I messed myself over (Warning: Long post with Ampeg content)

Boy, I sure blew it. Had me a nice little Markbass combo that did everything I needed and sounded great for its size. Bring it and a bass and a cable to a gig and you're out of there like a trumpet player at the end of the night. But that wasn't good enough for me. I had to completely overhaul my 69 SVT that had been sitting dormant for over 10 years. It took over a year but it finally looks like it's fixed for good. So I just had to take it to my gig tonight...

Bought it in 87, I think, for $650. Organist Doug Ingle of Iron Butterfly owned it and ran it ragged. All the speakers were shot in it, and I never had enough money to get it restored properly, so even though it sounded great to me, I never really heard it at its full potential. But last year I decided to have it restored. I knew it was a very early SVT, but I soon found out it was one of the very first SVT's ever made. So I spared no expense to get it up to technical speed. Had all the CTS speakers reconed. Had the head completely overhauled and a really stupid repair by an incompetent tech undone. All the tubes were replaced with NOS tubes (power tubes are 6146B's), and every single cap was replaced, solder joints were all redone, and now I imagine it works just as it did in 69. I didn't redo any tolex so it still looks like crap, but I did throw a cheap grillcloth on it and bought a few new knobs.

Sounded great at home so I took it to my gig tonight to see how it would perform after all these years. I don't get emotional over my tones, but I honest to God never heard an SVT that sounded as good as this one. It made playing an absolute joy like I haven't felt for a long time. I thought my B-15 stack was an amazing amp, but never in my life have I played an amp this good. I was a little louder than normal but nowhere near what it's capable of, and every note popped out plain as day with tons of cojones.

Took me a little while to find the sweet spot, though. I started in channel 2 because it sounded the most B-15-like, but I went to channel 1 in the middle of the second set because it had more bottom. But when you set channel 1 flat, it sounds more like a 70's B-15 with the Thiele cab, and there's not much upper mid or high end to speak of in those Thiele cabs. A little trial and error brought the treble knob to almost 1:00, and that brought back the proper amount of attack and somehow brought a tad more upper mid out of it, too. Yeah, that's the sound! And that cab...man, if you never heard a straightback 810 loaded with freshly reconed and broken-in CTS's, then you have never heard an SVT, my friend! I'm sorry, but no cab on earth compares.

So how did I mess myself over? I'll tell you how...as heavy as it is, I don't think I can ever use another amp again. Tonight was the first night I ever heard this amp playing up to its full potential, and as good as everything else I own is, nothing else even comes close on a gig. Love the B-15's but this SVT is in a class by itself. And yeah, it probably weighs close to 250 lbs. total. But you know, it really wasn't nearly as horrible a load as I thought it would be. There were a couple deadlifts I could have done without, but setup and teardown was only slightly longer with the SVT. And if you use leverage, getting the cab up and down off the stage really isn't so bad. I'm sure I'll have some load-ins I'll desperately wish I had the B-15 for in the future, but I think I'm going to have to suck it up and just do it.

I also messed myself up by not restoring it a long time ago. I started to once, but abandoned the idea because of lack of money, and by the time it broke for good, I just decided the weight was too much to handle and the cost too high for a broke musician. But had I known I owned the holy grail of SVT's, I would have never gotten tired of lifting it. The way I felt after the gig, I could have torn it down and set it up somewhere else and kept on playing a few hours more.

And you know how everyone says on here that your rig only matters to you? Don't you believe it! I got compliments on the sound from the civilians in the crowd like I never got before. Turns out many of them actually do notice the sound of the bass. Could they have been listening with their eyes? Maybe, but the end result was the same so what do I care? ;)

So now I've gone full circle from my beginnings and I'm back on the SVT bandwagon once again. It may look like hell, and it may weigh a ton, but it's a rare SVT like few have ever experienced, so I will lose weight and get back in shape so I can keep moving it on all these one-nighters I do :bassist:

I didn't get to take any pics of it on the gig tonight, but here's a pic of the head right before I started the repair work. Doesn't look much different now:

Hahaha, man you had me for a second! I thought you blew up your SVT or something :)

Great story! Makes me wanna get a third 8x10, but a straight back this time. Gotta have one for comparison.
 
I don't know when the cab was made, honestly. I thought it was original with the head, but the speakers are from 1973. The cab label gives the address as Linden, NJ, so it could be from any time between 69 and 73. And serial numbers in that period are no help for dating it.
 
Dude, that thing looks like it would knock you down with awesomeness... A Berg NV610 and one of those would be teh secks.
I could go for a 65 lb. weight reduction. And all the SVT experts say the NV610 is the closest thing out there to a straightback 810. But I have a straightback 810 already, a wife who thinks I have a ridiculous amount of gear already (she's right BTW), and the NV is $1200. But don't worry Trev...it's very much teh secks as it is :D :bassist:
 
Awesome story! Congratz with your restored SVT!

