Hello TB, I have been testing this Sansamp programmable DI. The rig I tried to was an 8x10 ampeg and a GK solid state head I forgot the model. The bass is a P bass fender. I tried playing with the knobs a little bit and with the little manual I found on their website. During a couple of practices I figured the EQ on the amp has to be all off, cause I hear I weird loud hum If I dial in the EQ from the amp. I also read the manual about not using the amp EQ. But I see that the sound is very muddy. I think I am dialing the pedal to sound like an SVT amp. Do you know some dialing so it sounds less muddy? I mean lately I had to just turn the pedal off and use the amp's EQ, cause it's just too muddy.
For the purpose of discussion lets assume your sansamp setting are preclose to this illustration: http://www.tech21nyc.com/support/manuals/sansamp/BassDriver-OM2.pdf On the GK is the EQ flat or are you rolling all the knobs to the left as far as they go? (Never had a GK amp so I'm not sure how the EQ is setup on them)
