My first bass was pretty much the Crestwood version of that Teisco. The Crestwood had the same body style, pickup and controls configuration. Mine had a lot more chrome though, the pickguard ran all the way down to include the volume ,tone controls and the cord input and it was all chrome. So were the pickup covers. The chrome content on that bass was on par with the chrome content of a 58 Oldsmobile and the weight was probably pretty close too
.
I bought mine used , but like new, with some POS amp for about $100 in 1966. I don't think it was a very good deal but it looked like brand spanking new and I thought the chrome was cool.
In conclusion, it was a turd. Unlike most turds, this was a turd that you could polish, and polish it I did, but it was still a turd. If my great powers of recollection and knowledge of turdology are still in tact, the Crestwoods of that era were a cut above the Teiscos. It would likely be a small cut above because it's pretty difficult to make a judgement call on quality when comparing one turd to another
