What We Really Need
We started with the premise that most guitar players are looking for a few must-have essentials from their rigs. A priority list would include a great clean sound, a semi-distorted crunch rhythm sound and a smooth, sustaining lead guitar sound. Contemporary guitar in most genres requires at least that much variety. There are just a few essential effects that guitarists typically use, such as wah, delay, reverb and chorus. Of course, there is a nearly endless array of cool pedals that provide everything from mild to wild to crazy. We’ll stick to the basic amp sounds here. After all, if the amp model doesn’t sound convincing, no effect pedal will fix the situation.
What to Look For
One of the primary things to look for in an amp or modeling amp is convincing tone. If you’ve been on the scene for years, you’ve probably played through many of the amps that have been popular over the last 40 years, such as Marshall, Fender Twin and Deluxe, Mesa Boogie, VOX AC30, etc. It’s fair to say that the majority of these classic amps use vacuum tubes (also called valves) in their designs rather than solid-state designs using transistors and integrated circuits (IC chips). Tubes are old-school technology from the post World War II era. The thing to know is that tube amps sound unique and definitely affect your tone in many ways. It’s not just something we’ve become accustomed to; it actually does sound better to most people’s ears. Typical words used to describe tube amp tone are: warm, smooth, brown, complex, creamy and dynamic. Let’s look at that last one. Dynamic response in a guitar amp refers to the ability of the amp to respond in a positive way to changes in guitar volume, control settings and picking attack. One of the great things about a tube amp is that you can set it so you have a fairly highgain lead or crunch sound, then “clean up” the sound by backing off on your guitar’s volume control, making the sound much less distorted. Many guitarists love being able to plug directly into their amp, to set the controls and then switch between their lead and rhythm sound just with their guitar volume control. Do modeling products respond dynamically in a similar way? We will see and hear later with audio examples online at premierguitar.com.
Another thing to consider is what your needs are. For instance, if you play out live and need a lot of different sounds within your set, modeling products are convenient and much more portable than a multi-amp rig and 25 effects pedals. Of course, if you have a road crew to do the heavy lifting, then perhaps a gigantic live rig is perfect. For the rest of us, considerations such as size, weight and how quickly we can set up and load out after the gig are important concerns. This author, having played over 4000 live gigs and still counting, can attest to the fact that while it’s fun to set up an elaborate rig before agig, it’s pure torture tearing it all down at 2 AM after playing for four hours.
As guitarists, we’ve been told on occasion by sound techs (and frequently by club owners) to turn down. These folks just don’t understand that we have to turn up to 11 to get “our sound”—and they don’t care either. The modeling amp offers some help in this area, too. Since the sound coming from the modeling product already sounds like it’s coming from an amp, that sound can be taken directly from a line out and sent to the PA. This makes it unnecessary to mic a loud amp onstage, and makes it much easier for your sound tech to get a good mix out front.
The next thing to consider is monitoring your live sound. Since the modeling product is already creating the complete sound of a typical rig, including amp, speaker cabs, microphone and effects, it might be wise to listen to that signal through a full range system such as a keyboard amp. Guitar—through a keyboard amp? No, I am not crazy. If you’re like me, you are constantly adjusting your volume and tone when playing live. You need to know exactly what effect your tone tweaks are having as they go direct to the PA system. Consider that if you play your modeling product through a regular guitar amp and speakers, that amp, and especially the speakers, are coloring the sound a lot.
A typical situation where this becomes an issue is with chunky muted rhythm sounds. You probably spent some time at home dialing in a great preset on your modeling product that sounded awesome. Then you get in a live setting and play that sound through a guitar amp. The speakers in a guitar amp typically don’t have a lot of bass or high frequency response, so in order to rock it all the way to the back row, you crank the low end on your amp to get your sound. The problem is that you were already getting your sound and sending it to the sound tech, and now your onstage amp sound is nothing like what you are sending to the PA. It would be much better to monitor your rig through an amp that sounds more like the PA system, such as a keyboard amp.
In big-time situations, you could even just monitor your guitar sound through your PA system floor monitors or in-ear monitors. Many touring pros are doing that these days. The point is that it’s critical to have your onstage sound and the sound through the PA system match.
There are some who have taken a different approach that is also valid. They like the idea of a modeling amp and effects but still want to play it through a traditional amp to warm up the sound. This can work great, but it is probably a good idea to mic that amp and send that signal to the PA rather than taking the signal directly from your modeling product.
