The GDI 21 is a success value for money.
I bought that starts with the acoustic version (ADI21) which is a real massacre, a takamine santa fe it is connected as its exellent soaked bass and harmonies.
erant more than happy laa versiosn acoustqiue j bought the 21 I use GDI directly plugged into my mixer and the sound is really hell, I particularly love the sound quality clear style fender

UTILIZATION

Very easy to use buttons 4 and 3 selectors amp it can regret the absence of memory to recall the settings but that price should not push.
correct sounds are thick and rich in harmonics, and a lot marshall fender super stunning

SOUND QUALITY

A Start plugged into this little pedal is extra, if you like bein on the hyper sound filters through 15 pedals it will seem basic, but if like me you like the style guitar amp reverb you will be pleased the size of the amp puique within the pedal returns to cover any scratches

OVERALL OPINION

I tois months from the User and I'm happy! * A go for that price
