Full-range boosters are often thought of as simple circuits that just lift the entire frequency band equally, but when it comes to adding musical elements to them, it is a very difficult effector to design. Though there are many boosters specialized for electric guitar, this pedal will clearly reproduce the full sound image of any stringed instrument - including bass, acoustic guitar, etc. 

It uses the same op-amp design as the HUMSTER Ultimate pedal, but due to a narrower feature set, the circuit fits in a smaller enclosure, while still retaining the ability to be powered by a battery. The gain on this low-noise circuit can be adjusted up to +18dB and will surely prove useful if you meet an amp with a poor gain stage at jam session or studio. This tiny booster will easily fit in the pocket of your gig-bag and accompany you everywhere!

 9V battery and AC adapter are sold separately.
