The Dedalo B-saurio is a bass distortion pedal from Dedalo Fx, an Argentine brand of pedals. It is an analog circuit using IR-LED/FET clipping, and its defining feature for bass players is a Blend control that adds a clean, low-pass filtered signal in parallel with the distorted one, which the maker says enhances the impact of your low frequencies. Dedalo describes it as a pedal that "simply has the greatest distortion power for your bass"1.
The controls
The B-Saurio carries five knobs, split between shaping the distortion and managing the clean blend:
| Control | What it does |
|---|---|
| GAIN | Amount of gain applied at the input of the pedal. This gain is centered around the low and mid-low frequencies, and allows you to get sounds with more weight and growl. |
| DIST | Gain of the distortion stage. This control is centered on the higher mids, and allows you to get high levels of distortion on that range of frequencies. |
| TREBLE | Treble control. Turn to the right for an open and bright tone, and to the left for a darker sound. |
| LEVEL | Output level of the effect. |
| BLEND | Level of the clean signal, which is added in parallel to the distortion. This clean signal is filtered to keep only the lower frequencies, and allows you to get the desired bottom end in all levels of distortion. |
The two gain controls work in different frequency bands: GAIN pushes the low and mid-low frequencies for weight and growl, while DIST drives the higher mids. The BLEND knob is the one aimed squarely at bass players, since it lets the low frequencies pass through clean underneath the distorted signal1.
A single footswitch turns the effect on and off. Because the pedal is true bypass, the switch keeps your sound intact when the effect is off1.
Power and connections
The B-Saurio runs on a 9V DC supply with center negative polarity, and it can also run from a 9V alkaline battery. Dedalo Fx specifies a current draw of 25mA at 9V DC1.
The pedal draws 25mA, so check the current rating of any daisy-chain supply you plan to share it with, and use an isolated or adequately rated output where possible.
The input impedance is 750Kohm1. Physically, the pedal measures 12cm x 9.4cm x 5.4cm, weighs 475gr, and comes in a black enclosure1.
About Dedalo Fx

Questions
Is the Dedalo B-Saurio true bypass?
Yes. Dedalo Fx lists the B-Saurio as true bypass, and the true bypass footswitch turns the effect on and off while keeping your sound intact when the effect is off.
Is the B-Saurio an analog or digital pedal?
The B-Saurio is an analog pedal. Dedalo Fx describes it as an analog circuit with IR-LED/FET clipping, the component pair that shapes the distortion.
What does the Blend knob do on the B-Saurio?
Blend sets the level of a clean signal added in parallel to the distortion. That clean signal is filtered to keep only the lower frequencies, so you can keep the desired bottom end at all levels of distortion.
How much current does the B-Saurio draw?
Dedalo Fx specifies a current draw of 25mA at 9V DC.
