I clicked on a Facebook ad the other day for a pedal company that advertised preamp and/or tone pedals with dual transformers that came out of the top of the pedal case - almost like tubes. It was interesting. I thought I bookmarked the page to look at it further, but forgot. Ugh. Now, after searching the interwebz high and low, I can't find it. Anyone know who makes these pedals, or what they are called?
