General

The Acoustic Singer Pro by BOSS is a practical guitar amplifier for acoustic guitarists and singer/songwriters. Its packed full of possibilities to take your performance to the next level. It has two channels so that you can connect an electro-acoustic guitar and a condenser microphone, for instance. On the guitar channel you can add two different types of chorus, while you can add delay or echo effects to the mic channel. Both channels also offer you the possibility to add reverb and have anti-feedback controls to resolve any problems in this area.

Harmonies, looper and Acoustic Resonance

As well as the effects mentioned above, this 120-watt Acoustic Singer Pro has a few other tricks up its proverbial sleeve. The mic channel gives you the ability to add harmonies to your vocals letting you choose between low, unison and high. For guitarists, there's a built-in looper function that really lets your creativity run wild. Instruments with piezo pickups sound more natural and get extra body thanks to the Acoustic Resonance feature. With a number of different connection possibilities, BOSS's Acoustic Singer Pro is the ideal amp whether you're practising, recording or performing live.

Deze acoustic Singer Pro 120W van Boss overtreft al mijn verwachtingen. En hij is boven verwachting niet zo groot qua omvang maar wel zo groot in prestatie.

Supermooi warm geluid en veel mogelijkheden om aan je sound toe te voegen. Mijn dochters zijn ineens heel gemotiveerd door de extra's en de lol die het spelen op deze versterker met zich mee brengt. Ik heb de de fishman artist er naast gezet en de acus 6t. Acus klonk het mooist maar heeft weinig extra's, fishman is erg zuiver maar vond tot mijn eigen verbazing toch de boss wat lekkerder klinken. In ieder geval voor de dingen die ik er mee doe.

leuke van deze versterker is dat je er zo veel leuke dingen mee kan doen dat je meteen gemotiveerd ben om je gitaar weer eens op te pakken. Twijfelde even of ik niet meer zou geven om het beste geluid, maar ben blij dat ik deze versterker heb aangeschaft. Juist de extra effecten geven deze versterker meer jeu.
