Lr baggs tune o matic. lose sustain?

[HIghAndDry]

Who has used the LR baggs tune o matic bridge> How is acoustic sound and do you lose sustain compared the standard tune o matic. I am thinking of getting one for my 2012 LP standard. I am pretty accomplished on acoustic guitar and quite familiar with various acoustic pickups. I therefore don't expect it to have a sound that equals my K & K equipped Martin OM but am wondering if it has a reasonable usable acoustic type sound. And does it detract from sustain/ tone etc
