Hi, guys! I have to make a decision by the end of the day because of delivery time before a set of gigs that starts next weekend. The amp is Hartke Kilo. I have tried the Hartke HX410 Hydrive cab with it. I was pretty happy with the combination, but also not used to the "bright attack" in its sound. I am sure I will be happy with this combination. The other option is the Ampeg PF410HLF. It is available and can be delivered in time, but I can't try it today. It obviously has a deeper sound than the HX410 cab and will give me a different tone. So what is your opinion? Have you tried both cabs with this amp or a similar amp?
