This started out life as a brand new Swamp Thang tremolo pedal, made by Monster Effects. In my humble opinion, these are the very best sounding vintage tremolo pedals you can buy. If you did that old brown-face Fender Tremolux sound, this is your pedal. These are $199 new. I got this, then got an amp with built-in tremolo, so never used it. I decided to customize it awhile back and did this fancy paint job and customizing. It’s now the Vibrosonic FEZ pedal. It’s the only one like it in the world and it can be yours! This price includes shipping! Yeehaw!!
