Slightly unsatisfied by my SD-1, I was off to Guitar Center this weekend. I decided to pit the SD-1 against a Soul Food, and just for fun since it was also on sale, the legendary Tube Screamer. They also had a BD-2. As I suspected, the SD-1 just did not have enough of a boost. Was pleasantly surprised by the BD-2, but found it a little bassy, and was worried it would be useless to boost a gain channel. Also as expected, the Soul Food was totally transparent. Ultimately I went for the Tube Screamer. It brought the mids I was missing. Putting it in front of the DC-5 on the regular scooped EQ settings, it pulled everything together.
