DESCRIPTION:
In this second of a two-part video series featuring the design and function of tube amplifier (passive) tone stacks, the following topics are covered: 1.) A brief review of Part 1 2.) How to determine the cutoff frequency of high and low pass filters 3.) How to change the cutoff frequency of a filter 4.) A side-by-side comparison of Fender and Marshall tone stacks 5.) The audio spectrum of Fender, Marshall, Vox, and James (passive Baxandall) tone stacks (utilizing the Duncan's Amp Tone Stack Calculator) 6.) How to change a Marshall amp's audio spectrum into that of a Fender amplifier (as a demonstration of the Calculator's capability).

All topics are explained in easily-understood language for those who are seeking a basic understanding of tube amplifier design and function. For those who are ready to take a step-up in technical sophistication, the formula for calculation of cutoff frequency is presented, and its application to guide the modification of tone circuits is explained and demonstrated.

In addition, Rusty makes a guest appearance and faces the toughest test of his video career. It's definitely a must-see for all his fans :)
