I´ll keep my Avalon 737 & the SPL Channel One vor vocals,acoustic guitars,DI Bass,Sax etc..but I dont need the UA2610 anymore.I did a lot (well..all..)of guitar recording with it.For me it has the best "colour" for recording tube amps and since it is a two channel mic pre you can record any cabinet with two mics (like I did always with a SM57 and a R121/C414).It was one of my "main assets" when I had for nearly10 years my own studio in a big european country and recorded many bands and artists.
With the Kemper I wont use it anymore.I wont record whole bands anymore (dont have the rooms anymore to record drums and loud guitars) but right now have plans to go more into the songwriter/producer kind of thing.So it is all about Vocals,Kemper Profiler for guitars and drums,bass from pro tools/logic.
I also will soon sell my two Ramsa DA7 consoles.All good stuff but I cant use it anymore.
