I see amps have effects out and in. I take it this is after the EQ and stuff? So if I had another preamp that I wanted to try and didn't want to go through the hasle of rewiring, could I put the preamp to the effects in and run the bass into that preamp? Why I'd want to do this? Let's say I have a commercial preamp but I decided I wanted to build a DIY preamp. I just wnat to try it to see if I like it? YEah, it'd probably be better to rewire anything. I'm just wondering though.
