Last but not least the stereo output of the Looper goes into two of this devices. The Palmer PAN 01 is a D.I. Box that processes unbalanced signals into balanced ones. So I have two balanced XLR outputs wich get panned hard left/right. This creates a balanced nice stereo output for the final mix. Remember this is a passive D.I. Box because I have active pick ups. If you are using passive pick up systems you should better buy active D.I. Boxes.
The Vox 810 Valvetone is a pretty old-school overdrive pedal. Again only the magnetic pick up signal goes through this device. It has a warm, kinda crunchy tone and I use it for solos or to create a wide spectrum of sounds when I play flageolets. Unfortunately that pedal is retired years ago but you can still find some online.
The BOSS OC-3 is the most boring but also the most reliable base player ever! The signal of the magnetic pick up that goes through the tuner first goes into this device after that. Thanks to the poly mode it only adds an octave to the range you settled up before. In my case I only use it for the lowest string. That means I can play single notes and chords and only the lowest string will have an additional octave below the actual note.
This device, the Mi-Si Acoustic Duo is a magnetic pick up. The advantage of a magnetic pick up, like this one is, is that it only amplifies the strings. So theoretically this device allows my acoustic guitar to use FX that are normally more functional with an E-Guitar. For instance a distortion, octaver etc. work way more accurate and defined through magnetic pick ups compared to proper mics or under saddle pick ups. Also tuning through this device works more accurate and defined.
