Amps...Amps...Amps...too much to choose from

I would go buy the Bandmaster.  Great amp and very versatile, and it loves pedals.  The price sounds reasonable.  He would probably take less if you take cash along.  I have a 1965 Bandmaster and it is my favorite amp.  Paired with the right speaker cab they are hard to beat.

The vintage modern has great cleans, as does the JVM series. The JCM2000's clean is really good as well. A  30th Anniversary model would sound great clean too. Actually Plexis and 800s have pretty decent clean tones as well, even though they're not known for that, but they're not Fender type cleans, as in "sparkly", that's all... If you need great clean and great dirty, your best bet in a Marshall would be a JVM...

Grab the Bandmaster!

The AC15 should be plenty to play a gig! 15 Tube Watts, right?

    Buy a Shure Microphone and a good Mic Cable. Costs less, and does what you'd need, allows you to run the Vox through a P.A. And the P.A. will give you all the volume you'll need.

   And your Vox WILL get good Cleans for Jazz, too.

    However, if you're just wanting a new Amp (and don't we all?  ), a Peavey Classic 30 or 50 would be a great choice. As well as any Fender Amp.

    Yes Marshalls get good Cleans too. But, the Bandmaster would be a GREAT choice. Plus, it will INCREASE in value over time. So, you should be able to get your $$$ back, easily.

    And again: 15 Watts is PLENTY for gigging. And much more manageable around the house.

    People who think you NEED more Wattage are probably relatively new to gigging. In fact, this is why peopleuse P.A.s in the first place! 
   Rookies often have this dream of getting a "Marshall1/2 Stack". Then, after a year or so of never being able to play them at the proper volumes, they finally give up and sell them for a huge loss of $$$. Andtheygo out and buy a 15 or 30 Watter that is actually useable. In fact, I make a good amount of cash each year buying those"almost new" 1/2 Stacks and re-selling them in the paper!

    Good luck on whatever you decide. None of it is life-or-death, andI'm sure you'll enjoy whatever you end up with.

Both are solid Amps. But,you're going to have to play them yourself to seeif they're a good fit for you.

    I think the Traynor is more versatile. And it would work well for you. Some people RAVE about the DeltaBlues.

    Both Amps use EL-84 Power Tubes, just like your Vox does. So, they will have that compressed, focused Midrange that gives Voxes a lot of their Mojo. Also, they break up into OD very well.

    However, you may prefer the bigger Frequency Range of 6L6 Tubes. Like a Twin Reverb uses.

    6V6 Tubes, like on a Deluxe Reverb are also great for your purposes. In fact, a DRRI is a great, CLASSIC Amp. It's been the choice of Gigging Blues AND Jazz Players sincethe originals came out.
   
    Again, nowadays Wattage isn't as much a factor as many claim.

    A Mic and a Mic Cable will go a long way..........

Little "Mountain Time" there....sweet.

If you are drifting into jazz, DO check out the Roland Jazz Chorus amps. They are as clean as you will ever get, and the stereo chorus is awesome. The only downside is that they are kind of high wattage for small spaces - my brother-in-law never had his 120 turned up past 2 when gigging in Philadelphia.

I eventually sold my JC77 because I am headed the other way and I wanted a darker smokier sound which I now get from my Egnater rebel 30.
