T-Rex's Most Versatile Power Supply

The T-Rex Fuel Tank Chameleon pedalboard power supply has the ability to power most of today's popular pedals, no matter what their power rating. Onboard are five fully isolated power outputs that can supply 300mA each. And a set of dip switches allow you to run pedals that require 9, 12, and 18 volts DC. You can even use the Chameleon to power 12-volt AC pedals. And it is switchable to be able to accept 115 volts or 230 volts for traveling abroad. The T-Rex Fuel Tank Chameleon power supply will power just about any type of pedal on the market today.

T-Rex effects: guitarist designed, quality built

Danish tone pioneers T-Rex Engineering have been making quality effects pedals and guitar gear since the 1990s. T-Rex pedals are made using some of the best components in the industry, like film/foil electrolytic capacitors, lifetime-use pots, and rugged footswitches, toggles, and connectors. T-Rex's better-known pedals include the Replica digital delay and Mudhoney distortion, which can be found on the pedalboards of top guitarists David Gilmour, John Mayer, Mark Tremonti, and Steve Morse, as well as many of Sweetwater's players.

What is Demo Gear?

At Sweetwater, we're so picky that what we call a "demo" is actually better than what most music retailers sell as "new" gear! Our gear hasn't endured hundreds of people a week plunking away at all the keyboards, fumbling through Stairway to Heaven on every guitar or playing with every fader and knob on a mixer or control surface.

What demo means to us is that we've had it out of the box, or maybe it was in a customer's hands for a few days and isn't "factory fresh" as a result. Every demo item we sell has Sweetwater's 2-year Total Confidence Coverage™ warranty, and has been tested and verified up to "new" specs by our factory-authorized technicians to make sure it's in perfect working order before we ship it to you.

When you buy a Demo item at Sweetwater, you get:
  • 2-year Total Confidence Coverage Warranty™!
  • Products inspected and tested by our factory-authorized techs, guaranteed to function like new (or better)!
  • FREE shipping on most items
  • Equipment that will MEET or EXCEED your expectations!

Rated 5/5

Sound floor

I have a pedal board with a couple of vintage (mid 70's) units and a few other 9 volt units. I used battery clips to replace all 9 volt batteries and daisy chained from a 9 volt source on the chameleon. So that's 5 9 volt units, 3 12 volt units and an 18 volt unit all powered by the chameleon. I never would have believed that my signal could be so robust and clean. After I plugged it all up, I was searching for a bad connection, but there wasn't one. I strummed the guitar and voila! Noise floor was nearly inaudible and the tone had much more bite. I was blown away. Not to mention all the space saved by removing the many power adapters used prior.

Does the job Well!

Perfect fit on my board and love the Blue LED on light. No humming at all and is my second board I’ve built.
Rated 4.5/5

As Advertised

I've had this power supply a couple months now & it gets the job done nicely. It easily accomadates the 5 - 7 pedals I use regularly & doesn't add any annoying electric buzz. Also, it fits neatly under my (Pedaltrain) pedalboard.
Music background: Guitar player 35+ years
