Garageband Latency issue

Description of Issue:

Until 2 weeks ago I was using my Squire Bullet Strat only connected to my Mac Studio M2 Max, using Apogee JAM. I am following the Garageband Guitar Lessions and the Accord Trainer.

Now I have bought a Mustang LT40S and it sounds great.

Here is my Problem: I when I connect the Mustang Amp to the Mac (USB-Micro, USB) and try to use the Accord Trainer, my Guitar sound from the Mac is delayed. So I turn down the Gain of the AMP, but play and sound does not Match. This is not really fun.

In the user docs I could not find any hint how to solve the issue.

Could anybody help me with this Problem?

Many regards
