Three in one is the main motto here. Guitars, that is...
The idea is to avoid having to plug and unplug different guitars in to one amp.
With the TRINITY you can selectively switch three instruments to one output.
In addition each input can be boosted up to +12dB by an individual stepless pot.
This helps to balance out differences in level between the instruments without having
to change the amps settings. Quietly and easily switch instruments.
Comes with a convenient tuner output.
Uses a standard 9 volt DC power supply -- 120 mA minimum (not included).
