Product Details

Bravo Audio Tube Guitar Boost Effect and Overdrive

The Booster is a device that connects between your pickup-equipped stringed instrument and either directly to your output stage amplifier, to the next effects processor, or to another amplifier (not a headphone amplifier) that will further process the input signal. Its sole method of amplification is via a single Shuguang 12AU7 vacuum tube--that's it. The simple and elegant design uses only three knobs: one for volume, one for gain, and one for tone.

One really nice thing about the Bravo Audio Tube Booster is its flexiblility in usage. Combining different levels on two of the knobs can result in a variety of effects. 50% volume and minimum gain gives you the classic, clean, rounded tube sound most of us "HeadPhile" enthusiasts all know and love. Maximum volume and minimum gain results in a volume boost to prepare the signal for further amplification or for feeding into a distortion or multi-effects device. 50% volume and maximum gain give you a nice, moderately face-melting, distorted, overdrive sound. Maximum volume and gain combine the two previously-mentioned effects.

Includes universal / international 12 VDC switching power supply and power cable. 1/4" (6.35mm) mono input and output jacks.

Can I

Can I have this between my guitar and Amp/speaker combo? The amp is an epiphone all in one amp slash speaker box.
Asked by: firemanstep
Yes you can. You can have your guitar volume at 1/2 to 3/4 for clean sound then punch it to full for that nasty tube overload distortion that gets attention. Great for sustain as well.

Which jack (J2 or J3) is the input for the Bravo Audio tube guitar booster (#310-358)? Neither jack is labeled.?

Also, this item is listed as having a 24VDC power supply. It does NOT. The power supply is only 12VDC.
Asked by: Stephen6760
Found the answer. Jack J2 is the input.
