In recent years I’ve had the TC RH460, Aguilar TH500 and now with the Darkglass 900. The Aggie was a definite uplift on the TC, although the fan noise was a bit announcement . Now, I’m totally sold on the Darkglass. Great build quality and looks, lightweight, bundles of power and a great tone paired with my Vanderkley LNT210. I dial in just a little overdrive and it gives a great sound. Whilst all the video ad’s show the head being used for metal, I’m playing soul and funk and it gives me a great sound and exactly what I’ve been looking for.
