Hi all... I’m a complete beginner when it comes to home recording. I use a Yamaha THX 10C into a USB port on my 10 year old laptop when I’m just messing around, but completely unhappy with the sound. I want to get a mic and record my tube amps. My laptop just died and needs to be replaced for the work I do... basically just word processing. But I would love to have the capability to run decent software for recording. What specs should I look for? Thank you!
