Applications: Musical Instruments: No matter what instrument you have, the PyP-Bomb is the amp for you. The PyP-Bomb has been used a practice amplifier for instruments anywhere from electric guitar, bass, keyboard, acoustic and even harp. As long as you can come out of your gear with a 1/4" mono jack, you should be all set. All you have to do is plug it in to the line in jack on the PyP-Bomb, and start jamming. The Electric/Acoustic switch i specifically designed for electric vs. acoustic guitars, but can be used for any instrument you plug in. Each position will offer you a variation of sound that you can further modify with the full range tone control.   Public Address Systems: With the use of a microphone impedance matching transformer adapter you can plug a standard dynamic microphone into the PyP-Bomb without any additional requirements. The adapter we use is the Audio-Technica model number CP8201. Plugging this device into your microphone's XLR jack and then into the PyP-Bomb input, you are all set to go. Switching between Acoustic and Electric will give you a variation on sound that you can further modify with the tone control. For further power, connect two PyP-Bombs by using a 1/4" Y jack combined with the above adapter.   CD/MP3 Players: The NEW PB-1A has a built-in auxilliary port that allows you to plug your IPod or other standard CD/MP3 player right into the front panel and jam along with your favorite tune. If you would rather use the PB-1 PyPBomb, just attach a stereo-to-mono 1/4" adapter into the input jack, and you are good to go! This adapter will convert the stereo signal from your CD player into a single channel that the PyP-Bomb can recognize. Additionally, if you want even higher quality output, you can use a stereo splitting jack combined with dual PyP-Bombs to get full stereo reproduction of your IPod or other CD/MP3 player's stereo sound. When using the PB-1 PyP-Bomb we have used the Sound Professionals model SP-PHON-MINI-2 with great success.
