I get emails from Elderly Instruments in Lansing Michigan. They have a guitar which I built a while ago. Here’s a screen dump of a part of the listing.
You can find more information about the instrument at the link below.
This was the first guitar with 8 strings I made. April 1997 according to my records. It’s been a long time since I’ve seen this guitar. It looks to be in pretty good condition. I cannot resist noting this elderly instrument (25 years old) is at Elderly Instruments. !
But the action looks perfect, the finish looks good. The top shows some playing wear, but there is thin golpeador on the top that protects it.
Zachary here, I just purchased your 8 string from Elderly! I was wanting to ask what brand of strings you would recommend. I should be receiving shipment today! Very excited.
Congratulations, and I share some excitement.
In general I trust D’Addario.
The exact strings? It sort of depends upon how you want to tune it. I often individual base strings from D’Addario. Maybe NYL050 and NYL052 or 054 would get you to have a low D and Low C,B or A.
I had one customer who had an high E as the 8th!
Any 6 string set you prefer should work.
