Which overdrive to choose
as its main ?

From barely broken clean to structured high gain: an overview of the 9 Teos Music pedals designed to become the backbone of your rig.

Building a guitar sound starts with choosing a base. Not a one-off effect, not a simple boost, but a its main around which everything else revolves. This is exactly what Teos Music's «Mon Son Principal» range is all about: pedals designed to play the central role of the pedalboard.

All share the same manufacturing philosophy - analog circuit 100 %, through-hole components, hand-assembly - but they don't all serve the same purpose. Some serve as a highly expressive low-gain base, others aim for the true main crunch, while others cover a wider range up to a structured high gain.

So the idea of this guide is not just to present the pedals, but to help you decide more quickly: Do you want a clear, dynamic base, an amp-style main crunch, a large gain range, or a more modern high-gain register?

Straight to the point

🟢

You want a low-gain base

You play a lot at guitar volume, you like the edge of breakup and you want to keep air under your fingers.

45 Overdrive, Liverpool Drive & Pre, Gladiator

🟠

Looking for a real main crunch?

You want the pedal to immediately give the feeling of a pushed amp, with more substance and a true lead sound role.

British Drive or Erebor

🔵

You want a wide gain range

You're looking for a single pedal capable of going from crunch to a more sustained lead without changing character completely.

Dirty Shire or 1987 Distortion

🔴

You're aiming for structured high gain

You need more saturation, but without losing definition, bass sustain and readability.

Silver Monster MKII or T-Express

If you're looking for a preamp rather than an overdrive

Your priority is articulation, body, dynamics and the sensation of a better-built signal, not necessarily a more saturated one.

Gladiator Preamp / Overdrive

🎯

You want to avoid a casting error

If you want a really big main crunch, avoid the Gladiator. If you want a very open low gain, the Silver Monster is obviously not the right place to start.

This scale gives a quick reference point, but the most important thing is the musical role. The 45 Overdrive and Gladiator are not far apart in terms of gain, yet the former aims for a british low-gain base, while the latter behaves more like a clear, articulate preamp.

The 9 pedals in the range

45 Overdrive

JTM45Amp-in-a-boxVintage
45 Overdrive – Teos Music

Gain

The range's British low-gain base: warm, supple, lively.

The 45 Overdrive is the natural entry point if you're looking for a warm, uncompressed main sound, highly sensitive to playback. It's reminiscent of early Marshalls with just the right amount of thrust: more an edge of breakup than a real heavy crunch.

With its controls Volume, Gain, Bass and Treble, It is easy to adjust to different amplifiers. True bypass. Compact 125B case. Not the right choice if you immediately want a dense, muscular crunch underfoot.

Ideal if : you play blues, classic rock, edge of breakup; you want a sound that reacts to guitar volume.

Liverpool Drive & Pre

VOX AC30Amp-in-a-boxClass-A
Liverpool Drive & Pre – Teos Music

Gain

The brighter, more open and more harmonic version of the main low-gain sound.

If the 45 is warm and round, the Liverpool is brighter, airier and more lilting at the top end of the spectrum. It's the one to choose when you want a base that breathes more, with a more obvious Class-A feel.

Works very well in always-on or stacking mode. Controls: Volume, Gain, Tone. True bypass. Not the best candidate if you're looking for a thick, dark main sound, or one with a strong low-midrange focus.

Ideal if : you like bright sounds with treble presence, '60s British rock, or stacking overdrives.

Gladiator Preamp / Overdrive

Dumble SSSPreampAlways-on
Gladiator Preamp / Overdrive – Teos Music

Gain

An expressive preamp before being a classic overdrive.

The Gladiator should not be seen as just another low-gain variant of the others. Inspired by Steel String Singer architectures, it is primarily used to structure the signal, add body, articulation and a high-end response feel.

Its Clean control lets you mix clear and saturated signals, and its Compression switch adjusts the response. Controls: Gain, Tone, Volume + internal Bass adjustment. True bypass. Not the best choice if you're looking for obvious saturation and a really big main crunch.

