I have an Ibanez BTB400 series. Year unknown but it has the Ibanez (not Bartolini) pickups. I bought it off eBay about 3 1/2 years ago (I know... shoulda checked TB Classifieds first). After about a year of play the sweepable midrange pot crapped out. I am told by multiple sources that that is a proprietary Ibanez part that is virtually impossible to get... and after over 2 years of trying without success, I've had enough. The bass is unplayable in its current condition so I have been doing some research and these appear to be my options: 1) Replace everything but the pickups with an all-new aftermarket system (e.g., an Aguilar preamp and pots package for which I was quoted $215 + installation) 2) Replace only the faulty mid control using a fixed frequency boost/cut pot (similar to the current, stock bass and treble controls); this would run me the price of a pot ($5-10), + installation 3) Invest nothing more and try to sell the bass as-is. If I go with option 1, I will essentially be spending as much to fix the bass as I spent on it to begin with... and while I like the bass, I'm not in love with it. I don't want to be that guy who puts $3,000 worth of rims and rubber on a 73 Pinto but it kind of feels like I'd be doing that here. Going with this approach would almost obligate me to keep the bass because I would never get that investment back out of it on resale. Is a BTB a good enough bass to warrant that kind of additional investment? Option 2 would make the bass playable again at a fraction of the cost of option 1 -- albeit without part of its original functionality -- and then I could either keep it or sell it (and put that money towards another bass... possibly a G&L or something else closer to the Fender "family tree"); the question there is, would I have more trouble selling it (or have to offer it at a deep discount) because the sweepable mid no longer exists? Option 3 really doesn't sit well with me but potentially could be the easiest way out if I could find a buyer and were willing to take a major loss on the sale. Basically pawn in it off on the next owner (with disclosure, of course) and let him/her decide how to fix it. The problem with that option is that I would wind up practically giving it away so at the end of the day I'd be out the bass and have very little money to put towards a replacement either. What would you do?
