Can I use the AdrenaLinn III in the effects loop of my guitar amp?
Yes. AdrenaLinn III’s audio in and outputs process audio, whether inserted between your guitar and amp, in your amp’s effects loop, or inserted in your recording console’s signal path. The only difference is that the audio levels in your effects loop are sometimes a little higher, but the A3’s input and output levels are adjustable. Simply set the A3’s INPUT LEVEL control so that the CLIP light only goes on when you play very hard; and set A3’s VOLUME setting so that the volume is equal to the volume when the effects loop is not used. NOTE: Do not connect the power amp output (normally connected to a speaker) of your guitar amp to the input of A3. This is a MUCH higher level than the levels discussed above and will damage your A3.
