Boss Acoustic Singer Live Amp Review
This new amp from BOSS is a 60-watt bi-amp design with custom-designed woofer and speaker and has taken the acoustic stage amp to new levels in functionality and sound quality. Dual channels with dedicated 3-band EQ for vocal and guitar allow the performer to produce studio-quality sound anywhere.
The dedicated guitar channel features the ‘Acoustic Resonance’ feature which restores the natural tone and body so often lost when using piezo pickups in an acoustic guitar, two types of chorus effect and an independent reverb developed with the acoustic guitar in mind. And the result? The guitar tones are vibrant and rich with the reverb adding some nice depth to the overall sound.
The limitation with the chorus and reverb effect (and this is consistent with most effects on an amp) is that the knob really only controls the depth of the effect and parameters cannot be controlled. When dialling in the reverb this is not so much of an issue in a live setting, but the chorus effects can benefit from control over the rate and other parameters to allow for much more usability in live settings.
The guitar channel also has a phase switch and notch control for helping to control feedback. Amplifying an acoustic guitar can be a tricky thing to do, and to do it well even more so. Feedback issues are common at volume and having a notch filter to knock out the offending frequencies is very useful.
The vocal channel features a combo XLR/jack input with the option of adding phantom power for using condenser mics with the amp, an independent 3-band EQ for tone shaping, independent reverb and a harmony feature. I haven’t seen this offered on an amp like this before, but it is incredibly useful for the singer-guitarist. Harmonies are generated from the guitar chords in real time. This can really add to a solo performance over the course of a gig.
As with the guitar input, the mic channel also features anti-feedback controls which is incredibly useful at live gigs. Howling feedback is never a good thing!
The amp also has a looping function which can be used to develop ideas, for practice and enhancing live performances. When playing a solo gig I often lay down chords while singing a verse of chorus (or both) kick in the loop and then take a solo over the top of the loop. Vocal loops can also be sued to build up a stunning performance.
To activate the looper, harmony and effects you can use an optional foot switch. For live use this is essential!
Overall I am very impressed with this amp. As an acoustic instrumentalist and a singer-guitarist, this little amp would be a great addition to the kit, especially for very small and intimate gigs where a PA is not possible, outdoor gigs such as weddings where it could be run from a battery, or onstage in a club as a monitor and then the signal sent from the XLR outs to the mixing desk and then front of house.
If you are a solo singer-guitarist the BOSS Acoustic Live amp is well worth looking into!
