EDIT:
You can match the EQ pretty close to the original Direct Input Instrument with a bit of EQ work or use something like Voxengo Curve EQ: Pic 1
1. Click Edit - Set to AVG
2. Put a sample of the di guitar on the track with CurveEQ, play it, when the curves level out click "Take" in the Static window.
3. Put a some samples of your instrument you want to match to the RealTrack on the same track, play it and hit the next "Take" down.
4. Set the first take as the Reference.
5. Set the next take as Apply To.
6. Click "Match Spectrums".
7. Select All the wav samples of the sfz or the extracted wavs from the gig instrument and drag into the same track in Reaper or your DAW.
8. Select All the wavs in the track > Render "Selected Items, Wildcards > $item, backup the original wavs and replace them with the new EQ Matched wavs, this will give your instrument a very close sound to the Direct Input RealTracks that will have the FX added later.
