Since purchase amp always had a hum unless I touched strings. Last month the amp spiked when I turned Standby ON. Since then lost power on Classic channel and selector switch on head would not change channel, but footpedal works. I returned to Sweetwater for repair/replacement immediately. I received back stating "Reverb PCBA pins were lifted halfway off Main, glued in place. Bias the output tubes...". At this time I purchased Gibson cables CAB12-BL thinking the hum from bad Sweetwater cables supplied. Still have hum at 1/4 volume, min Gain setting and the Channel Select on head still does not work. It used to, and hum acceptable at low volume. Is this correct, can I get replacement?
Hello Rick,
If you could please confirm the model of the head?
As the warranty if with Sweetwater if you are still not happy with the amplifier after the repair you need to contact them and arrange for it to be looked at or replaced. As the warranty is with them we cannot approve a replacement on their behalf.
