Hi,

    I recently built a bloviator, both in protoboard and PCB. I used the schematic and single
sided layout from the site. In this layout, the IC3 (TL074) has its ground and +Vcc swapped.
When I fixed the problem, plugged a guitar, amp, 9v PSU, and only got a loud popping, like
a motorboat at speed. The same ocurred with my protoboard build. The chip (TL074) also got
way hotter than normal.

    Besides the mistake in the layout, I still can't get it to work. Any ideas?
