Hi BassBuzz! I have this 5-string Ibanez BTB Premium for a few years now that I found used in a Maryland Guitar Center in 2018. I never really cared to find out details about it until recently. To my shame, I found out that I can’t even tell what the exact model of the bass is! Here are some pictures of the bass:
The easy answer here would be to say that this is an Ibanez BTB1935 or a BTB1835, but the thing is that the top of this bass’ body is not the one that Ibanez constructs them with, and the switches are both 2-way; there is NO three - way switch like the electronics diagram for the 1835 AND 1935 suggest (link).
The serial on the bass is J0551E. The only site where I’ve had some answers when I look up this serial is this site, where if I put in J0051E it finds a production year of 2014 and another “serial” of 0551. Premium Line, Indoniesia.
I even made a small YT video where I play the bass and fiddle with its electronics to try to get answers from the Internet. I’m really weirded out by this, not even sure what the electronics do, or whether they are well - configured.
Controls consist of a global volume; balancer; individual bass, mid and treble EQ controls; a EQ bypass toggle; and a mid-frequency switch to select a 250Hz or 600Hz.
Thanks so much guys! I see that the model, when introduced by Ibanez, had Nordstrands. Mine has a pair of Bartolinis, but hell knows what kind of model they are Again, I got this fellow used and only started caring to find his origins 4 years after the purchase
