So, I am in a band that has a banjo player, he has an acoustic banjo and an electric banjo. He was running both into this all in one Boss effects pedal that was robbing his tone. So.......that had to be deal with. http://www.d-tar.com/solstice.shtml Anyways, we were looking at getting a Dtar Solstice for him, and running each into the different channels. Well, before we ordered it, we tried using my epifani 502 for this guy, running one into each channel. Well, during this time, the channel switching function ended up being very useful, and I am thinking the Dtar Solstice, without that, might end up causing some issues without being able to mute the other channel. (yes you can turn down the levels on the one not being uses, but that would cause more issues than not) So basically this guy needs a two channel preamp that is switchable. The tone with both of them using the Epifani rocked, but I am not trying to give up the Epifani for this use in the long run. Band is willing to foot the bill for something like this, and this guy needs it ONLY for running direct out straight into the board. You guys not of a good two channel amp/preamp that don't color the tone all that much?
