ES 137 has
mahogany center block - not maple. Chromyte - also called Balsa - is not cheap wood. It's actually quite expensive and light and soft - and that's the reason why the 135 has no sustain and bottom compared to a 335 - so still, Emmitt, 135 and 335 are very different guitars both when it comes to construction details and when it comes to sound. To my humble opinion they cannot be compared at all. And BTW today the sky is blue...
