I have rented a Yamaha Silent bass for the month while my bass is in the shop. I'm playing it in a pit orchestra setting and a little solo work and while not inspired by the sound of the Yamaha, the practicality (and affordability) of an EUB is attractive.
My upright is a 60s Kay S9, which were pretty much top-line Kays new. It's quite beat up and the problem with it currently is that the fingerboard is coming unglued. But it's got a great jazz tone and, with the Strings I have on it, a decent arco tone.
I worry that if I invest in a carved bass I will a) stop playing my Kay entirely, which I would see as a shame, or b) Play the Kay for jazz gigs and the carved top for legit gigs, but not play enough settings that I would not be able to get away with arco on the Kay.
I should say that I'm not a fan of selling my instruments. Dad sold a 59' American strat in 1980 so he could afford these cool new things called "Squier"s
Would it be worthwhile to get my Kay in tip top shape, and think about looking into EUBs like ergo or NS to consider as a second bass?
