TC Electronic Spark Mini
Clean boost (mini form factor) · Up to +20dB clean boost, single Level control, true bypass, mini pedal form factor$40–$60 new / $30–$45 usedBest for: Compact clean boost, simple solo level boost, pedalboard space saving, affordable starting point
The TC Electronic Spark Mini is the most affordable compact clean boost — a single Level control provides up to 20dB of transparent volume boost in the smallest possible form factor. The Spark Mini sits on the pedalboard without taking up space, and true bypass ensures it adds nothing to the signal path when disengaged. For players who want a simple volume boost for solos or to push a tube amp harder, the Spark Mini is the uncomplicated solution. Used at $30–$45.
What to check used: The Spark Mini is a clean volume boost only — it adds gain uniformly without affecting tone. Players who want tone-shaping or treble boost character should look at the Xotic EP Booster or EQD Arrows. The Spark Mini is purely transparent.
#2
Xotic EP Booster
Echoplex preamp booster (subtle tone enhancement) · Echoplex EP-3 preamp circuit, up to +20dB, internal DIP switch for tone adjustment, mini form factor$90–$110 new / $65–$85 usedBest for: Sought-after Echoplex preamp tone, subtle warmth and presence enhancement, always-on boost
The Xotic EP Booster replicates the preamp stage of the Maestro Echoplex EP-3 tape delay — a preamp that players like Jimmy Page and Eddie Van Halen ran their guitars through (as an always-on tone enhancer) even when not using the echo. The EP Booster adds subtle harmonic richness, warmth, and presence without obvious coloration. Unlike a clean boost, the EP Booster adds character. Internal DIP switches adjust the amount of treble and presence boost. It is the most popular always-on boost pedal. Used at $65–$85.
What to check used: The Xotic EP Booster is not entirely transparent — it adds the characteristic Echoplex warmth to the signal. Players who want completely transparent volume increase should use the Spark Mini. The EP Booster's coloration is the point; it makes single-coils sound slightly fuller and humbuckers more present.
#3
Earthquaker Devices Arrows
Treble boost (preamp boost) · Preamp-style treble boost, 30dB range, discrete transistor circuit, single Level knob$80–$100 new / $55–$75 usedBest for: Classic treble boost tone (Rangemaster-style), pushing amp into natural overdrive, British rock tone
The EQD Arrows is a treble booster — the circuit type originally used by Eric Clapton and Tony Iommi with Marshall amps in the late 1960s. A treble booster emphasizes upper frequencies while boosting overall level, pushing a tube amp's input stage into natural harmonic overdrive. The result is the classic British rock tone that defined the sound of Cream and the early Black Sabbath. The Arrows delivers this in a modern compact package. Used at $55–$75.
What to check used: Treble boosters work best with medium-to-high gain tube amps — they increase the treble frequency emphasis, which can sound harsh through a clean amp or solid-state. The Arrows is not a clean boost; it adds treble character. Placement: treble boosters are typically placed at the beginning of the signal chain, directly into the amp input.
#4
MXR CAE MC-404
Dual buffer and boost · Buffer circuit + clean boost, two independent stages, vintage buffer design, true bypass option$100–$130 new / $70–$95 usedBest for: Buffer + boost in one unit, preserving high-frequency content with long cable runs, transparent boost
The MXR CAE MC-404 is the professional buffer and boost combination — a buffer prevents signal degradation (loss of high frequencies and signal strength) across long cable runs or large pedalboards, and the boost provides clean gain for solos or amp pushing. Players who run long cable runs from guitar to pedals to amp, or who have large pedalboards with multiple true-bypass pedals, benefit from a buffer at the beginning of the chain. The MC-404 provides both functions in one pedal. Used at $70–$95.
What to check used: Buffers are most useful in systems with long cable runs (over 20 feet) or large numbers of true-bypass pedals (which load the signal path cumulatively). In simple setups (short cable, few pedals), a buffer adds minimal improvement. Assess whether your signal chain actually needs buffering before investing.
#5
Analogman Beano Boost
Dallas Rangemaster-style treble boost · Germanium transistor treble boost (original Dallas Rangemaster circuit), Level knob, choice of transistor$140–$180 new / $100–$140 usedBest for: Authentic germanium Rangemaster treble boost, Eric Clapton and Mayall-era tone, boutique build
The Analogman Beano Boost is the most faithful reproduction of the Dallas Rangemaster Treble Booster — the silicon/germanium treble boost that Eric Clapton used on 'Bluesbreakers with Eric Clapton' (the Beano album) to drive his Marshall combo into natural overdrive. Analogman builds these with selected NOS germanium transistors for authentic vintage character. For players who specifically want the original Rangemaster circuit quality rather than a modern interpretation, the Beano Boost is the professional choice. Used at $100–$140.
What to check used: The Beano Boost is a specialist boutique pedal — its value is specifically the authentic germanium Rangemaster circuit. Players who want a general treble boost should start with the EQD Arrows. The Beano Boost is for players who specifically know they want the Rangemaster character.
#6
Wampler dB+
Clean boost with buffer · Up to +20dB clean boost, buffer circuit, internal voltage doubler for more headroom, true bypass$90–$110 new / $65–$85 usedBest for: Transparent clean boost with buffer, studio-quality headroom, Wampler build quality
The Wampler dB+ is the premium transparent clean boost — a clean boost with an internal voltage doubler that increases headroom for transparent operation. Wampler is known for boutique-quality construction and the dB+ follows that standard. The buffer circuit can be engaged or bypassed via internal switch. For players who want a completely transparent volume boost with no tonal coloration and premium build quality, the dB+ is the choice. Used at $65–$85.
What to check used: The Wampler dB+ does add subtle character at high boost levels despite being described as 'clean' — at maximum boost with a tube amp, some harmonic enhancement is audible. This is typical of all boost pedals at extreme settings; the dB+ is among the most transparent at moderate settings.
#7
Keeley Katana
Boost with tone control · Up to +30dB clean boost, Tone knob for bass/treble balance, two gain voices via internal switch$90–$110 new / $65–$85 usedBest for: Clean boost with tone shaping, +30dB for really pushing tube amps, Keeley quality
The Keeley Katana provides up to +30dB boost — more headroom than most boost pedals — with a Tone control for adjusting the bass/treble balance of the boosted signal. At maximum boost, the Katana pushes tube amp inputs into significant natural overdrive. The Tone control allows compensating for EQ changes that occur when pushing an amp hard. For players who want maximum boost with tone-shaping capability, the Katana is the premium option. Used at $65–$85.
What to check used: 30dB is an extreme amount of boost — at maximum settings with a high-gain amp, the Katana produces significant distortion. Typically used at 9-15dB for solo level boost or amp pushing. Ensure the signal chain can handle the input level at high boost settings without other pedals being overloaded.
