Q: What kind of cable do I need with the Bottle 'O Blues microphone?

A: The mic has a 1/4" jack on the bottom. Any good quality instrument (guitar) cable will work fine. I recommend a cable with a right angle end so that the cable exits the mic toward the floor.


Q: Is the Bottle 'O Blues microphone high impedance or low impedance?

A: The microphone is high impedance. It will plug into any high impedance input like a guitar amp or PA system and put out a very strong level.


Q: Will the Bottle 'O Blues microphone work with my amp?

A: In a word ... yes. I've personally played the mic through many amps and its always worked great. I've played through everything from new solid state amps, to vintage tube amps. I've sold thousands of them and have never had a customer tell me the mic did not work well with their amp.

Some of my personal favorite amps to use with the Bottle 'O Blues are:


Q: Will the Bottle 'O Blues microphone break if I drop it?

A: No, the mic is made from a strong plastic shell and is very lightweight.


Q: I'm getting feedback with my amp and mic. What can I do to reduce this?

A: Feedback with any mic and amp is a problem. The Bottle 'O Blues feeds back less than typical bullet mics like the Green Bullet, Bluesblaster, or Astatic JT30. But it can still be a problem.

The first thing to consider is the amp setup. Start with your gain and tone knobs turned all the way down. Slowly bring them each up one-at-a-time to see where feedback starts. Remember that its gain that causes feedback and a tone control is just a frequency selective gain control. Most feedback can be controlled by turning down the "treble" or "high" tone control.

If you're using a tube amp its very common for harp players to change the preamp tubes from the typical high gain 12AX7 (ECC83) tubes, to lower gain 12AT7 (ECC81) or 12AU7 (ECC82) tubes. These amps were designed for guitars and not microphones. Changing to a lower gain tube allows you to turn up louder and with more distortion before feedback occurs. Tubes are available online or at your local music store. They are easy to change but if you're not comfortable doing this, take it to a local music store and get them to do it for you. Remember to ALWAYS turn off and unplug your amp before touching anything inside it. Tube amps contain LETHAL voltages.

If you're using a solid state amp (no tubes), you'll need to follow the instructions above on setting up the amp, and in addition you may have to turn down the volume control on the mic to control feedback. Most solid state amps have VERY high gain becuase they are designed for guitar.


Q: I'm getting a buzzing sound through my amp. Whats going on?

A: This is almost always caused by a bad cable. Usually it means that the ground wire in the cable is broken. Try another cable to see if thats the problem. If the cable isn't the problem, try turning the mic all the way off using the volume knob. If the buzzing is still there, then you may have a problem with your amp.


Q: I'm getting feedback with my Smokey portable amp. Whats can I do?

A: The Smokey amp was designed for guitar and has very high gain which makes it tend to feedback with a microphone. Fortunately this is easily solved. Turn down the volume control on the Bottle 'O Blues microphone, and place the Smokey amp several feet away from the microphone.

A: As of May 2017 we're selling our own version of the Smokey amp with modifications to make it feedback less and have improved tone for harmonica. With this new version you won't have a feedback issue. If you have the original version of the Smokey amp and would like to get it modified for harmonica, contact Bottle 'O Blues and we'll take care of it for you.
