Vintage Synthesizers

TR-808

Most of my synthesizers are old, of the 70s and 80s variety. In fact, I barely have any new pieces of equipment. This isn’t because new synthesizers aren’t any good. There are plenty of great, brand new synthesizers that can either do things that old synths cannot, or else they can do the same thing as old synths (but just much more reliably). So that begs the question: why have old equipment? My answer has always been simple albeit a little unsatisfying: I just like old synthesizers.

I also like old computers. My stockpile of old computers is thankfully nowhere as extensive as my synths, but I’ve definitely got a soft spot for those old computers from the 80s. Part of it, I’m sure, is nostalgia. I picked up an Epson Equity 286 computer not long ago, because that’s the only computer we had through my entire childhood. I’ve got the granddaddy of all IBM compatible computers: the IBM 5150. I bought it because I thought it looked really nice (it’s built to cold-war nuclear shelter specs) and because of its place in computer history.

In general, I like old things. I’ve always just assumed it was a matter of asthetics or nostalgia for the past. For $100, you can buy a software version of the Arp 2600 which sounds, to my ears, identical to the $6000 original. Or you can get the DOSBox emulator for free and relive the experience of computing in 1984 without all the pains of keeping aging and flaky computer hardware running. At times I’ve asked myself if I’m simply being snobbish or elitist by clinging to the authentic originals.

Recently I was reading an old interview with John Chowning that Keyboard magazine did back in the late 1970s. The timing of the article couldn’t have been more intriguing. Chowning describes FM synthesis, but this is well before Yamaha made it into the mega hit of the 80s with their DX-7 synthesizer. To Chowning, FM synthesis was just one among a great stormcloud of impending digital developments that were about to upturn the world of electronic music. Chowning talked exciting about all sort of other soon-to-emerge concepts. He talked about the ability to use tunings other than the traditional western 12-tone system without the phase dissonnance that often came with experimentation in alternate tunings. He talked about being able to have unprecedented control over tonality and timbre. He was excited about what computers would soon be doing for music. In short, he seemed giddy with anticipation for what the next few years of technology would bring to the world of music.

That same exuberant optimism is also prevalent throughout older computer literature. People marveled at the ability to balance their checkbook with Visicalc. Writers couldn’t contain their enthusiasm for word processors. Umerto Eco spent the whole first chapter of ”Foucault’s Pendulum” oozing on and on about the glories of backspacing and saving files.

I like old computers and old synthesizers because it reminds me to appreciate the utter opulence of our technology-saturated lives. We are technological royalty, having been gifted with unthinkable power. I take it all entirely for granted. I forget how precious these things would have been to someone 10 years ago, or shocking to someone 20 years ago, or unimaginable to someone 30 years ago. I’m reminded that someone in 1982 would have paid dearly for what I can casually do today.

To really cover all my bases here, Jesus told the parable about the stewards who were entrusted in varying sums of money. The famous moral sums up “to whom much is given, much is expected.” Not that I see any underlying moral virtue in using old gear, but I like to be confronted with just how much we have been given these days. Using old equipment helps me remember that. I like to be reminded of how painful and limiting technology was just a few short years ago.

Orphan Studio Pic

Studio

 

I had some old rolls of film laying around and I finally got them developed today. Flipping through the pictures, I noticed one or two photos of all the synthesizers. I must have taken this a couple years ago, judging from the synths and the layout. Probably interesting only to me and boring to the other 7.091 billion people in the world.

Years ago I was looking at old family photos (approximately my diaper era) and saw a rather mundane photo of the kitchen. It looked like an accidental photo, since there was no one in it, but I could see the sink and refrigerator in the background. I stared at that refrigerator for a long time, almost in a trance, realizing that I had some very dusty and vague memories of it. Little brain cells that had been asleep for 25 years were finally sparking again. A refrigerator is a boring thing, but as a baby I must have paid that thing a lot of attention.

I realized in that moment that sometimes the most interesting pictures (and I’m speaking personally here, not as a matter of photographic composition/aesthetics) seem in the moment to be the most mundane. I likewise cherish the one or two photos that I’ve found of my very first car. So every once in a while, I take a picture of all my studio equipment. Then I forgot about it and stumble across it several years later and I marvel at how things change.

The Last Project

I picked up an old Arp Odyssey recently.

Arp Odyssey

It was one of those snap eBay purchases – a synth listed just moments before with a Buy-It-Now price that seemed unusually low. I’ve made a lot of those types of purchases in the last couple years. It all started with an Oberheim OB-1 that I got for $300 (plus the seller wound up throwing in a semi-functional SH-101 for free). I’m not a gambling man (or at least casinos and lottery tickets don’t really phase me), but the thrill of that split-moment decision became a little addictive.

