    I have a couple of questions about the Ampeg SVT 3-Pro
    Looking to pair up with an Ampeg 410 (would love to get the Ampeg Pro Neo)
    Currently I am using an Ampeg B 410HE love it but may be the wrong paring.

    Also need to replace a few knobs (not sure where) and was wondering how I should go about asking for maintenance/service on the amp head. I'm not sure what to have the tech look at or work on as a basic service to keep it working well without getting fleeced. Tubes I may need and good price. Thanks in advance!

    Tubes you can easily replace yourself, but unless there's something wrong with the sound of your amp, there's no need to replace them. www.fliptops.net should carry the missing knobs. If not, you could call Ampeg and see if they can sell you some (they're in Woodinville, BTW). As for someone to work on it for you, Ampeg has a lookup on their website where you can find an authorized repair place. In Spokane, that shouldn't be hard to find. Amd your B410he should work fine with the 3 Pro.

    Thank you! Is their a standard maintenance I can or should do or have done?

    Not really. Other than occasional tube replacement, there's not much else you can do with it. But the tubes should only be replaced on a case-by-case basis, and if the amp is working, I would leave them in as long as you possibly can. Preamp tubes can last years and years sometimes.

    The only problem I have ever had with a 3 Pro is the bias adjustment drifting. You can tell the bias is off when the amp is making a fuzzy distortion sound. If you have this issue, a tech is required. Also, I recommend a four ohm cab with that amp if you have the option-it sounds a lot better at full power imo.

    I was thinking that as well. Is there a 410 4ohm Neo cab?

    Nope. But on the bright side, I used to have a 3 Pro and ran it with an 8 ohm cab and I thought it was great. It's still 275w, which is nothing to sneeze at.

    The cab I have is only 200watts. Is that a potential problem? It's the Ampeg B410 HE

    If you use your ears and the gray goop between them, it will be fine. Here's a helpful hint: if it sounds like it might explode, it will.

    FWIW, I used to own a 3PRO and loved it for many years. I'd consider picking one up again if the price was right.
    I'd have your tech look at the poweramp bias, test your tubes to see if any need replacing (they might be fine!), and do a general once-over for broken solder joints, bad pots, bad jacks, etc.

    I picked it up for $325. I checked it out inside looked good but dusty. They gave me a 6 month written warranty.

    I'm looking to get a 2x10 hlf and a 410 hlf. For less weight and versatility. I think the svt 3 pro should sound great.

    IIRC the 410HLF is a 4 ohm cab, so you would not be able to use those two cabinets together at the same time.

    He's referring to the Pro Neo 410hlf, which IS 8 ohms.

    So 8 ohm any two cab combo is fine. 4ohm only one cab. Is that the layman version or am I not getting it.

    I used the SVT 3 Pro for years and loved the tone. I swapped the tubes with EHX 12AX7's and got a bit more grit in doing so. My only complaint with that head was that it's lacking power. I was playing in a hard rock band with 2 guitarists but mainly large venues with good house PA's so it wasn't a major issue.

    Congrats on the score!
