Hi Ben, welcome to the forums
The tone and volume can be affected if the action has been lowered "too" much. Taking the guitar to a reliable guitar tech is always a good idea but there is a way you could check this without new saddles.
I could send you some very thin rosewood shims that you could slide under the saddles to raise the action ever so slightly to see if that helps.
If you want to try this please send me a PM or e-mail with your full postal address email@example.com
cheers and thank you for choosing one of our guitars
