Are Amp Sims the Answer to Your Live Performance Dreams?

 

by Craig Anderton

 

Programs like Line 6 POD Farm, IK Multimedia's AmpliTube, Native Instruments Guitar Rig, and Waves G|T|R model a complete, computer-based guitar effects rack. As long as you're able to get audio in and out of your computer, you can create and edit your “rack” onscreen, with a degree of flexibility that's hard to do with conventional setups – but there are both pros and cons to taking the software path.

WAVES' GTR processor models both the amp and several different effects.

 

Pro: Owning the amount of gear that's virtualized in these programs, let alone creating a setup using that gear, would be insanely impractical.

Con: There's always a slight delay between the time you play a note and the time you hear it, owing to the computer and audio interface's latency (delay caused by processing time). Mitigating factor: Today's fast machines can deliver latencies below 10 milliseconds. This is about the same delay as moving ten feet further away from a speaker, and is virtually unnoticeable.

 

Pro: With a software-based system, there are no issues about getting individual effects devices to work together (impedance matching, levels, etc.).

Con: When playing live, toting around a desktop computer can be a drag, and a laptop usually has to be “babied.” Mitigating factor: Products like the Muse Receptor, are road-worthy plug-in hosts that are more convenient than desktop computers and more rugged than laptops.

 

Pro: The cost of a computer and suitable program is much less than buying the hardware needed to create an equivalent setup.

Con: You don't have the same kind of hands-on control associated with most hardware, unless you buy and set up a control surface.

 

Pro: For studio work, this type of program is a dream come true. No matter what sound the producer wants, you'll probably be able to provide it.

Con: Your audio interface has to work with guitar. Mitigating factor: Some software FX packages include an hardware interface optimized to work with both guitars and computers, and more audio interfaces include special inputs specifically for electric guitar and bass.

 

Pro: You can get a lot more sounds and flexibility than with traditional setups.

Con: Nothing has exactly the same sound and feel as a tube amp. Mitigating factor: When sitting in a mix, few people (if any) can tell that a modeled amp sound isn't the real thing.

 

Bottom line: For live use, you might still want to go with a hardware modeling box or conventional amplifier setup, although computer-based solutions are becoming increasingly attractive. But in the studio – assuming you like the sound and feel – the sky's the limit with this new breed of guitar-oriented programs.
