Maxon ST-01 Super Tube Screamer. This is the Maxon overdrive “ST-01 Super Tube Screamer” that I used to use. It has been stored without being used for a long time, but I was able to confirm that it is powered on and working. More than a regular Tube Screamer, It is characterized by the ability to fine-tune the sound with settings such as “MID BOOST, ” “SOFT/HARD, ” and FAT/TIGHT. It can handle sounds ranging from warm crunch to heavily distorted sounds. The exterior has signs of use and small scratches, but I think it is in pretty good condition considering its age. The back cover is missing (as shown in the photo). I only used the last one with the adapter, I used a thin board taped to the back cover. Sometimes the foot switch doesn’t respond right away. It will respond if you press it lightly again, so please understand this. Only the main unit is listed. If you have an understanding of old effects pedals, please come along.
