I’m having the exact same problem.

In my scenario I am using Input 1 to record a vocal using a microphone. In Input 2 I am using an aux send from my desk to route synthesizers for looping.

I turn the Input 1 to OFF, but given they are gain pots and not volume pots, the vocal is always heard when the dry out fader is up.

This also means that with the Input 1 pot set fully OFF, it will also always be recorded, i.e. in mono mode it will record the synthesizer with a vocal bleed.

I send the 45000 to a delay in my pedal chain, which I use quite hard, so I don’t want a bleed of vocal constantly coming from the pedal. I can use the Dry Out fader to turn off the dry signal, but this also turns off the signal from Input 2 so then I don’t have any synthesizers being routed through.

This would be resolved if the gain pots were volume pots, and gave full control over the inputs. Could it be possible to mod this unit so that the Inputs do control the input fully and have the ability to turn the input off, rather than just controlling a bit of gain? I would be very interested in this modification if it is offered… I’m currently considering returning the pedal.

It’s a very odd design – why would you add input knobs and have them not fully control the inputs?? Confusing.

I have found a small workaround which is to run the 45000 in the stereo mode, but only use the left output jack. That way I can use the pan on the Dry Out which effectively becomes the volume control I need, so I can turn it off to not have it in the mix while Input 2 is. The negative of this is I can only run this pedal in mono plus I always have to record in stereo mode with the loop faders 1 and 3 turned down… so I only really get 2 channels of loop rather than 4… unless I want to loop vocal bleed.

Any suggestions with my scenario would be appreciated. God I wish the input control knobs could actually fully control the inputs…
