I used to think I'd need a half-stack at least to sound decent, and always had minor issues with my Flextone II being too bassy when cranked louder than bedroom volume (yes, I had some complaints with it, hense why I really really wanted a Vetta or something newer to see if they were any better), but I got bored today and decided to try and emulate a sound I really love: Three Days Grace's live tone. It's simple enough, on the surface. Loud, aggressive rock tone, yes? No. They have a great sound because they have the guitars running with less bass than I would have expected, and work with the bassist's sound (much louder than most other bands, and a good thing IMHO) to create that heavy tone. The guitars' sound isn't very heavy on its own, but as a band they're brutal
So I began experimenting with the bass setting on my Flextone II, and came up with a decent tone, but it didn't quite sound right...until I turned my amp's master volume up slightly (from just below 3, to right on 3, BIG difference in volume), or a lot (up to 5 in my experimentation), and that's when it just came alive. I fell in love with this tone I was getting, it was perfect
With my Squier Strat, or my Schecter 7-string, it was great
So now I have a new live sound, I just need to find a way to get this amp to sound like that at lower volumes
But at least I now know I don't need a huge amp to have huge tone.
