Housing built to accommodate the level of an effects loop signal, in the sense that we want, that is, the booster or mitigate, to be able to adapt one or more effects pedals.
The boost part and the mitigation portion can be adjusted separately, and if desired can interchange the (for either boost or attenuate the signal and possibly bring it to the same level of output effects loop).
The case is powered via standard type Boss 9v power supply and consumes 50mA.
There is a small switch that removes ground loops.
Thanks to the mini switches can also decide to remove the effect of the boost and the attenuator to be aware of the impact of the case on sound reproduction.
You plug the send and return of the amp in a small metal box attached to the adapter, so it has only one cable that goes to the main housing levels adjustment. From there one branch in the "loop" of this case to include the pedals, it is in this "loop" that "boost-attenuation" signal is applied.
The setup is pretty simple. We must look at what level you want to boost the signal from the loop and adjust the corresponding attenuation (or reverse).
Moreover, nothing forces you to match boost and attenuation, you might decide, for example, mitigate and many little boost the signal but the overall output volume would be lower (or vice versa, and the volume is higher ) .dropoff window See for yourself.
I just see two kinks to use:
Boost and attenuation levels adjustment screws require a screwdriver .. We must stop playing, catching his screwdriver ... When seeking the setting is not very convenient. After once it is set so it is left over, so it's not a huge failure.
Second thing, for psychopaths accuracy: D, setting the levels are not serrated.
Effective and transparent perfectly, nothing to say.
Used in the effects loop (line level) of my amp.
Used for 1 month, I have no complaints is good stuff !!
With experience, yes I do it again this choice without hesitation.
However, I had to wait a long time for the chance to pick up a secondhand (even if the new price is not exaggerated).
