This Big Mud is based on several of my Russian style Big Muds like the Red Mud and the Civil War and is my version of the late green, early black Russian BM circuit in the big box with the bubble font artwork. It uses NOS KT3102 transistors just like the originals and my Red Army ODs. I have added a push/pull pot to the TONE control for more mids while keeping the tone control intact. It's not flat mids like other Muds I make.

It has a big bottom end similar to my Civil War but clearer and tighter with less flab than the Red Mud. This Big Box version is my custom made stainless steel enclosures about the size of the Black Russian BM. This Bubble Mud is only available in my "big box" series.
