## Description

Bravo Audio has been making some waves with their line of Tube powered line headphone amps as well as the Tube powered guitar Booster SHOWN HERE (please see my other posts for other Bravo Audio offerings). Bravo Audio gives you the warmth of a tube in a unique little package. This unit is not voiced for distortion output or even very colored Overdrive tones, but rather adds a second layer of volume and boost to your signal. Can be placed in effects loop or in front of the amp to conjure up some nice tones and harmonics. Very cool little box ! Just to be clear on this unit and to ensure you are aware, please note the following: What it is: a very cool little unit that provides tube driven power and boost to your amp/ signal chain either in effects loop or as a pre-amp to effects chain or direct from amp-to Booster- to guitar. Supplied with it's own Power Adapter and ready to go right out of the box. What is it is not: This unit is not True Bypass and therefore if you turn off power to this unit, any other effects that are chained after this unit will not remain powered. Also this unit is not designed to placed directly on a pedal board where damage could occur to the Tube and other components. Specifications: -6.35mm Mono input, 6.35mm Mono ouput. -Tone control knob -Gain control knob -Volume knob -Shuguang 12AU7 tube

Review: Bravo Tube Booster - This little product is incredible, I did not want to take out any of my big amplifiers so I connected this little beautiful tube booster to an orange micro crush 3 watt 4 inch speaker (9 volt battery). The results were amazing, no one believed that the sound was coming out of that small amp. If this Bravo sounded this good with a battery operated amp, can't wait to hook it up to my Vox ad50vt. This is a case in which the manufacturer was right on. Do not let the delicate look fool you this is one well made piece of high tech equipment.
Review: it caused noticeable distortion and not the good kind. The gain could be more linear but ... - I've had this preamp now for about 3 weeks. I've replaced the power supply, it caused noticeable distortion and not the good kind. The gain could be more linear but otherwise I'm very pleased with it. Along with the bravo headphone amp v3 next to it on my coffee table makes a perfect apartment practice setup. Reminds me of a mini dumble. I definitely plan on buying more.

## Questions & Answers

**Q: I own a line 6 spider IV and I want to warm up the sound. Would this product be right for me?**
A: Josef,I use this Booster with a 100 Watt Solid State Fender amp and I find it warms up the sound and makes the overall tonal response a little more buttery and not as harsh. Sound is always subjective but this is what I have found on the unit.

### ⭐⭐⭐⭐ Nice for warm tones
*by S***N on April 8, 2015*

Nice for warm tones. I have experimented many tubes in this device (AX, AT, AY, AU and AV,s). All contribute a noticeable difference in tones especially using older GE's and Sylvanias. A good overdrive tool!
