If you are looking for an acoustic mic emulator to save your money and get any of the fishman pedals they truly are amazing. This pedal gets rid of the jangly harmonics and brings that big warm acoustic sound through the amp. The Blend option can give tube warmth and compression to your guitar sound. It works well, versatile, noise-free, and multiple applications.

The "blend" control is really helpful in balancing the compression/saturation effect of the "level" control. The parametric band works well for finding an cutting that annoying mid-range tone on piezos. It is great for active or passive pickups.

Best With EQ: Fishman Great sounding preamp

Buy on Amazon

The fishman great sounding preamp's superior materials makes sure that it ages well with use. This thing will turn your guitar into a well oiled sound machine. It's a pleasant, vibrant sound, and the sweepable mid and treble controls dial down quack and brasssiness nicely. It does have a phase control and precision notch filter to help with feedbackand unwanted low-frequency resonance that often leads to feedback. The bass cut is wonderful for killing feedback, and the ground lift/XLR can help eliminate annoying buzz in venues with crappy electrics.

This allows you to just plug right into a mixing console or a Computer interface and know that you can adjust the sound of your instrument at a professional level and quality. It is easy to pack in a gig bag, and decently rugged. The compressor is also great, especially if you switch between finger picking and strumming as it can help keep your levels consistent.

The compression circuit, low pass filter, built-in tuner and adjustable boost features are most effective and appreciated.

• Works great on all kinds of active and passive basses and uprights
• 2 levels of low-cut to avoid low feedback rumble
• Works great mandolin with simple piezoelectric pickup
• Notch filters to help fight pesky feedback

The radial engineering unique direct box is suitable and reliable and fits well with your daily usage. Di is a unique direct box that is specifically designed for acoustic and orchestral instruments. It provides ample dynamic range for acoustic instruments. It features to impedance match the guitar pickup and pad the level down.

It is for active instruments such as acoustic guitars that incorporate a battery powered preamp, so you can engage a low-pass filter to gently soften the hard edge for a smoother more natural tone. This is followed by a fully variable high-pass filter that lets you'size the instrument' by gently rolling off bass frequencies to eliminate unwanted resonance.

• Adjustable load for piezo and magnetic pickups
• Variable low-cut filter to control bass resonance
• 48 v phantom powered, does not require batteries
• Very straight forward and natural sounding
