took it to mansons today, they're leaving it on in the store all day, but he thinks its maybe a faulty kettle lead which is good.
im still not convinced tho!? the amps wicked but ive only had it 6 months, and it already had to go in, im getting a very nice backup amp in the next to months and if i like it i may well get rid of the pro-6, as its really not as loud as they make out!
