Zero Loss FX in 1959/2203 2in1
Posted: Fri Jul 06, 2018 4:42 pm
Hi all. I just installed the Metro fx loop in my 1987/2204 switchable amp, and while everything works perfectly when in 1987 mode, I am having issues on the 2203 side. When the loop gets engaged, I get a slight reduction in volume, drastic loss of treble, as well as a diminished response from the effects in the loop. Sort of like a heavy blanket was thrown over the cabinet. When I turn the loop off on the 2203 side, it returns to normal.
I wired it up as if it were a 2204 model when following the Metro fx install instructions. Meaning, I tapped the signal between the treble pot middle lug and the master vol pot). All voltage readings were spot on, no issues whatsoever during the install.
Has anyone installed the loop successfully in a 2in1? Is the issue because the amp shares a master volume (dual pot)? Thanks for any help!
