Need advice! Existential crisis in progress! Kill one bass to save another?

First, hello all! I've been a reader on here for a while, but I can't remember if I've posted before. I hope this is a good place to ask this, but if it's not, a moderator is free to move it or ask me to move it. I'm honestly not much of a player any more, but I'm 47 and started when I was 16 and still enjoy picking up the basses once in a while.

Short version:

Is it wrong to disassemble and part out a perfectly good (and somewhat vintage) bass to restore another one that has sentimental value to you?

Long version:

Anyway, here's my situation. My first "real" bass was a candy apple red Peavey Dyna-Bass 5-string with black hardware. I LOVED that bass back when I was 17 (1988) or so, bought it brand new and actually had to order it since my local shop in my small town would have been crazy to stock one. I played it a lot, lots of bar gigs, weddings, stuff like that. Eventually (like 25+ years ago) , the active pre-amp went bad. When switched on, it would distort (fart) like crazy. I should have taken it in and had it repaired at the time, but I was super poor. So, to get by, I just removed the whole board, soldered the bridge pickup to a volume pot, and played like that for a while. The band I was in broke up shortly there after and I kinda retired out of it at the old age of 25. The bass was put in its case and forgotten about for many years.

A year or so ago, I saw a listing for a 4-string Dyna-bass of the same vintage pretty cheap on Craigslist. I was going to buy it with the intention of using it for parts to restore my 5-string (I also needed the knobs.) Turns out the one I bought also has a Kahler Bass Trem on it, which is pretty cool. I remember being a kid in the 80's and looking at the pictures in Peavey Monitor magazine and thinking it would be amazing. The bass is very very used, but still solid, everything works fine, it does need a good setup though.

So, here's my dilemma. I have begun to have second thoughts about gutting this bass. There's literally nothing wrong with it other than cosmetics. It feels wrong somehow, like killing someone for their organs. I definitely don't need it though, cool as it is.

The thing is, I know these basses aren't worth a lot of money, I figure in the condition it's in $200-300 TOPS, and that's probably being optimistic. However, the PARTS of the bass would easily be worth more than than. Used trems can go for nearly $300 alone. Completely disassembled, I'm certain the parts would be worth over $500, and that's after keeping the pre-amp and knobs. But I having difficultly getting past the fact that I'd be ruining a perfectly good instrument that someone else could play.

If I could just order the original replacement parts, I would do that and just sell this bass to make up the money. I love my old 5-string, but I'm not willing to go into a lot of money to fix it since I won't play it much. When I do play, I usually pick up my US Fender Jazz bass (that was a life long dream to own, I do love being an adult.) The Peavey pre-amp looks fairly simply (I still have it), maybe a guitar tech could just repair it? My solder skills are pretty weak, and my diagnostic skills even weaker, but I do have access to good shops, including Elderly Instruments in Lansing, in my area. I would prefer NOT to replace the pre-amp with something more modern, my goal is to make it all original, even though I know the original really wasn't that great.

If you've read all this, thanks! If you have advice, thanks for that too!

SO, am I a weirdo or what? :)

+1 to picking up a used onboard preamp. In fact, you’d probably be doing that for the new bass, even if you scavenged it. So, why make life complicated? Watch the TB classified and pick up a used quality onboard preamp. Worst you will have to do is enlarge the pot holes with a rat tail file. Lots of choices. I happen to like the Sadowsky and the Pope.

Edit: sorry, just read your pref to repair the old preamp. You could try that. The Elderly shop is great, and should be able to tell you if they could do that. Just be aware that could prove more expensive than just retrofitting one of the open market preamps. As to those open market preamps being “modern,” I’m not sure what to say. They’re just preamps. The Sadowsky has a thing called VTC, which rolls off most of what you would consider “modern.” The Pope is simply accurate.

By modern, I just mean a current not a period correct part. I guess I just want it to be back to original specs is all, like it was when I got it. I will think about a replacement if I can find one that has the same configuration though. The Dyna-bass of that period had one volume, a front-back blend knob, and a three band eq.

Alternative solution: swap the 4 string preamp and knobs to the 5 string, then wire up the 4 string as passive and use random speed knobs. Keep both basses.

Second alternative: swap the preamps, buy a Seymour Duncan preamp for the 4 string, keep both.

Third choice: swap the preamp to the 5 string, strip the 4 string of all parts and sell the parts. The bass will then live on in the 2-3 other basses it has brought back from the dead. Think of it as killing one bass for its organs to save many basses, not one for one.

I listed those options in my order of preference. Ie, I suggest the first one.

Back 20 years ago, you did check the battery first before ripping out the preamp, right? Because it sounds like it might have just had a dead battery. ;)

Well, I know I won't be keeping it in any case, but those are all good suggestions. As for the battery, I can only assume my much younger self would be smart enough to think of that. :woot:
 
At the moment, I'm thinking my best first choice would be to run my 5-string over to Elderly when I get the time and see what they say about repairing it. It could really just be a bad capacitor or something stupid. Once I get an estimate, I'll be in a better position to make a decision.

I'm curious, before tearing it out did you try a fresh 9v battery? Farting preamps happen when batteries die. Voltage sag and whatnot.

EDIT: Whoops, you already answered my question :D
 
The trem would be a useless gimmick in most cases. Scavenge what you need and sell the rest.

Or, yank the preamp for the 5, solder the pickups passive in the 4 (like you did before on the 5), put the factory knobs on the 5 and get afternarket ones for the 4.
