Santa Rocks

By Jody

from Warner Robins, GA

Santa brought the T-Rex Jr. Zip tied it to the bottom side of my holeyboard (amp top) and you don't even know its there. Clean wiring installation. Only one plug to deal with and no batteries. All of a sudden there is no noise or hum. Must be from all the individual grounds. The old Hot Rod Deluxe never sounded better.

Nice Little Package!


from Florida

This is a cost-effective alternative to the Voodoo PP2+. Recommended by a friend, it fits nicely into the top tray of my pedal Train Mini and I power five pedals individually. I am convinced that my pedals are, in fact, working "better" as their respective performances seem to be a little sharper and most definitely offering little or no hum at all. Suggestion to T-Rex: It would be nice if the five plugs would "click" into place in the power input at the pedal rather than just plug in and kind of sit there where they can come loose...

Small, light, easy, and quiet! The way I like it!

By Brian Lebo

from St. Louis, MO

This is a great unit for the money. Powers 5 9V pedal, or you can use to outputs to power an 18V pedal. Comes with all the necessary cords/plugs you will need. The Fuel Tank is amazingly small and light, smaller than some pedals. Just plug in and play and you're ready to go. I have had zero noise, zero issues with this unit. All my pedals work flawlessly (Crybaby Wah, MXR Black Label Chorus, Akai Flanger, TC Electronics Flashback, Dr. Scientist Reverberator). This thing is quiet, even in my noisy music room. IMHO, you cannot go wrong with this unit. Quiet, small, and portable. Even looks cool!

Gets the job done, nicely.

By Charlie G.

from PCB , FL

Great power supply for the price, I recommend it. Its actually quite small about 3x5 in. its super quiet and powers everything perfectly! It comes with a chain power supply also, so you can actually power ten pedals, quietly and effectively. Which if you think about it makes this an absolute bargain. Buy this one.

Works Great!

By Matt

from Shakopee, MN

The Fuel Tank Jr works great and is a cheaper alternative to the Voodoo Labs Pedalpower or BBE Supa Charger, but works just as well. No noise or hum! I'm powering 7 pedals with no problems. This is much better than the noisy 1 Spot that I tried. Isolated 9V outputs are the key to preventing ground loops and other noise. I wish the Fuel Tank Jr came with 3.5mm mini plug adaptors to power some EHX type pedals. And I wish the power cord was a little longer. Actually I give it 4.5 stars, but I'm rounding up to 5.
