GC only had the 18v for the egdm...WOW...I didnt think i could enjoy this pedal anymore...finally my high gain tones are satisfied...cant wait to try a 15v adapter on the HB...i think i may have to order one online...that means i have to wait...OH THE HUMANITY!!!
edit:
before leaving my rehearsal space i remembered i had this huge adapter from radioshack that had switchable voltages. the highest voltage was 12v! plugged it in, and man the HB sounded better for my taste. it sounded a little more open which i was lookin for. still nice and gritty, but just a tad more "open". i really enjoy the open-ness on my tim, but liked the overall tone of the HB. now i have the best of both worlds! im gonna use the TIM as my boost for leads.
