I have delay DD500, tuner POlytune 2 and Looper DITTO x4. 600 € in 3 effects and I can get one TREX for 600 € too with more options and suitable for acoustic guitar. I like having all good staff under one roof and not to bring 5 effects together when I have a concert.
I am thinking about BOSS AD10 too guys, but there some negative reviews and I have dd500 > too complicated. I have a little daughter dont have time for all the setting. I need only turn the knob and play not to experiment so much. BOSS AD 10 is too complicated and 1 little display. I am towards TREX too.... But I must sell the mentioned staff I already own
