I play guitar, and just started bass recently, and I usually just record DI into the soundcard and then use amp sim softwares like Guitar Rig, Amplitube..etc. I do have a small practice amp (Crate GFX-15) that I use for the guitar, but it cannot handle the low-end of a bass at all. I'm looking to get a practice amp for the bass (Warwick Corvette $$ 5 string), and I'm wondering if it should be a decent amp that can be used for both the guitar and the bass, or one just for the bass. I don't even know if there's such a thing as an amp that can handle both guitar and bass? My main reason for using amps at all for practicing is so I don't risk blowing out my $7,000 studio monitors (I'd kill myself if I did that). for recording I just go DI like I mentioned.
