just got a brand new trippy MB – I think I have a problem withe the feedback knob – all the demos I see on utube and ehx players are setting the feedback knobby to 12:00 and better without runaway – I can’t get mine past 10:00 b4 it starts trippin out – any suggestions or do I have a defective pedal – still a very cool delay – I was always accustomed to digital till I bought a couple of EH pedals – I now own a G4BM,LBM,POG,&MB;- replacing all boss stuff fom the 80’s- The POG is one of the coolest things I have ever owned!!! – P.S On the MB another trick I learned is if u plug in a dummy plug to the EXP input the delay tmes get a good bit longer – don’t know why but it does
