Check out the new Cream 2005 DVD! Jack Bruce playing a gibson EB-1 through 2 hartke 8x10 stacks (each w/ a 5500?) and 2 1x15 (maybe 18?) gets a fantastic tone! I realize Jack can play anything he wants, and at his level may have an endorsement from Hartke, but I was surprised to see Hartke, and was surprised by the tone! I also thought his EB-1 sounded better than his signature warwick fretless! Even though I'm an old timer and am familiar w/ Cream's hits, i've never owned a cream album, but while watching the dvd it struck me that I play in a style similar to Jack too!
