So the world of bass guitar amplification is still fairly young. I think the current (2015) tech in the bass amp world is pretty advanced (especially even compared to just 20 years ago) but I was wondering which current trends are game changers and which will just be a flash in the pan? Now, not talking about "stepping stones" that will be replaced with a more developed version of the current tech - but true fads that we can look back and say "remember when everyone was using _____ and ditching their old gear?" Considering that many players are still using the same bass as was created in the 1950's, amp tech certainly has a lot more fluctuation! Note: this thread is purely speculation. We can look back on it in 20 years and see who was right though. Here's some starters for possible fads: -mixed drivers in single cab -class D amps -neo magnets -super high wattage amps or cabs Ok, go!
