The H24 is a steep high-pass filter pedal by Sine Effect Electronics.

This filter pedal has an adjustable frequency of 25-400Hz, and a slope of 24dB/octave (4th-order).

This pedal is ideal for electric bassists and guitarists who wish to tighten up their low-end. The pedal outputs unity gain and is designed to be low-noise.

Review by Basschat

As requested by many musicians after the release of the H24 and L24 filter pedals (see my other listings), the C24 pedal combines the two and also allows a clean boost of up to +20dB.
Two adjustable 24dB/octave slopes will allow you to tighten up and boost your tone like nothing else you've heard before.

The nanoPara is a new 1-band parametric EQ pedal from Sine Effect Electronics. After many years of trying to fit the goods into a small 5x5cm box (1.97") - without any compromises - it has finally been accomplished!

The nanoPara is analogue, fully-parametric, True Bypass and low-noise. This pedal could be very useful for guitarists and bassists looking to adjust their tone without taking up much pedalboard space.

Die Wee D.I ist eine aktive D.I-Box mit geringem Rauschen, kompakter Größe und der Möglichkeit, entweder über +48V Phantomspeisung oder ein separates DC-Netzteil betrieben zu werden. Im Gegensatz zu passiven, preisgünstigen D.I-Boxen bietet dieses Pedal eine vollständige Frequenzwiedergabe von 10Hz bis 20KHz.

Das Wee D.I Pedal verwendet eine Neutrik-XLR-Buchse, Nichicon-Kondensatoren und einen modernen, rauscharme Operationsverstärker.

Die Masse in diesem Pedal ist dauerhaft über einen Widerstand und einen Kondensator getrennt, was die meisten Brummschleifenprobleme verringern sollte, während das Pedal korrekt funktioniert, wenn keine Schleife vorhanden ist. Die Phantomspeisung wird automatisch getrennt, wenn ein DC-Stecker eingesteckt wird.


The Wee D.I is an active D.I box with low noise, a small size and the ability to use either +48V phantom power or a standalone DC power supply. Unlike passive, inexpensive D.I boxes, this pedal has a full-spectrum frequency response from 10Hz to 20KHz.

The Wee D.I pedal uses a Neutrik XLR socket, Nichicon capacitors and a modern, low-noise op-amp.

The ground in this pedal is permanently lifted via. a resistor and a capacitor, which should mitigate the majority of ground loop issues while allowing the pedal to function correctly when there is no loop. Phantom power is automatically disconnected when a DC plug is inserted.

The X24 pedal splits up your signal between highs and lows with a steep, 24dB/octave slope (4th order), and allows you to pass them through other pedals to be mixed back together if needed.

A full-spectrum clean blend can also be mixed with the split signals.
