Hi There, I'm trying to make a decision on getting the Ampeg PF800 or the Sansamp RBI/RPM combination. I own a Hartke LH1000 but not thrilled with the tone. Would the Sansamp preamp combo be able to cop the same tone as the Ampeg? I used to have a defective PF500. When it worked the tone was awesome. But I feel like if I got the PF800 I might be missing out on some good Sansamp tones. What do you guys think?
