Micro-Booster is a linear booster that offers unparalleld tone clarity and signal performance. Although it is powered at 9V, internaly it operates at more than 30 volts (rail-to-rail). Even under the most demanding signal conditions and gains, it preserves complete signal clarity.

Thanks to its specifications, Micro-Booster is suitable for a vast range of applications: guitar, bass, keyboards, line and instrument levels. It can directly drive power amplifiers preserving the signal integrity even when long cables are used for the connection.

Micro Boost

The micro-Thumpinator is a bandwidth optimizer designed for bass guitar. It removes the low frequency signals that are outside the range of notes produced by the instrument.

Infrasonic frequencies cannot be reproduced by standard bass cabinets but they often make amplifiers clip, especially when they are set to boost the lower frequencies. The Thumpinator filters the signal content optimising the energy delivered by the amplifier. Low-frequency clip is substantially reduced and the sound is tighter especially at high volume levels.

The micro-Thumpinator accepts instrument and line level signals. It can be used between preamplifier and amplifier, between bass and amplifier or anywhere in the effect chain (line or instrument level). It can also be connected directly to an audio interface.

micro-Thumpinator v2

Der Sfx Sound micro-Thumpinator v1 ist ein dediziertes Hochpassfilter-Pedal, das für E-Bass entwickelt wurde. Seine Hauptfunktion ist das Entfernen von unerwünschten, unhörbaren Unterschallfrequenzen, die bei Verstärkern zu Clipping führen und den Sound, besonders bei hohen Lautstärken, undifferenziert machen können. Durch das Herausfiltern von Frequenzen unter einer bestimmten Schwelle strafft es den Low-End-Bereich, verbessert die Klarheit und optimiert die vom Verstärker gelieferte Energie. Das Pedal funktioniert mit Instrumenten- und Line-Pegel-Signalen und kann an jeder Stelle in der Signalkette platziert werden.

Bandwidth OptimiThe Sfx Sound micro-Thumpinator v1 is a dedicated high-pass filter pedal designed for bass guitar. Its primary function is to remove unwanted, inaudible subsonic frequencies that can cause amplifiers to clip and sound muddy, particularly at high volumes. By filtering out frequencies below a certain threshold, it tightens the low-end, improves clarity, and optimizes the energy delivered by the amplifier. The pedal works with both instrument and line-level signals and can be placed anywhere in the signal chain.zer: Cutting off fundamental frequencies below 30 Hz
