Bakers Double Neck - Bass and Guitar for Practice

I bought this way back when, just as a freakish novelty, without thinking much...
But it held up over the years so I was compelled to come up with a useful application for it.

It's a four string bass and a six string guitar combined so I thought it would be fun for solo practice -
accompanying myself with a fitting bass line while strumming and noodeling.

Nothing high - end on this one, so I decided EMG HZ - pickups would be "sufficient".

Now the instrument has a single mono output with a blend knob between bass and guitar.
First I thought about converting it to stereo, maybe two separate output jacks?
In the end I decided to split the signal after it leaves the instrument.

Again I (ab)use a simple passive looper as an A/B switch.
I have to say I was extremely lucky to get away with this solution without humming or buzzing issues, otherwise I would have to use a proper A/B pedal instead.

The coily cable from the Instrument goes into the looper pedal.
One loop directs the signal to the upper Digitech Jam Man which allows me to record a bass line and play it back trough my bass amp.
Then I can switch over to the other Jam Man and record guitar parts, feeding just the guitar signal to my guitar amp.
(The little tuner is connected to the second loop of the pedal btw).

What else to say - it works for me and it's way more fun than to just play to generic backing tracks.
