My amp is a Framus cobra head and it has a horribly picky parallel effects loop. I'm looking for a Delay (digital preferable) that works with at Line Level with Parallel Effects Loop. It needs a killdry to function properly (I think). I have the MXR carbon copy deluxe (analog) and I love the sound but it has noticable volume drop when it engages. (both in loop and in front of amp). I'm seriously thinking of getting rid of the amp & cabinet and moving to Line 6 Helix.. maybe you guys can help!
