Choosing the Right Fader for Expression

Not all expression pedals and faders work with all pedals. Here’s some quick guidance on how to select the right fader.

There are 2 variables that you need to consider when matching an expression controller to your pedal:

1. Topology - in all of the configurations the sleeve of the jack is connected to the “bottom” of the potentiometer:

   • TRS - the most common configuration, with the ring of the jack connected to the top of the potentiometer, and tip connected to the wiper of the pot,

   • RTS - similar to the TRS connection, but with the tip and ring connections swapped, and

   • TS - a 2-conductor configuration where the wiper and top of the pot are both connected to the tip of the jack

2. Resistance - each vendor suggests a resistance value or range of resistance values that work with their pedals.

So, both topology and resistance need to be considered when selecting the right expression Fader for your pedal. But how do you figure out what you need?

1) Ask me, and I’ll happily go figure it out for you, or

2) Check with the vendor of your pedal and see what they recommend, or

3) Check this useful reference.

Fader and Fader DLX are offered in a range of resistances, and natively support the TRS topology. Other topologies can be supported with a simple custom cable. If you’re in need of such a cable to match a Tall Timber Fader to your pedal, please let me know and I’ll help you get it sorted out!

If you’re keen on making up a cable for yourself, here are some common (and uncommon!) cable diagrams. Have at it!