I bought a 'blue line' stack over a year ago since I wanted to own the holy grail. And because I still live with my parents and don't have to pay rent or what so ever I could effort one. (over here in Europe those f*ckers cost a lot!) But I can tell ya... it was and still is worth every penny!

At this point I don't play it a lot since I play in a hardcore/punk band and we only play for like 20 minutes which means warming up and cooling down the amp lasts longer then our set does.

Here you see my ex on the left which is a SVT-VR with a 810AV. And next to it you see my new darling.

Wow first time I saw a current 810 and an old straightback side by side. This explains more about why I don't like newer 810's as much as the old ones. The new one's 2 or 3 inches taller. Between the cheap speakers that handle tons of wattage but sacrifice clarity, and the larger cab, no wonder they all sound woofy to me. I can make them work, but I always have to roll off low end, which I don't like to do because it takes away from what the head brings.

Your 69 looks great, BTW. Much better condition than mine. I can't restore the tolex on the head because of the stencil, but I plan on restoring the cab as soon as I can recover from all the money I spent on restoring the working parts.

Does your vintage head have 6146 power tubes or has it been changed to the 6550's? Have you ever tried the VR in the 69 cab? If so, how do they compare?
 
They changed it to 6550's before I bought it. So I can't tell what sounds better. Is it possible to change is back and does it make it any sense at all?

The picture above was taken only minutes before the VR got picked up by the new owner so I wasn't able to compare them.

By the way.. what type of fan is in your SVT? Mine got replaced by a new one which is way to noisy.
 
cool Jimmy! i'm glad that you took it to the gig. they are meant to be played. i love my SVT's too (always have) and they've never let me down. once they're loaded in and set up, its really nice to not have to even think about getting a great tone, and when that happens, it inspires me to play my best.

as far as weight goes, i knew when i got my first one in '74, that i'd just have to get used to dragging one to and from gigs from then on.
 
Sure, it's possible to change it back to 6146's. I don't know what's involved with it but I don't think there's much to it. Most techs don't recommend changing it back once you've done the mod, though. It's not especially cheap to do (6146's can be found pretty easily NOS...they're way cheaper than 6550's but still $25-30 a tube in the US), and there's supposed to be something a little shaky about the way 6146's operate that make the 6550 a more suitable tube for the job. Tonally I couldn't tell you the differences because I haven't got to AB it against one with 6550's, but my tech thinks it has more power than most SVT's with 6550's. But 6550 SVT's sound fantastic, too, so if I owned it, I'd at least wait till the 6550's blew before I changed it over, if I did it at all.

I have no idea what the fan is, but I'm almost positive it's original. A little noisy, but doesn't bother me.

John, I really don't know what I was thinking by not using it for the past 11 years. These past few months got better because I at least used a B-15, but I pretty much feel like I sold my sound quality down the river using a hybrid and a 410 for 10 years. Almost like I cheated the audience. So I'll be making up for lost time now, and I'll do the schlep happily until my poor tired body just can't take it anymore.
 
before i got it, my '69 was a 6146B amp. it had already been converted to 6550's and since i have quite a few GE6550A's on hand, i just left it that way. i've had a 6146B model in the past, but without having it here to compare them, i couldn't really say which i like better. but to me, all of them sound great .
 
Jimmy, thats so inspireing to hear.
My tech says mine will be in my hands by Monday.
He says it's putting out a solid 320 watts.
He's also a bass player and owns 6 SVT heads.(calls them his kids collage fund)He owns both 6146 heads and 6550 heads and says by far the 6146's just are magic!
As far as the flat back cabs go, I used mine with my sons 350H head and it made THAT head sound fantastic.
Those cabs really are part of the magic that is SVT.

Jimmy, great story, I told you before that you were spoiled by the sound of the SVT. I've also said that the rigs we use matter to us more than the audience "in general." If I take my B15-N to a gig, a couple of people will tell me it's a great vintage amp, a couple will tell me they have never seen an amp like that and the majority of the crowd will only know the bass makes that low sound.

I can hardly lift the SVT on the 810, but I still believe that if I haul it around, it's more for my listening pleasure than the crowd. Just my opinion.
 
great story Jimmy. It goes to show that classic things are classic for a reason.....they stand the test of time.

I never mind seeing Ampeg get some love....classic stuff...I own some and I still have friends there. I was just talking to Dino on the phone the other day.

:bassist:
 
Hey Jimmy, i thought you were gonna say you ended up messing your pants onstage!! :eek: :D

Several years ago, Jimmy Cliff came to the melody tent here at Cape Cod. Both bands bassists played thru an older SVT, and the sound was awesome!! Like rolling thunder, but clarity all the way around at the same time.
 
Nice! I will totally agree that there is nothing else that sounds like the original SVT rig. If that's your thing, it's unique and wonderful.

Thank god it's not my thing. That is a ball buster rig to haul around!
