Pedal Trio #1 – Synthy Bass Flavors

This very first Pedal Trio mashes up an octave pedal, and envelope filter and a ‘slow engine’…

Note! The Pedal Trio concept is brand new. Read more about the idea behind it…


It’s always fun to create fake synth bass sound using nothing but pedals and a bass. There are plenty of different ways to achieve this, but a classic approach is to use an octave pedal and isolate the sub octave. This method goes all the way back to the original Boss OC-2 pedal and it is still a favorite for many bass players for this exact purpose.

There are, however, a number of modern octave pedals that has a few additional tricks up their sleeves. The COG T65 is one of them, and that was the pedal I chose as the starting point for this combo exercise.


SOLO – COG Effects T65 Analog Octave

The T65 offers a sub octave as well as an octave above the clean signal. The upper octave is by no means designed to replicate the original tone as precisely as possible only an octave above. It is more meant as a tool that adds significant tonal coloration to the table.

In fact, it has a touch of overdrive and in isolation it almost has a slight Fender Rhodes vibe to the tone.

Further, there is a filter knob that alters the nature of the sub octave quite heavily. I decided to set the filter knob at noon, which adds some ‘hair’ to the otherwise round and sine-like sub octave, as well as blending in the upper octave.

While it appears to be a 50/50 mix between the sub and upper octaves, the upper merely adds to the character rather than a distinct note above.

As the goal was to aim for a synthy sound, I cut out the clean signal entirely, and the optional loop feature (you can insert external pedals via a Y-split cable in the signal path) is not in use.

This is the first thing that came up when I had dialed in this tone:

DUO – Adding Boss FT-2 Dynamic Filter

Boss’ FT-2 is an old favorite of mine. It may be because it was my first envelope filter pedal, but it has followed me for several decades by now and I do love the sound of it.

Usually, I can dial in a sound that blends in nicely without becoming overly ‘zappy’ or ‘quacky’ (both can be cool, BTW), but just nice and bubbly funky…

TRIO – Slowing Down with Mooer

To complete the trio, I wanted to try to really change the sound in a fundamental way. To a degree where it had a direct impact on the way I would play with this new sound.

What better way to do that than mess around with the attack of the tone.

Mooer’s Slow Engine does exactly that, and even though I dialed in a very subtle setting, I instantly changed the groove to adjust to the slowed down attack curve.


Well, so far so good. This first Pedal Trio was fun to make, and more will follow soon, so please do stay tuned!
