"It’s the most musical, best sounding OD pedal I have owned in more than twenty-five years bar none. If you are concerned with tone, you have to check it out."

Features & Specifications

The Radial Trimode offers an amazing combination of simplicity and functionality with innovative, well thought-out features accessible through intuitive controls and i/o options.

The two footswitches provide for easy toggling between modes and large LED indicators allow instant at-a-glance monitoring of the Trimode's status.

Separate drive, level and mid-boost control for each distortion channel gives the user the power to easily set up exactly the distortion sounds required, then toggle between them with no tap-dancing!

The overall TOP END and DRIVE GAIN switches together with variable HIGH and LOW EQ controls and the 'anti-presence' FILTER control will guide you to the perfect tone for your amp/guitar combination.

Effects can be connected via the INSERT ¼" send-receive TRS jack and are switched in when you press the 'Toggle' switch to select CH-2.

High distortion (+20dB)
Intermediate drive: (Intergain™)
Variable fine-tune gain for CHANNEL-1
( rhythm) - counter-clockwise for more gain
Drive-1 & 2 controls: Used in conjunction with the drive gain switch, drive is used to adjust the overall amount of gain to the overdrive circuit.
Mid Boost 1 & 2 - two 3 pos switches: Used to fatten up the sound for more cut and sustain during solos. Also, will fatten up the sound of single coil pickups.
