Having some cool effects at your disposal when playing your acoustic instrument can highlight your performance and playing, but the effects should not cover up the instrument´s acoustic properties/sound and should act as “enhancers” of what´s already there. With a good pickup system, what most players look for is subtle changes, because essentially, they want to hear the instrument, only louder.
More importantly, we need to be able to use the instrument in various environments that are quite hostile for an instrument that is designed to be played acoustically. If signal phase, impedance and feedback mean anything to you, you already know that amplifying acoustic instruments often involves patching in various electronic gadgets that you´d never use in your electric setup,

Ego Drive was designed to give you the overdrive edge that only the highest-end amps can produce – and then let you kick it into turbo with a unique boost function. Additional controls let you fine-tuneyour tone to create your own signature sound.

Ego boost n' drive

T-Rex Bass Juice offers organic distortion specially designed for bass.
In normal mode (boost function off) it delivers awesome sustain with rich creamy overtones and big bottom.
Engage the boost function and you are in fuzztone heaven!
The mix knob let's you blend just the right amount of distortion with your original clear tone.
Remember that Jamiroquai sound, where it sounds like the bass kicks the paper of the speakers. The Bass Juice can do that - and many other things.

Bass Juice

Booster is the perfect solution for making sure your solos and singlenote lines are loud enough – without having to sacrifice tone on your
rhythm parts or adjust your amp while you’re on stage.
With just a BOOST control and a subtle, tone-shaping SCOOP control,
Booster is one of the simplest pedals we make. But it’s one you find
yourself using constantly.

Tonebug Booster

The T-Rex Vulture started its life, when Michael plugged in one of the very first pedals we made. That pedal had a certain sound to it that we really liked, but it was a bit grungy in the low-end. We wanted to make a pedal with that sound, but with a tighter, less fuzzy low end and with more gain.
We opened up the pedal and painstakingly measured everything in it, to find out why it sounded so good, and found a couple of resistors that would be better with other values.
Was it modified earlier in life or was this just a very good sounding mistake from when it was made in Lars´ basement way back in the 90´s?
All we know is that the basic sound was cool and we left it at that, and went on to focus on getting the low-end tight - but BIG!
The fruit of our labor is a pedal that has a great, throaty distortion with a nice bite to it but the low end and low midrange can be shaped in many ways, thanks to the low- and fat-boost knobs. This allows the player to dial in almost stupid amounts of lows, but the distortion stays tight, not muddy.
