Tascam Model 12, Zoom live track, or Bluebox may do the trick. I don’t own any of them but looking myself atm.
Though @natehorn makes a great point. What are you planning on doing with the recorded tracks? I am looking at the above gear to multitrack and overdub with live instruments. Use them as a songwriting tool. Knowing I’ll have to use a PC eventually.
As a full time IT guy I relate with the OP. I only get a small window for my hobby. It may be more work but the last thing I want is a PC during the jamming/writing process.
