I've had a handful of opportunities to play the phenomenal Marshall JVM410 head/cab set up. With four channels and three modes per channel, it does a lot of things really well. My question comes in, and this is just to start a general conversation because I like seeing how people think, would you keep the stock Celestion G12T-75's, or do a very popular swap, and put in four G12K-100's. I've read that this particular speaker gives the a lot more depth and low end to any amp it's hooked up to. What would you do? I personally would do the swap, because I'm a "bigger is better" kind of guy, good thing or not, plus I'm not known to leave well enough alone. Discuss.
