Hello. Are You fully satisfied with Your #1 bass or there could be some changes. If yes - what would You change ? As to me - Ibanez GWB 1005, i would like it would have a mid eq control also.
If you want only to hear your live bass and prerecorded drums on your pc through headphone - you don't need usb and good pc. Just buy a 4 chanell mixer, connect with your bass, stereo input from pc output and plug your headphones. You will get your sound eq and all this will be analog way.
There is a one important thing also when using usb interface for monitoring and recording and good latency. You will definetely need a good pc -ssd drive, 16GB ram and normal speed procesor.
Better to change for new ones, but there could always be some nuances with string height, so if You are not afraid to do some possible settings with Your bass, go for new. In recording and mixing fresh strings are important.
You deffently doesn't know latvian. What i ask is just a quality brand, meaning as a car to bass. You ask "Will i fyc( you?" Learn the languages pal, it it will easy your life.
I usually change strings after half a year, just the one and only D'addario 45-135. But if i feel sooner they are worn, i do it earlier. The recordings are serious stuff, so think seriasly to change for the new before rec.
