I have tested connecting the guitar directly to the 003 as well as the pre-amp, and there is no difference in the tone quality or cable grounding issues. I have the Digi 003, and a Tascam 8/8 pre-amp. I am using Windows 10, on a 4 core 3.4 Ghz pentium and 16 GB memory.

But maybe this is wrong, and there is actually signal conditioning happening in the 003 that is poor?

My assumption is that the tone quality is not a primarily a function of the input signal from the 003, and is more an issue of the plugin software or CPU speed to do the signal processing.

The constant through all this investment has been Pro Tools, and the 003 rack. But I have a quality guitar, professionally set up, a Furman regulating power supply that all the equipment gets power from, and quality cables.

I realize there are many factors, including the guitar, cable quality, power quality, etc. And if it will, what setup (hardware/software) are guitarists using to get a professional sounding rig emulation? My question is whether upgrading the audio interface will help me solve the tone quality issues or hum problems. Along with the tone weakness, this setup has a lot of problem with hum generated from poor cable ground, in spite of my efforts to follow the normal corrections for this problem. Since PT 2020 does not officially support the Digi 003, I am considering upgrading my audio interface to a more modern one. My 003 is 20 years old now, and rarely used because I have never been happy with what it can do, going back to PT 8. Trying to reproduce tones of the major guitarists like Gilmour, Satriani, Van Halen, Carleton, etc seems like a impossibility with this rig. There is no effect that produces decent sustain in the high notes, and most of the effects are heavy distortion and modulations that are boring. I am very disillusioned with the quality of the guitar effects this produces.

I am using Pro Tools 2020 with Native Instruments plugins, mostly Guitar Rig 6.
