PG's Brett Petrusek is On Location in Nashville, TN, for the 2010 Summer NAMM Show where he swings by the Randall Amplifiers booth. In this segment, we get to check out one of their newest heads--the RT503. The RT503 is a 50 watt, 6L6-loaded (can also come with EL34s), 3-channel amplifier. Its three channels include, Channel 1 - Classic Clean - from sparkling to highly overdriven, Channel 2 - Classic Overdrive - from mild grit to full saturation, and Channel 3 - Modern Overdrive - full hi gain tone. Each channel's controls include Bass, Middle, and Treble (Channel 1 has a Bright switch) and the master controls are Volume and Reverb.

When power cables and signal paths tangle, the results can be noisy. Here are some easy fixes.

In my previous State of the Stomp ["The Shocking Truth About Ground Loops," October 2021], I discussed how ground loops can be formed between the amplifiers in a multiple amp setup, and how to safely address them with an isolation transformer. As a brief reminder, a ground loop is created whenever two electrical circuits that theoretically have the same ground potential actually have a non-zero potential between them in practice, and that often results in hums and buzzes that are harmonically related to the mains voltage frequency in your part of the world.
