Hi guys, This is my first post on this forum. I've pulled lots of info from here so i want to thank you all in advance for that. However this time i'm looking for some info/advice that i haven't found here or anywhere else and i really hope you guys can help me out. I play in a post-metal band and we play quite loud during practice. I currently own a Ampeg PF410HLF and i use a borrowed Ampeg PF800 head. I'm at the stage that i'm going to buy my own amp and i'm at kind of a crossroads. The current PF800/PF410HLF combo comes a bit short on the loudness during practice and i also feel that i'm missing out on the lower frequencies when playing on louder volumes. As far as i can tell from the forums, the PF410HLF is well known for it's lows, and i feel like i'm missing that currently with the currently paired/borrowed PF800. After lots of reading i have come to multiple options on how to solve this and i would be incredibly grateful if you guys could give me some suggestions. As far as i see it, I can buy my own PF800 and extend my PF410HLF cab with an additional PF115LF (i've read posts for and against this solution. Mostly against as the PF115LF has a different power rating which could cause problems, or that it would not add much to the 410 as it's supposed to be a stand-alone cab. I'd love some confirmation on this.) Buy a PF500 instead of a PF800 as i've read topics that imply that the PF500 would be a more suitable amp for a single PF410HLF and would improve the sound and tone of the one i already own. I have read on the TB forums somewhere that with the PF800, the PF410 can fart out on higher volumes. Again, i would love some confirmation on this. Sell my PF410HLF, buy the PF800 and add a PF210HE and a PF115LF. But with that, i would sacrifice the portability of the PF500 or 800/PF410HLF combo. This would be a downside as i am in a (sometimes) touring band, so portability is quite a big plus. I'm at a total loss as what the most logical way to go would be, so i really hope that someone can help me out with this. Thanks so much in advance!
