Routing a guitar to 2 amplifier outputs
Overdrive / Harmonics
2 amplifer outputs
Made in Germany
Use two amplifiers with different sounds simultaneously with one guitar?
A mono-effect should be routed to a "wet" amplifier, a second amplifier should process the "dry" signal?
A stereo effect is to be distributed to 2 amplifiers?
ESTE I helps!
First, the guitar signal is routed through a compressor / overdrive / EQ section.
Afterwards it can be routed arbitrarily to 2 separate amplifier outputs. These are individually adjustable in volume.
In addition, an effect loop can be looped in, also in stereo.
The compressor works with a "smart" characteristic (microprocessor controlled) and is supported for weak input signals by a "boost" function.
The overdrive function is adjustable in the degree of distortion and mixing with the undistorted signal.
The active 4-band EQ offers a control range of +/- 12dB.
The two amp outputs are transformer coupled, ground loops are excluded.
The pedal provides both a true bypass (relay) and a buffered bypass. While the True Bypass guitar signal is directly connected to one of the amp outputs, the buffered bypass also includes the transformer coupling.
There is an additional tuner output, which is also operated by the bypass logic.
The switchable effect loop can be adjusted continuously between serial and parallel.
There are no operational amplifiers in the signal path! It is a fully discrete analog circuit with JFETs as active devices.
The supply voltage, supplied externally from a 9-18V power supply, is internally boosted to 24V for optimal dynamic range.
The overdrive section is designed to be "moderate", providing only extra harmonics and always supporting the basic sound of the connected instrument.
The individual JFET amplifier stages additionally enrich the overtone spectrum.
The basic character of the instrument is in the foreground, ESTE I supports and expands this if necessary and provides the comfort of 2 independent amplifier outputs.
