PLX Bion Boost

My favorite boost pedal. PLX Bion boost. It's a treble booster based on the Rangemaster treble booster.
Same Drop B guitar with a PAFish pickup. Peavey Sheffield 1200 5150 speaker mic'd with a SM57 into my UA Volt 1 and straight from there into my iPhone.

It's a Peavey VTM.

What amp are you boosting with this? Sounds great!
