How to make a simple line level parallel effect loop? – Hardware (Instruments and Effects) Forum

I want something that I can use in the effect loop of a guitar amp or between a preamp and a power amp, which makes it possible to run a direct signal paralell to a signal with effects which can be mixed in with the direct signal as much as I want

There are several reasons for this. The most important is to avoid the decrease of dynamic response you get when using digital effects, another is the mixing of a dry signal with for example a wet signal using unusual EQ-settings or for example an IR-loader which distorts the signal. I have found the latter to make the result fuller and more interesting when used moderately. More subjectively I find parallel effect loops more controllable and better sounding
