The first issue was no bluetooth communication with my Ipad. I now use a Kindle fire and it's working great. Now I will be playing a preset and the volume drops out to almost nothing. Has anybody discovered a fix? This is a Code 25 I really want to love this amp because when it works it's great. The problems it has are making me fall out of love fast. I expected a lot more from Marshall, I have almost all Yamaha product and never have problems.
