I will totally agree with you there!

At one point, I was pretty self-conscious about "going live" with my aged and obsolete Line6 X3 Live. I was intimidated by all the various internet forum (not TTR) declarations of "that amp model doesn't sound like the real thing" or whatever.
However, when joining this band, I had to go with what I had and being able to do a quick setup on some small stages pretty much made using my humble processor essential. I didn't have the time or money to get something more up-to-date. Well, I could have afforded something newer, but I'm not dipping into savings just for more guitar gear. I save up for that stuff.
What I have discovered, quite happily, is that it doesn't matter if some particular model sounds exactly like the real thing - whether it's an amp model, speaker model, effect model, or whatever. When people are jumping on the floor and smiling and singing along to the tunes you're playing, you realize that no one cares at all if the Twin Reverb model I'm using or if the Plexi model I'm using sounds just like the real thing in an A/B test. What matters is if I can create a sound that fits the song.
And, if the whole band is loud, all the better!
So far, my old, but rugged and reliable X3 hasn't let me down and it keeps cranking. Letting go of barely perceptible nuances has saved me a lot of money and time.
