Demonstration of DIY effect named the Thunderchief. The gain is maintained at 12:00 and clip starts with tone knob rolled off and gradually increases to max volume with the last passage boosted with an MI Audio Blue Boy Deluxe.
Marshall Super Lead 100 pedal through a Peavey Classic 30. Guitar is an Agile 2800DLX with High Order Alnicos. See www.runoffgroove.com or www.generalguitargadgets.com from more pedal info. This is my favorite DIY effect for a Marshall amp sound with humbuckers.
