Most of you know I am a musician by choice and once upon a time, career. To be specific, I am an acoustic guitar player. Although I can play other instruments and electric, I pretty much suck on most except acoustics.
I came across something acoustic guitarist should have: The D-TAR Mama Bear. It is a pre-amp for acoustic guitars. On stage, acoustic guitars are hard to make work right particularly in loud venues or rock bands. One reason is the guitar acts like a microphone and that means its internal pick-ups have to be turned down. Another is most guitars, particularly inexpensive ones, use a piezo pickup on the bridge and that is a very thin sound without reinforcement. As a result, guitarists have different combinations of pickups and live mics to get That Wooden Sound. It is all a compromise and can be a pain to manage in different rooms.
Also, an acoustic guitar, depending on the wood used, the design and the talent of the luthier (guitar maker, don't bother looking it up), only makes a limited variety of sounds.
Enter Mama Bear. This pre-amp not only enables a much quieter live sound, it acts like an emulator, software/hardware to make one guitar sound like another. These beasties are usually very pricey. The Mama Bear is right in that sweet spot between $300 and $400 that a weekend warrior can afford.
Go to the D-TAR page and watch the video with John Jorgensen if you are into this. It is well worth it.
