Hey DSS3,
When using the Palmer are you going in straight from the speaker output of the 5150? I'm curious, do you have the attenuator set to 30db? Are you using the lead channel on the 5150 boosted?
What impulses are you using now?
5150 speaker out-> Palmer -> loadbox. I think I was using the 15db attenuator. Lead channel on the 5150, OD808 infront.
Impulses were FRED45-1 and my Mesa 4x12 SM57 pres 8 (2 of each) on the first, and all Sneap Edge on the second.
