely unusual for me! This was about ten years ago. I’ve never been careful about mic placement, so I’m not the person to go to for tips on that; I’m guilty of just putting the mic “somewhere close” and then using EQ to get the tone where I want it.

For Broken Wheel, I was recording on one of those digital portastudios, and used a built in amp simulator, but probably tweaked it a bit. And I think I used one or two foot pedals before the input; I know I at least had a slow phaser on it. Sometimes it’s interesting to put an effect like that before the distortion, because it puts some randomness on which harmonics get emphasized by the distortion. I did takes both with a slide and with regular playing, and made a composite from bits of both. I remember sort of trying to go for a “Momentary Lapse of Reason” sound there, though I don’t know if I pulled it off. ;)


How I simulated amp tone in the mid to late ’90s

Before I had access to good amp simulator effects, I got reasonably passable tones just using an equalizer after the distortion. The main thing you have to do is completely filter out the upper frequencies, anything over 4K or so (so it doesn’t have that “buzzing bee” tone), and scoop out a big chunk in the middle somewhere too, so you’re left with an emphasis somewhere in the higher midrange (anywhere from about 2K to 4K), and then another lower one somewhere. Sort of an “M” shape. Even using a wah-wah pedal left in one position will kind of give you an interesting tone.

Thanks, Jordan, for letting me post your question!

P.S. - in the early 1990s, when I was struggling through my first solo project, I borrowed one of these and used it for most guitar parts.
