Monsterbox Pedals The Jack Shack Preamp 2026 - Silver

The last massage parlor in town was forced to shut down. Apparently Rub and Tugs are prostitution too! Now my friend Larry has nothing to do 3 or 4 times a week so I made a pedal about it. This old school Preamp is a modified take on pedals like the Dod 250, Distortion Plus, and Ross Distortion. It does everything from Boost to Distortion and all the things in between. The revolutionary Jack It footswitch lets the user toggle between two sets of controls. It also changes the led color when hit allowing for a Blue light or Red light setting. This is the worlds first pedal to encourage players to Jack It and offers two ways to do it. 

Power Jacking - With the pedal On - This is the most audibly satisfying way to Jack It. I like to have a nice boost set on blue side and max out the Goo on the red side to blow out loads of distortion. Power jacking is also what Larry has been doing in his tool shed. 

Off Jacking - Jack It with the pedal Off. If its on red when I turn it off and I want it on blue when turned on next... All I have to do is Jack It real quick and it's good to go.

The 3 way clipping switch has symmetrical, asymmetrical, and a diode lift in the middle
