Any chance you can post some soundclips when you get it tuned down to the low E?
I've been debating if I should sell some gear and buy a Dingwall to go an octave lower, though I haven't really heard anybody play one that low outside of a mix context.
I pray to the bass gods that they'll force Dingwall to make a lefty of this. A six string version of this is pretty much my dream bass. HNBD! It looks awesome.
