Title: Do We Like This Effects Loop?
Post by: blown240 on November 04, 2011, 11:39:33 pm
I found this online and added the DPDT bypass switch.  Is this a good schematic?

Looks like I can switch between parallel and series, and the DPDT I added will get me a true bypass.  I can tell if there is a blend knob for clean/colored on the paralled side.

Thoughts?

There are maybe a dozen or  more FX loop schematics in ARCHIVES that you can compare this with.

That looks very much like the London Power loop. It's a good loop and is very transparent.
