Key takeaways
- Battery use: Most of these pedals accept a 9V battery, but distortion pedals with LEDs and high-gain circuits can drain batteries quickly when left plugged in. Unplug the input cable when the pedal is not in use.
- Power supplies: Check polarity, voltage, and current requirements before using a daisy chain. A compatible isolated supply generally produces less hum, especially with several digital or high-gain pedals.
- Headroom: A pedal can sound harsher through an amplifier already operating at maximum saturation. Lower the pedal’s gain and raise its level first; this often produces more definition.
- Switches and jacks: Footswitches, input jacks, and battery clips are common wear points. Avoid pulling patch cables sideways and secure the pedal so it cannot move when switched.
- Cleaning: Wipe the enclosure with a dry or slightly damp cloth. Do not spray cleaner into pots, footswitches, or jacks. Crackling controls may need professional servicing rather than repeated forceful turning.
The best distortion pedal for most players is the ProCo RAT 2: it covers gritty classic-rock drive through aggressive distortion, has useful filter control, works with many amplifiers, and stacks well with both clean boosts and overdrives.
That is not the right answer for every rig, though. A Boss DS-1 is cheaper and brighter, an Ibanez Tube Screamer TS9 is better for tightening an already distorted amp, and a Boss MT-2 Metal Zone offers far more gain and EQ control for modern metal. The right choice depends less on maximum distortion than on how the pedal interacts with your amplifier, pickups, other pedals, and playing style.

| Situation | Best choice | Why it fits | Typical market range in 2026 |
|---|---|---|---|
| Low-cost first distortion pedal | Boss DS-1 | Simple controls, recognizable rock sound, durable enclosure | $50–$75 |
| One pedal for classic rock through hard rock | ProCo RAT 2 | Wide gain range and a useful filter that adapts to bright or dark amps | $80–$110 |
| Boosting a tube amp or tightening high gain | Ibanez Tube Screamer TS9 | Mid emphasis and bass reduction help riffs stay focused | $100–$140 |
| Modern metal and extreme gain | Boss MT-2 Metal Zone | High-gain circuit plus separate two-band parametric-style EQ | $100–$130 |
| Fuzzy, sustaining alternative rock | Electro-Harmonix Nano Big Muff Pi | Large sustain, compressed attack, and thick low-mid character | $90–$110 |
Head-to-head comparison
| Pedal | Gain range | EQ control | Power | Amp compatibility | Stacking behavior |
|---|---|---|---|---|---|
| Boss DS-1 | Low to high distortion; less saturated than a metal pedal | Single Tone control, strongly affects treble | 9V battery or Boss PSA-series 9V DC supply | Best with clean or mildly driven amps; can sound thin into bright solid-state amps | Good after a boost; can become fizzy when stacked with another bright distortion |
| ProCo RAT 2 | Overdrive-like breakup through thick, compressed distortion | Filter control rolls off high frequencies; Volume and Distortion are independent | 9V battery or compatible 9V DC supply | Works with clean, edge-of-breakup, and many high-gain amps | Excellent with boosts and overdrives; stacking two can become compressed and noisy |
| Ibanez TS9 | Low to medium overdrive rather than saturated distortion | Single Tone control plus a built-in mid-focused voicing | 9V battery or compatible 9V DC supply | Particularly effective into tube amps and already-distorted channels | Excellent as a tightening boost; less useful if you want scooped, bass-heavy rhythm tone |
| Boss MT-2 | High gain through very high gain | Level, Distortion, Low, High, Middle, and Middle Frequency controls | 9V battery or Boss PSA-series 9V DC supply | Flexible, but requires careful EQ; often clearer into a clean amp than into a saturated amp | Usually best alone or after a tight boost; too much gain before it quickly becomes indistinct |
| Nano Big Muff Pi | Medium to high fuzz distortion with long sustain | Volume, Tone, and Sustain; Tone is broad rather than surgical | 9V battery or its specified 9.6V DC adapter | Strongest into clean or slightly driven amps with enough headroom | Can overpower low-output drives; pairs well with a clean boost or a focused overdrive after it |
Which pedal has the most useful gain range?
