One Control Minimal Series White Loop

>Use
For recording studio.

>Connection
Input: Guitar to Chain of analog effects.
Green loop: class A Fender Tweed preamp + Modulation effects
Red loop: Diezel VH4 preamp + Modulation effects
Output: Mesa power amp + Palmer 2x12 Closed Back Cabin

>Facts
I have noticed that noise is being induced from Green to/from Red loops. I use an isolated 9 volt DC adaptor, as for each loop's chain of effects; none of the two extra 9V DC / OUT are being used. Still, ground, hum and hiss affect the Output signal.

>Test
Input: Guitar
Green Loop Send: none
Green Loop Return: out from chorus pedal with 9v batt
Red Loop Send-Return: sealed jumper cable
Output: Amp
Procedure: turn on the switch, set loop red (jumper), turn on the chorus pedal, listen to how the Amp captures the signal effect from the chrous pedal even while a different loop is being used. turn off the chorus pedal and unplugged it form the device. listen how the guitar signal is affected by the loop, even while using a jumper cable (buffer?).

If you have 2 parallel signal chains and want to switch between them in 1 click, this pedal is for you.

For example:
distortion1 -> delay1
distortion2 -> delay2

Now you connect the 1st chain as the 1st loop, the 2nd chain as the 2nd loop (send/return) into the pedal, and now you can switch between them! Also the processing can be bypassed. But I use this pedal to switch between 2 preamps that don't have bypass so they can't be connected in series.

The pedal looks just beautiful and due to white color it's easy to find it on a pedal board.

Also the switches are mechanical and of good quality. It also means the pedal can operate without voltage applied to it! 9V used to light up LEDs. It's really useful if you're out of power cords. Also the pedal offers 9V pass-through, which can be helpful too.

EDIT: when trying to loop high-gain distortion pedal the crosstalk between send and return, amplified by high gain dirstortion leads to feedback whistle. The pedal is unusable in this case.

Small loop switch pedal that is compact in size, and features that are perfect for looping pedals. I always have like 5-6 overdrive pedals, and instead of having signal to pass through all pedals, I now simply use this One control White loop to have 2 loops and in each loop 2 pedals.

In one loop I have Fulltone OCD v4 and Zendrive, and in second loop Xotic BB MB and EHX Soul Food. THis is when this pedals come handy - you can switch between 2 overdrives, depending on song, stack them together and have additional sound, and 2 switches are for changing loops and for true bypass.

Really handy tool, highly recomendable....
