The Tone Stack calculator is designed to help you check out the design and response curves of a variety of tone stacks used in popular guitar amplifiers.

It is intended to be of interest to amplifier technicians, amp modifiers, hobbyists and students.

 

Key features

bluebox.gif (813 bytes) Tone stack types: Fender modern, Vox, Marshall, James (passive predecessor to Baxandall), Fender E series, Steve Bench tone stack, and now the Big Muff tone stack used in FX units.  Simply click on the appropriate tab to bring up a different schematic.
bluebox.gif (813 bytes) Components: Values can be altered simply by double-clicking on the component.  With potentiometers, the taper can also be altered.  The generator source impedance can be altered to give realistic simulation results for both cathode followers and common cathode drivers.
bluebox.gif (813 bytes) Bass/Mid/Treble: Slide the controls along and see the changes to the tone stack response in real time.
bluebox.gif (813 bytes) Snapshots: Freeze any trace so it can be overlaid by other traces.  Up to a maximum of 12 traces can be frozen in this way.  Can sweep the controls to show the range.
bluebox.gif (813 bytes) File Open/Save: Keep your favourite configurations on disk with this new facility.
bluebox.gif (813 bytes) Printing: Send the graphical results to your printer for a hard copy.
bluebox.gif (813 bytes) Other features: Online context sensitive help, variable plot resolutions supported to optimise performance.
