    Well... I'm not the first, but I just made my own!

    Two years ago, I had an idea of making a guitar play bass lines at the same time so I can jam with my son who was learning to play drums at the time. It was boring jamming without a bass player. I came up with a rough first version of it early last year. I'm not really an electronic person but through another forum friend'st ech advice, we have come up with a 2nd and final version.

    I now call the guitar, "Gemini".

    Bass sound is on the left channel, guitar is on right channel.


    The guitar is a Yamaha EG112C2.

    It has 2 circuits. The first circuit is for the normal guitar with its own volume pot. It has no tone control and goes to the output jack. It has a GM Railbucker bridge and a Fleor single coil sized rail humbucker with 5-way switching. The second circuit is for the middle pickup which was replaced with a 2-pole pickup that only picks up the 5th and 6th strings. It also has its own volume pot with no tone control and also goes to its own output jack. The signal is being fed to a Digitech Drop to convert it to a lower octave sound to simulate a bass.

    Gear used:
    Boss GT-100 for guitar effects
    Digitech Drop as octave pedal
    Behringer BDI21 Bass Amp Modeler
    Behringer UMC204HD interface

    DAW: Audacity

    It has crappy tuners right now. I would like to change it in the future. I am looking at changing the nut also.

    Hmm, I'll look into it. What are you listening it through? It's fine on my studio monitors.

    After posting my first video demo above, I had requests to make another demo isolating the bass sound. So, here we go! Enjoy!

    Back in 1968 there was a guy you've probably never heard of called Chet Atkins released and album on RCA
    made with a custom Gretsch guitar that had the low E & A strings from a bass guitar and the rest from a standard
    guitar. The album was named Solo Flights.

    My understanding (which may be wrong) is the guitar had stereo pickups that fed some strings to one channel and the rest to the other channel. I dunno how that worked out in the final mix.

    I do not think Gretsch ever sold that model guitar.






    Here's what Chet's guitar tech had to say about it some years ago:

    ___________________________________________________



    You have to use D’Addario short scale bass strings, 080 for the 5th and 0.100 for the 6th

    It's not easy to do this because you have to have a bridge that you can hook the bass string to as they are a lot larger than a guitar string.

    . Chet and I had two guitars that I fixed up… one a Country Gentleman with the Schaller “finger” tailpiece and the other was a Tennesseean with a stop tailpiece.

    You then have to file out large notches in the saddles for the strings and also enlarge the notches in the nut. Then you need to drill out the holes in the tuning keys posts so the bass strings will go through. It's not easy to set the intonations on the two bass strings. Then you have to raise the action pretty high on the bass side for it to work. It's quite an undertaking and if you aren't going to use it very much it's not worth all the time to do it.

    Paul Yandell
