I'm looking around at different 1u half-rack pres, and several mic preamps came up. Here's one in particular, the Alto Alpha MicTube 2-channel pre: http://www.musiciansfriend.com/product/Alto-Alpha-MICtube-2Channel-Preamp?sku=180330&src=3WDTWXX Tube pre with Hi-Z inputs for instrument signals, 2 channels, very low price, etc. Has anyone used any mic pres for bass usage? I haven't, and was curious if there's anything different in the response or handling. It (or something similar like the PreSonus stuff) would be a very useful addition for me. Any suggestions? Just seeing if there was something along the lines of the Summit Audio TD-100 but less expensive and designed more as a pre than a DI, which I don't need.
