I'd day everyone needs one of these in their collection for a little something special.<br /><br />It REALLY shines with a nice low output humbucker. I just recently plugged my Gretsch Double Jet into it and lordy it sounds nice.<br /><br />Plus it looks fuckin sexy with a tube lit from the bottom. Never under estimate the power of "sexy."<br /><br />I need to play around with getting the led to pulse with the tempo so it'll look like the tube is flashing in time.
