Yeah, I owned one of the original Dan Armstrongs ages ago, after my 63 EBO.
It was sort of like a very heavy, see thru EBO.....except my Dan Armstrong happened to be fretless and had an original black pickguard...none of the fake brown wood grain on it. All original though.
I recall not really liking the sound. Not at all warm like an EBO. had all the warmth of lucite
It was ages ago but for some reason I recall the neck being kind of like if Ibanez made a Gibson EBO copy.
I'm not purist...have owned aluminum neck Kramers and liked them and also a metal upright...but the lucite looked much better than the bass sounded or played.
For the life of me, I cannot recall how I got that bass. Probably in a trade, since I would not have bought a fretless back then. Back then I didn't realize how rare the non-brown woodgrain Dan Armstrongs were or else I might have held onto it. Used it briefly with my progrock band back then because the violin player also had a clear violin and a matching Dan Armstrong 6-string.
Even stranger was how I got rid of it.....traded it to a local bassist in one of the bigger local bands when I was in college. I advertised it in a local classified....and he showed up in his van, which he was LIVING IN!! he didn't have any cash but traded me a SUNN 2000S head for the Ampeg....and that head became my amp for the next 10 years!! Sold it briefly because of the weight and then bought another because I couldn't get my sound with the lighter solid state A.M.P. And SWR heads I tried.
Many know that SUNN 2000S bottoms are VERY rare. Well, this same bass player had the matching 2000S bottom in his van and, despite being broke and living in the van, absolutely would not sell me that bottom. Pretty funny, looking back on it.
