Excerpt: I bought this pedal for my Classical electric because it was without a built in preamp. It has plenty of gain, and is very clean. The treble and bass controls help to balance the sound to make it natural sounding.
Summary: All I can say is this is a great boost pedal for the money and I'm really happy with it. It's perfect for playing lead guitar, but everything boosts nice too. It will also down boost too for song's like creep where the distorted heavy guitar drops to a lower volume towards the end of the song.
Summary: Somewaht disappointed in this preamp. I have had several other Behring products that I liked. The BP100 provided very little increase in signal. I had to turn up my line amp up just as loud as without the preamp.
Summary: I purchased the PB100 for my own use, hoping to enhance my sound. It came with no power supply or manual. It worked great for about 2 weeks. Then it just quit. Behringer support is difficult in the least, like trying to drive through a obstacle course in a snow storm.
Summary: I bought this pedal to boost the level of my guitar for lead solos, and it does a great hob of it. It is quiet and simple and does exactly what I wanted it to do and the price was unbeatable. Although it is made of plastic it seems to be well made.
Summary: The unit works ONLY with 1/4" mono plugs otherwise it will not turn on. But even then the amplifier would not operate, it was defunct. It is a foot switch. Nice solid construction. No power supply included, needs a 9V battery. Buy some thing else. I am returning it.
