Heads up Builders widely report inconsistent quality from PCB Guitar Mania boards, and whether a given board works is a gamble. Read recent forum reports before ordering.
From the vendor
Project overview
The Blender is based on an original design called The Phantom Pain audio router. Which, in turn, used the audio pathway of Earthquaker Devicesʼs Disaster Transport Sr. Delay pedal with a “modular” circuit that makes it possible to incorporate any three effects of your choice.
Introduction
Let’s see how this creative invention works:
Send/return A is always in parallel with send/return B. Send/return C is still in series with effect B.
The Blend knob lets effect A stay parallel with effects B and C, mixes the parallel A and B into effect C, or allows a combination of series and parallels.
The original author suggests that it might be worth trying to have switching jacks for send/return B and wire them up so that when there is nothing plugged into the jacks, the send goes directly to the return pad. Though he hasn’t tested himself, it could be a good option if you feel like trying because this modification would create a standard series/parallel pedal with two effects.
If you plan to make this a standalone, modular pedal, you might need to use a 1590BB due to all the jacks you need (2 for each send/return and 2 for the in and out).
