Not really. I suspect that we could do better, but in many cases the volume depends on the input source.

For this reason, each preset has an output level settiing.

Right, I suspect that for many users, they are just using one input source. Having a master output level in the options (with the option to enable/disable) would be useful… if fact, it would be useful if you had more than one input source, because it would enable you to compensate… if I’m using a high output bass, I could set it one way, then if I have a passive guitar, I could set it another way.
