I read an article this morning from Guitar World on MSN.
They provided some compelling information arguments stating five reasons why someone should switch (citing touring artists switched, so why not you?)
"While sound quality was once something that held modelers back, it is now a big reason to buy": Five reasons you’re better off with an amp modeler than a tube amp
Portable
Reliable
Price
Flexibility
Sound Great
Can't get myself to do it. to me I find modelers to be finicky, prone to fail, and won't last in the long run.
Tube amps are heavy, so digital modelers win there. I started using a separate head/cabinet. But really, I use a cart to move stuff around. Hardest lift is in/out of the truck. None of it is that heavy, its not like I'm lifting a 100w 2x12 Fender Twin.
Reliability is subjective, digital modelers are great now, until the software becomes outdated, until fails, and there is no way to fix it. Digital modelers are disposable items that do not retain value in the long run.
Price is also subjective. To achieve the high-end tube-like sound, you are paying way more than most tube amps. Sure, there are cheaper alternatives, but they aren't as good. Plus you still have to get a monitor system, my band asked me to look into going direct. I asked if they are buying me a monitor system so I can hear my guitar? Going to front of house doesn't help me, if I can't hear anything beyond the vocalists monitor.
Flexibility. The right tube amp in combination with the right pedals, you can achieve nearly anything sound you want. Even rolling back the volume on your guitar to clean up the sound makes a huge difference.
Sounds great. Tube amps sound great, modelers can, but you buy a modeler, then have to spend more on a monitor system for it.
There are pros to modeling of which I won't deny, but I have yet to feel (yes, feel) a modeling amp that feels like a fire breathing tube amp. There is something about the sound and the feel when you have a 50w/100w head pushing a 2x12 or a 4x12 cabinet.
