Hi there, i`m new here and i just bought a brand new QR, in part from reading this board every damn 15 minutes....LOL The amp is just amazing and tone is sweet as hell. I have only one worry. There is a hum i can hear at all times. I have unplugged everything, loop disengaged with cables out, no input. Just the power cord and speaker jack. Full power, 16 ohms in a 16 ohms VHT cab. 1st gear i can hear it, 2nd gear becomes louder and 3rd gear is quite anoying. With the boost ingaged it`s even worst. It`s quite loud. Clean channel you can hear it just a bit, but barely. What causes this? Is it normal? It shouldn`t be this loud. I can hear the hiss increase with gain, wich is a normal high gain hiss, but the hum is bothering me. It seems like an electrical hum. I have 2 other amps here and they don`t do the hum, so it`s not my wall plug. I`m really concerned about it, i hope there`s no internal damage  Thanks for your help on the subject, Chris |

BTW...welcome 7string...I have WAY too much on my hands with 6.... |

Hey thanks for the reply.
I forgot to mention that my footswitch was plugged in, never thought it could be that...But it was !
AS soon as plug it in, the hum starts. Ground problem?
I contacted Scott by email and i`m waiting on his response.
Now it`s quiet but, there is a very very slight hum, i guess this one is normal. If i put my gain on zero, with nothing plugged in, and crank the volume, there is a slight hum and gets louder till full volume. But it`s not very loud. Does anyone else`s amp have this little hum?
Thanks a lot.
Chris

Thanks a lot. Chris Mine is only noisy when I don't use the Splawn Footswitch and use my extra one. It probably is a ground issue. The other possibility is a preamp tube- usually the first one is the culprit. |

Yep...not everybody wires their footswitch the same...so yes it could create noise.
