I'm relatively new to the technological side of music. My guitar amp has a speaker cable output, as does my keyboard. I would like to be able to plug both of those, and also a microphone into a device which I can plug headphones into and listen while I play and sing. I'm trying to keep quiet because of apartment neighbors.
What kind of device would allow me to do this? I did some googling and searching here and I saw a lot of recommendations for JamHub, but it seems that company has gone under. A lot of those recommendations were for devices with multiple outputs...I only need one headphone output for myself to listen to. Any help would be appreciated, I have no idea where to start.
I looked on Amazon, is something like this what I'm looking for? https://www.amazon.com/dp/B004TM31QK/ref=psdc_11974881_t3_B07QDN6Z83