Ideal if : you're looking for an always-on preamp rather than a classic overdrive, or a clear, dynamic base in the spirit of Dumble.

British Drive Overdrive/Fuzz

PlexiglasMarshallOD + Fuzz
British Drive Overdrive/Fuzz – Teos Music

Gain

The real Plexi-type main crunch: immediate, lively, rocking.

British Drive is one of the most straightforward answers if you already know you want a crunchy, amp-like, classic rock-focused main sound. Its grain remains open, edgy and rich in the midrange, with that unmistakable Plexiglas feel.

Ideal if : you want a Plexi-type crunch with good dynamics, and the possibility of moving towards thicker fuzz-rock textures.

Erebor Crunch Drive

MarshallMetal PanelHard Rock
Erebor Crunch Drive – Teos Music

Gain

The extra notch if the British Drive seems too conservative.

Erebor remains in the Marshall family, but with more density, more bite and a more hard rock register. Its asymmetrical clipping gives it a lively, irregular grain, rougher than a smooth overdrive.

Simple controls: Volume, Gain, Tone. Dynamic response, good chord legibility even at high gain. True bypass. A straightforward option in the range. Less suitable if your priority is subtle low gain or bright, open sound.

Ideal if : you play hard rock, classic heavy, and you want an aggressive, lively crunch with a simple format and price.

1987 Distortion

RATDistortionVersatile
1987 Distortion – Teos Music

Gain

The most “distorted” candidate of the selection, with a real usable range.

The 1987 differs from amp-in-a-boxes in that it is based on a more straightforward logic. distortion pedal, This is a Rat-type circuit, but with more progressiveness and control than is often expected from this family.

The CUT control plays a central role: it precisely adjusts the treble response, allowing you to move from a dark, compact sound to an open, biting distortion. Buffered bypass for stable integration in large signal chains. Not the best choice if you're primarily looking for the feel of a very natural low-gain amp.

Ideal if : you're looking for a versatile, progressive distortion that can be used from crunch to dense saturation, with real control over the treble.

Dirty Shire Overdrive

FriedmanMarshallModern rock
Dirty Shire Overdrive – Teos Music

Gain

The most versatile if you want a single pedal to hold the main position.

The Dirty Shire covers a wide spectrum, from vintage crunch to firmer, more defined saturation, with no break in character. It's probably the most obvious if you want to a single pedal that can do a lot without losing its coherence.

At low gain, it remains warm and organic; on the way up, the bass holds together better, the attack becomes more forthright, in the spirit of the modern Friedman. Active 3-band equalization, Presence, Tight, internal trimmer for overall gain. True bypass. Less relevant if you're looking for a very simple or ultra-specialized typeface.

Ideal if : you want a single pedal that covers everything from vintage crunch to saturated lead, with a real amp feel under your fingers.

Silver Monster Distortion MKII

Soldano SLO-100High GainPreamp
Silver Monster Distortion MKII – Teos Music

Gain

The direct choice if your main sound is modern high-gain.

The Silver Monster MKII is the most naturally high-gain-oriented offering in the range. Inspired by the Soldano SLO-100 architecture, it functions as a true saturation preamp, dense but legible.

Sound Low/High Gain selector offers two distinct structures: the low mode remains articulate, the high mode moves towards massive but sustained saturation. 3-band equalization, Presence, Deep switch. True bypass. This is obviously not the right way in if you're aiming for the edge of breakup or light crunch.

Ideal if : you play modern rock, hard rock or metal, and are looking for distortion that remains defined and structured even at high gain.

T-Express Overdrive/Preamp

TrainwreckPreampDynamics
T-Express Overdrive/Preamp – Teos Music

Gain

The most responsive and responsive choice in the entire selection.

The T-Express occupies a unique place in the range: it's the only pedal inspired by the legendary Trainwreck Express. It delivers high gain with low immediate response to attack here, the sensation of speed and nerve is almost as much a part of the sound as the equalization.

Ideal if : you're looking for an expressive overdrive with high gain and extreme dynamics, and you want to control your timbre finely via several switches.
