I'm looking to streamline my practicing & recording setup to allow me to easily record ideas when I'm noodling around. I've had the idea to get a signal splitter that sends a signal to my amp and/or to an audio interface input so I can leave gear set up and quickly record my ideas. I've started looking into A/B and A/B/Y boxes but there seems to be a lot of options at many different price points and a lot of disagreement about whether or not the boxes affect the tone of the guitar signal. I think ideally I'd like to have an A/B/Y box as that way I could still hear the signal through my guitar amp when I record the dry signal. My reasoning behind this so that I can hit record and continue to play the riff/progression/whatever with the same feel since I'll be hearing it with the same tone and gain levels that I'm already using. I find that I sometimes struggle to play stuff with the same feel when its a dry signal, and I'd like to avoid wasting practice time by fiddling around with amp sims. The main concerns I have seen with A/B/Y boxes is that they change the tone and/or roll off top end. I don't think I need to worry about ground loops (or do I?) since I'm not using two amps. So I guess my question is, who can recommend a good ABY box that doesn't affect tone, and how much do they roughly go for? It seems that a good A/B/Y box costs in excess of $150 or $200, is that correct? I'm also open to the 'tripler' type boxes with a 1 input/3 output setup if these are any better. Can the inherent problems of an ABY box be solved by a simple passive A/B box? This is obviously a much cheaper solution but I would lose the convenience of hearing both signals at the same time. Are there any cheap A/B boxes that will do the trick in a pinch? Are there any other suggestions outside of AB or ABY boxes that might help me achieve my goal better?
