Expert Tips: Biasing Marshall 1987X Tube Amp for Best Tones Sound. Matched tubes help! This 50 watt amp is shown how I bias tubes with the Bias Master too.

I recently bought a Marshall 1987X reissue 50w amp and decided to show how to bias the amps after a tube change. There's lots of useful information about tubes, matching etc. and shows how to do things the easy way. This video shows the TAD Bias Master in use too on a real amplifier and a few things about two new tubes that were mismatched and how to solve that.

Later Ill be making a video of how to convert this amp to master volume and some other nice tweaks and in this video I show why I chose this amp as the platform... and not an original 1987 50 watt amplifier.
