The AMT Electronics AMT FX O-Drive mini is a compact JFET distortion pedal designed, in the maker's words, for guitarists looking for distortion sounds similar to the Orange TT* amplifier1. It is part of AMT's Drive Series, a family of drive pedals intended to be connected in front of the clean channel inputs of guitar combos or amplifiers, so the pedal rather than the amp supplies the distortion1. The pedal is listed as available now1.

Sound and design

AMT describes the O-Drive mini as built around new original circuitry solutions developed by its own specialists, based on what the company calls real actual tube stage emulation and response1. The target is the character of the Orange TT* amplifier, and the pedal carries the "mini" designation used across AMT's compact Drive Series line1.

One thing to know before plugging in: the O-Drive mini does not have a cabinet simulated output, unlike AMT's Legend Amp Series pedals1. It is a pedal for feeding a guitar amp input, not a direct-recording preamp.

If you need a cabinet simulated output for going direct into an interface or power amp, AMT points to its Legend Amp Series instead; the O-Drive mini does not include one1.

Controls

The pedal keeps things simple with three knobs and one switch1:

ControlWhat it does
GAINDetermines the pedal sensitivity and the amount of drive or distortion1
TONEA simplified control for general tone matching of the pedal to your amplifier1
LEVELSets the overall output level, from a standard minimum of -10dB up to +8 dB at maximum1
VOICEA switch to cut some mids1

The Level knob's range is worth noting: with a floor of -10dB and a maximum of +8 dB, it covers both a cut below unity and a substantial push into the front of an amp1. The Voice switch gives a one-move mid cut, a quicker way to reshape the sound than working the Tone control alone1.

Power and bypass

The O-Drive mini runs on a standard 9V DC supply with negative center polarity, the common pedalboard convention1. Its voltage consumption is low: AMT specifies less than 4mA, which is light enough that nearly any supply output can handle it1.

Bypass is true bypass, and AMT states there is no tone coloration, signal degradation or loss while the pedal is not in use1.

Where it sits in the Drive Series

The O-Drive mini is one of a family of compact AMT drive pedals, each aimed at a different amp-style flavor. Others in the line covered on Tonebox include the S-Drive mini, P-Drive mini, M-Drive mini, VT-DRIVE mini, C-DRIVE mini, E-DRIVE mini and B-DRIVE mini. AMT's media center groups these under the Drive Series heading2. For a broader look at the effect type, see Distortion Pedals.

Questions

What does the Voice switch do on the AMT O-Drive mini?

The Voice switch cuts some mids. It is a quick way to change the character of the distortion without touching the Tone control, for example to open up a sound that feels too thick or crowded in the midrange when the pedal is matched to your amplifier.

Is the AMT FX O-Drive mini true bypass?

Yes. AMT Electronics specifies true bypass circuitry, and says the pedal causes no tone coloration, signal degradation or loss while it is not in use, so your amp's own tone comes through unchanged when the effect is switched off.

What polarity does the O-Drive mini use?

The pedal requires a standard 9V DC power supply with negative center polarity, the same convention used by most modern pedalboard power supplies.

Does the O-Drive mini have a cabinet simulator?

No. AMT notes that the O-Drive mini does not have a cabinet simulated output, unlike the company's Legend Amp Series pedals. It is meant to feed a normal guitar amplifier input rather than a recording interface or power amp directly.

Should the O-Drive mini go in front of a clean channel?

Yes. AMT designs its Drive Series effects, the O-Drive mini among them, to be connected in front of the clean channel inputs of guitar combos or amplifiers, where the pedal supplies the distortion rather than the amp.

How much level range does the Level knob cover?

The Level control sets the pedal's overall output level. Its range of adjustment provides a standard minimum of -10dB and reaches +8 dB at maximum, so it can go from a slight cut to a healthy boost above unity.
