Like the GGP-02, the GGP-04 aims to level up the acoustic pickup game by promising to deliver five Impulse Responses directly from your instrument.
A handful of factory-equipped IRs aim to simulate the sounds of different acoustic body types, such as Auditorium and Dreadnought, and can be swapped out for self-made or third-party IR files via the onboard USB connection.
In practice, the pickup detects vibrations from your acoustic guitar strings and processes the ensuing sound in a bid to turn your small-bodied parlor guitar into a Grand Auditorium.
The accompanying control system features a small screen that signals which IR is selected, and houses control knobs for Bass, Treble and Volume.
According to Guitto, a range of reverb and delay effects have also been crammed into the GGP-04, which can be heard while playing unplugged via a Vibration Speaker Effects mode – it’s the same technology, in fact, behind the GGP-02.
There’s been no word on a price or a release date yet, so keep an eye on Joyo’s official website for updates.
