Once you select your capture and place it on the signal grid, you can adjust the gain and EQ (with varying results). Usually you would use a gain block prior to your capture to bump the levels if needed but it depends on how you are configuring your preset and have I/O configured. Essentially, you don’t want to modify a capture block gain or EQ as it will change the overall tone of your amp/drive capture but it’s easy to do and you may like the results.
Agreed, I would start there and see if you are satisfied with the results. Assuming by your screenshot that you are using line out from your amp etc., some have used a DI box for better results but it certainly isn’t required. Hopefully, someone will add to your thread better details for capturing your specific amp.
@xush is preaching the gospel with the above comment; the input level seems to always get raised to get a solid capture on the other side of the equals sign. Wish it was something mentioned to me when I first started with the QC
