EQ/Reverb Foot Switch Prob. MarkIIb

[gatekeep]

Hello, I just got a vintage Boogie EQ/Reverb foot switch on ebay. I checked it out and it seems to be wired correctly(steiro 1/4" jack). I tried it out in both 1/4" inputs near the reverb tank inputs and the volume gets very low and the reverb stays on?
I'm wondering if the post effects level mod is some how interfering?
Thanks....

I'm not sure of the mod you talk about, but are you using a Y cable.? The sockets on the chassis are mono and the socket on the foot switch is stereo.