I began watching eBay listings in most of my spare moments. I bookmarked the page of newly-listed analog synths and made a habit of routinely checking it. I’d check in the grocery aisle, on the L, at a stop light, or during breakfast. Checking at a rate of about a dozen times a day, a good deal seemed to show up every two to three months. Sometimes I was a little trigger-happy and wound up with a purchase I wished I could take back. But once I got a TB-303 for $150. That was certainly the high point, heartily nudging out the OB-1 snag from its gloried throne. I’ve bought two Minimoogs, a Matrix 12, an AKG C414, a Roland RS-09, a TR-808 and probably a few other odds-and-ends using the same technique.

Sometimes the items are in pretty-much perfect shape (like the 303 or 808). But most of the time, there’s a lot of repair work needed. The two Minimoogs required re-bushing the keyboard, heavy cleaning, some moderate electronics repair work and, for one of them, a new wooden case. The OB-1 had some filter issues but, more alarmingly, actually had a piece of the case sawn off. I ultimately had to find a local welder who specialized in aluminum welding. The Odyssey falls into this later category of synths. It’s in sad shape. Like the Minimoogs, the uneven keys are a tell-tale sign of needing new rubber bushings. A couple of the sliders are snapped off. The case seems to be missing all but one lonely screw. I believe it powers on but I think the seller claimed that it “makes funny sounds”. For an analog synth, that could mean anything from “totally broken” to “works like usual”. For the price, it’s probably still worth all the work. But lately, repairing broken down gear feels like all I do anymore.

This blog is actually a nice illustration of how I feel at the moment. I started it out in that great blog tradition of just wanting to meander about the subject and share what I’ve been up to. I thought I’d perhaps post semi-completed songs or talk about what excites me about certain pieces of music. Instead, the blog has veered deeply into the subject of my latest gear acquisition, and how I’m in the midst of repairing it.

So I’m trying to take a step back from repairing synths. And more broadly, from buying synths. And perhaps even getting rid of some synths. I suppose that calling the Odyssey “the last project” was a bit melodramatic. I still have a number of items that I intend to fix up (I’m looking at you, Lexicon Prime Time). But I’m trying really hard to stop this behavior of gear acquisition. At least for a little while.

Bit One Mission Successful

I’ve had a broken Crumar Bit One synth sitting around for about a year now. This last week I finally got it fixed up and it’s already on its way out the door (courtesy of eBay).

Crumar Bit One

I bought this from a guy in Chicago last summer. I was heading to Chicago for an old roommate’s wedding and I noticed the synth on Craigslist. I emailed the guy and we started trying to figure out the logistics of meeting up. Apparently I mentioned that I was in Michigan and he immediately grew very cautious and said that the synth likely wasn’t worth driving down to Chicago solely to see and that it had a few problems. I told him I was heading that way anyway and left a little early to make a slight synth detour.

Everything was fine, but occasionally a note would sound sort of weird. The seller wasn’t a keyboard player and wasn’t really sure what was going on. I noticed that this was only happening to every sixth note, and it sounded like the filter simply wasn’t being applied. The Crumar uses Curtis chips for its filters, so I hoped that maybe one of the chips was just bad. I figured out which Curtis chip was tied to the faulty voice and tried swapping in another chip but the problem remained. At that point I got busy with other stuff and the synth sat around all winter. Resolving to finish it up, last week I got it back out and opened it up.

Bit One - Workbench

I don’t have an electronics background and I feel like I’m over my head whenever I start poking around at the circuits. But I’ve watched my friends Kris and Jon (both gentlemen who have a much stronger grasp on electronics theory) troubleshoot circuits and I’ve gleaned that sometimes it’s better to just try to follow your gut, and swap parts out for a true empirical test. I think I’ve erred on wanting to conclusively prove that a resistor or diode was bad before I replaced it. Sometimes it’s better to just have a hunch and then test out that hunch. So in this case, I started measuring voltages around the Curtis chips and found that the voltages coming out of a couple op-amps were far different than all the others. I’ve seen old 70s vintage op-amps fail a couple times in other synths, so these seemed like worthy suspects. A quick trip to Radio Shack and I had two new op-amps installed.

Sure enough, that fixed the filter issue. Apparently one or both of these guys were bad:

The Culprits

I cleaned up a few more little things on the synth and then listed in on eBay. It’s a cool synth and I like it. But these days I’m trying to focus on using my Matrix 12. I’ve trying to narrow my focus a little, so I need to thin out the herd a little. Hopefully this will find a new happy home somewhere!
