Well for the exact reason you first stated, I did start on headphones, then moved to practice amp, then today I pulled my typical gig rig and really demoed it out. I also saw on another post that I will link here that going out of send 1 or 2 instead of Outputs 1 or 2 will bypass the QC preamp. > [@Quad Cortex with Real Amp](https://unity.neuraldsp.com/t/quad-cortex-with-real-amp/6507): > > So, I got Mesa Rectifier Mini + Mesa 1x12 Cab for myself to have one real amp setup. I thought, that I’d use the Quad Cortex as a Pedalboard with this setup by using the 4 Cable Method. But so far I have been little disappointed with this. 1st Problem: When using 4 Cable Method I get some Dry Signal Bleed/phasing problem. I don’t know if it is a problem with Mesa FX Loop or Quad Cortex. But my tone clearly changes using 4 Cable Method. 2nd Problem: I also tried to use Quad Cortex in Front o… It for sure drastically altered the tone so I feel like that’s working and now I’ve built an entire preset from scratch (overwriting the old one before seeing your response so sorry I can’t provide that) and I do feel like I’m getting somewhere now. There is definitely still a coloration that is happening even on a blank slate preset that I’m not sure I’m in love with, but I just got the thing so I’m pretty sure with enough tweaking with EQ, compression etc I can get what I’m looking for. Not to dismiss my own post, I guess I’m still wondering if people find their bass tone kinda hollow sounding out of the box and need to do a lot of compensating or if there’s something I’m missing. Also checked another post and tried altering the impedence but I couldn’t really hear a major difference in respect to what I was concerned with about the tone. Any additional suggestions would be great though! --- _[View the full topic](https://unity.neuraldsp.com/t/using-quad-cortex-as-a-pedalboard-with-amp-on-bass/15091)._
