So I've had my DynaVerb for about 2 months and have used it on 3 gigs and a modest amount of time in the studio. I love it, but it's become a bear to keep 'fed' properly. In that time it's already gone through 2 9V batteries and makes a horrible racket when the batteries start dying... the sort of sound that a guitar amp makes when it's banged and the reverb coils start shaking. When it first happened I thought I had a blown speaker in my cab with all the racket and distortion. I have an EBS power supply on the way for it to hopefully remedy the situation, but I guess my question is whether or not it's normal for this pedal to eat batteries like this. I'm assuming that the batteries are engaged even if the pedal is not activated since they're dying so quickly. Anyone else have this experience?
