Hey Flick, no worries, thanks for following up!

I ran a signal through my Left Input set the Dry Fader to full and plugged headphones into the Headphone Out. When I turned the pan pot from Left to Right it sounded pretty normal; when fully turned CCW sound came through Left earphone, turning towards 12 O’clock I got signal through both earphones and finally tuning fully CW I got signal through the Right earphone.

Using the Right Input instead and doing the same test I got the expected opposite signal routing: CCW went to Right, 12 O’clock to both, CW to Left.

Both sweeps were smooth.

Though there is bleed from either Input only the respective Input Pot will change the gain on that signal, in other words; if I plug a signal into the Left Input only the Left Input Pot affects the signal gain, Right Input Pot has no affect on gain. The opposite is also true.

Still, with each Input Pot set fully CCW signal passes through to the Output stage of the device.
While this bleed occurs the Dry Pot works as expected panning/blending/reversing stereo.

I just tried using the Left & Right Outputs respectively and got significantly less bleed but also less gain when adjusting the Input Pot.

Unity gain between the Left & Right Output (individually) and the Headphone Output occur with the Headphone Out Pot set at 9 O’clock.

In this context I’m using unity gain to refer to that of the Headphone Out and the Left/Right Mono Outputs , not of the signal actually coming in/out of the 45000.

I’m sorry if this response comes across as patronizing or repetitive at times; it’s not my intention. I’m just trying to be as thorough as possible to avoid unnecessary back and forth!

Thanks again Flick,
Aidan

Sorry, I should have been more clear; Dry pot is fully counter clockwise and I am still hearing both inputs.
I’ll reiterate that this happens even when input gain knobs are also fully counter clockwise. I obviously don’t know how the circuit works but it’s as if the signal is never fully shorted to ground.

I had considered turning the faders of the tracks down but as I understand it, each initial loop I record on the same track will essentially start to fade out as I layer on top of it; this doesn’t seem right.

In other words; if I record bass notes and higher pitch lines on the same track, for instance, the second line recorded will always be louder with this solution. Each new loop becomes the loudest as the older loops multiply by a lesser number and “fade out”.

Are there quick voltages/resistances I can check to confirm a failure?

Thanks Flick,
Aidan
