The KSR Amps Eros- Slime Splatter is a limited-edition finish of the Eros, the company's boost plus EQ pedal. KSR describes the Eros as a "Modern Boost+EQ" and says it is one of the very few pedals that turns any tube amplifier into what the maker calls a fire breathing metal monster, super responsive and mouldable for modern metal tones1. It is not a simple clean volume push: KSR says it is not your typical boost, and that it will boost clean without overdrive, add a little grit, or add distortion, with a 3-band active EQ on top1.
The Slime Splatter finish
The Slime Splatter version is the standard Eros circuit in a different enclosure: matte black with a textured slime overlay1. KSR sold it as a Deal of the Week at $199.00 USD against the $280.00 USD list price, and the pedal is now archived on the maker's site1. The regular version of the pedal remains available as the KSR Eros Boost + EQ.
The Slime Splatter Eros is a limited edition that has sold out. KSR lists it in its Archive and SOLD -- Deal of the Week categories, so the standard Eros is the version to look at for current availability1.
Controls and switches
The Eros carries five knobs and two three-position switches1:
| Control | What it does |
|---|---|
| Gain | Sets the amount of gain the pedal applies |
| Bass | Low band of the 3-band active EQ |
| Mid | Mid band of the 3-band active EQ |
| Treble | High band of the 3-band active EQ |
| Level | Sets the pedal's output level |
| Mode switch | Selects clean, dirt or clip |
| Feel switch | Selects tight, fat or thick |
The Mode switch is what separates the Eros from a one-trick boost: clean boosts without overdrive, dirt adds a little grit, and clip adds distortion1. The Feel switch shapes the response between tight, fat and thick1.
KSR is explicit that the Eros should not be set up like a Tube Screamer style pedal. The maker's page says this is not "just another TS style boost," and gives a starting point of Gain and Level at noon, warning that the Mode and Feel switches lose effectiveness the lower the Gain control is set1. Players coming from overdrive or distortion pedals used to a hot output level will want to start differently here.
Power
The Eros runs on DC 9V with an internal booster, drawing at least 100 mA, on a center negative connector1. KSR recommends a 9V, center negative, 500 mA compatible power supply, which is not included with the pedal1. The current draw rules out some low-output daisy chain supplies, so a dedicated supply with headroom is the safe pairing.
Using the Eros with the Ceres
KSR positions the Eros as a partner to its Ceres pedal: the maker says to use it before or after the Ceres for even more control over its tones, and in order to get the most out of it1. Placed before, it shapes what the Ceres receives; placed after, it refines the Ceres output with the active EQ. For more on where a boost sits in a chain, see Boost Pedals.
Questions
What is the difference between the Eros and the Eros Slime Splatter?
The Slime Splatter is a limited-edition finish of the standard Eros, which KSR Amps calls the Modern Boost+EQ. The circuit and controls are the same; the difference is the enclosure, which is matte black with a textured slime overlay. The Slime Splatter version was sold as a Deal of the Week and is now archived, while the standard Eros remains the regular version of the pedal.
Is the KSR Eros a Tube Screamer style boost?
No. KSR Amps says directly that the Eros is not just another TS style boost and should not be set up the way a Tube Screamer style pedal would be, for example by cranking the Level. It is a boost with a 3-band active EQ that can boost clean without overdrive, add a little grit, or add distortion. KSR also notes that the Mode and Feel switches lose effectiveness the lower the Gain control is set.
Does the KSR Eros run on a battery?
The Eros runs on DC 9V power with an internal booster drawing at least 100 mA, and KSR Amps points to a 9V, center negative, 500 mA compatible power supply. A power supply is not included with the pedal, and the maker's page gives no battery option, so plan on using a dedicated supply rather than a battery.
Can the Eros be used with the KSR Ceres?
Yes. KSR Amps says the Eros can be used before or after the Ceres for even more control over its tones, and in order to get the most out of it. The two pedals are designed to work together in a chain, with the Eros shaping what the Ceres receives or refining what comes out of it.
What do the Mode and Feel switches do on the Eros?
The Eros has two three-position switches alongside its knobs. The Mode switch selects clean, dirt or clip, which sets whether the pedal boosts clean without overdrive, adds a little grit, or adds distortion. The Feel switch selects tight, fat or thick, shaping the character of the low end and the overall response. KSR notes both switches lose effectiveness the lower the Gain control is set.
