Did the dc brick work well for you fivestringgecko? I'd been warned off them, because apparently they don't have isolated power supplies. If so, then the MXR M237 DC Brick would be ideal for me, great size to fit under the pedaltrain mini. Out of curiosity, what do you run the b7k on - 9v, 12v or more? The 18v pedal on my board will be the diamond bass comp, just wondering if the b7k needs extra headroom?