ProCo RAT 2: the broadest practical range
The RAT 2 is unusually versatile because its Distortion control changes more than the amount of grit. At lower settings it can behave like a rough, compressed overdrive; higher settings produce the saturated sound associated with alternative rock, punk, and hard rock. Its Filter control works in the opposite direction from a conventional tone knob: turning it up removes treble. That makes it useful for taming a sharp amplifier or bright single-coil pickups.
The RAT is a strong choice when one pedal must cover several bands or songs. It is less ideal if you need an extremely open, touch-sensitive overdrive or a perfectly clean low-gain boost.
Boss DS-1: classic rock value
The DS-1 delivers a hard-edged, cutting distortion that suits classic rock, punk, garage rock, and ’80s-style lead sounds. Its Tone control can add presence, but high settings may emphasize fizz. Into a dark tube amp, that brightness can be helpful. Into an already-bright amp, keep the Tone control closer to the lower half of its range and raise the amplifier’s mids rather than simply adding more distortion.
Its limited EQ is part of the appeal: beginners can get a usable sound quickly. Players seeking thick low-end rhythm tones or detailed modern metal shaping will outgrow it sooner.
Best EQ control: Boss MT-2 Metal Zone
The MT-2 has the deepest tone-shaping system in this group. Along with Low and High controls, it provides Middle and Middle Frequency controls. This lets you choose both how much midrange is present and which midrange area is emphasized or cut. That is far more precise than the single Tone knob on a DS-1 or TS9.
More control also creates more opportunities for poor settings. A heavily scooped middle and maximum gain may sound impressive alone but disappear when drums, bass, and another guitar enter the mix. Start with the Middle near noon, set Middle Frequency near the center, and increase gain only until palm-muted notes remain distinct. For a live band, a moderate mid boost is usually easier to hear than extreme bass and treble.
Best pedal for boosting and stacking
The TS9 is the classic choice for stacking because it cuts some bass, emphasizes the mids, and compresses the signal before it reaches a distorted amplifier. This can make loose low strings feel tighter and help lead notes stand out. It is not the best choice when you want the boost to preserve every part of a wide, scooped guitar tone.
A useful high-gain chain is guitar → TS9 → MT-2 or amplifier distortion. Set the TS9 Drive low, Level high, and Tone according to the brightness of your guitar. The aim is usually to push the next stage, not to hear a separate TS9 sound. If the result becomes nasal, reduce the TS9 Tone or use less midrange on the following pedal.
The RAT 2 also stacks well, especially after a low-gain overdrive. Placing a clean boost or TS9 before the RAT increases saturation and sustain; placing an EQ or overdrive after it can restore definition. Stacking two high-gain pedals at maximum settings usually adds noise and compression faster than it adds useful volume.

A practical setup method
Set the amplifier clean or at the amount of breakup you normally use. Put the pedal’s gain at about one-third, tone or filter at noon, and level at unity volume—the same loudness on and off. Play both open chords and palm-muted low notes. Adjust EQ only after the gain is useful.
Next, test at rehearsal volume rather than bedroom volume. If the sound is harsh, reduce treble or use more mids. If chords blur, lower gain before changing the EQ. If the pedal disappears in a band, add mids or reduce bass instead of simply increasing volume.
Final recommendation
Choose the ProCo RAT 2 for the best all-round distortion range. Choose the Boss DS-1 for inexpensive classic rock, the Ibanez TS9 for tightening an amp, the Boss MT-2 for adjustable high gain, and the Nano Big Muff Pi for sustaining fuzz-rock textures. Your amplifier’s existing sound should make the final decision: bright amps often prefer the RAT’s filtering or a TS9 used sparingly, while darker clean amps can benefit from the DS-1’s sharper attack.
