So I finally bit the bullet and got myself a nonpowered kemper from Sweetwater. Right now I'm in the early stages of the 30 day return policy. So far I'm finding it pretty awesome, just a few questions:
-Is there an agreed upon safe volume level for headphone output? I have a pair of sennheiser hd280s and have read some scary stuff about prolonged headphone use causing hearing damage.
-Is there an easy way to add some low end thump or kick for lack of a better term to some of the high gain metal profiles? I understand that when isolated from a mix, guitar tracks don't really have a big low end to them, but im playing solo in my basement so I find myself missing that low end compared to my 6505mh with a 1x12 cab. Is that just the nature of playing through studio monitors? I have a pair of jbl Lsr305s that I'm using, I don't expect Earth shaking bass or anything out of them but it feels like the low end is missing on a lot of profiles?
-I tried hooking up to the return of the fx loop on the 6505 and liked the tone, but I did find that I had to turn off the cab on the profiles for most of them. If I was to get an active PA speaker, would I still be turning off the cab or at that point do you just run the profile as is through one of those? Does it make a huge difference compared to running it how I am now? Would the sound be similar to the studio monitors and just louder, or would it automatically add that missing thump that I was asking about above?
Basically I have three ways that I play guitar, either through headphones because the wife and baby are upstairs or for playing along with backing tracks, through studio monitors for when I can get a little louder or just get tired of headphones, and through the 6505 mh turned down when everyone's asleep or out. The Kemper has blown away my other options for headphones and has at least matched my 6505mh head for use through the 1x12 cab. So now I'm just looking for tips on the above before moving on to phase 2 which is figuring out what gear to sell to pay off the Kemper and keep it.
Thanks for any and all help!
