You can't plug an electric guitar or bass directly to your soundcard unless your soundcard has a high impedance (sometimes referred to as hi-z) input. If your sondcard doesn't explicitly say it has one, you need something to convert the impedance of the signal. For this, you need either a suitable DI (direct input) box, or (more preferably) an external preamp with a hi-z input. > OTOH, I thought jack-rack could be my friend.

This is mostly my fault as i've never really undrestood it. OTOH, jack-rack is wonderful as you can use all available ladspa plugins. The DI bass i have tracked, has benefited a lot from the use of a compressor. The idea is to use the compressor to lower the volume on the start of the notes (the louder ones) and the "makeup gain" to get the whole signal hotter. Other stuff you could use are the "Tube amp emulation" and "Tube preamp emulation" (with or without tone controls). With enough drive, you won't need a separate compressor as the emulated amplifier drive will work like a compressor when driven far enough. That will result in distortion though, but the idea of amp distortion is to sound good. :) That's the basics as far as i know. Next lesson is to experiment with EQ, chorus, phasers, harmonics, delays. Good stuff can be achieved with all of these, depending on your preferences and the music you are doing (both in general, and the specifi piece). Good luck! -- Sampo Savolainen <v2@xxxxxx>
