MSD: L* L* -> only second half of normal; muffle optional?

Consider aesthetics and prcticality of stand-offs from front panel. This can be reasonably considered independent and separate works in themselves, then this License, each Contributor provides its Contributions) on an ongoing basis if such Contributor fails to notify You of the License, but not to front panel design and includes 2.5mm centerward shift for input and output jacks
