I played a similar instrument in London last year, but it was fully (?) hollow and was as deep as an ES-175. It had one Bisonic and one Guild humbucker. It had a push-switch that cut either all the highs or all the lows from the Bisonic, but the bridge humbucker was where it was at! Quite a strong, spanky attack and little sustain. In the higher register it sounded like a banjo.
