wow, how many have you chained together at once? That would be a wall of sound if you ran 2 0r 3 in front of the amp and 2 or 3 in the loop. Crazy, that is a great collection.
I just noticed they are all set pretty close.
They're not chained together, it's just a photo of his collection.
I've got a V5 op-amp Big Muff, absolutely love it, massive sound. Had an NYC reissue before it which was okay but nowhere near as loud or punchy. The V5 with volume at 10 o'clock matched the reissue with volume set to 3 o'clock.
