Is a SVT-3 Pro a upgrade to the SVT 350/B2R?

    I know its a tube preamp and only 150 watts more punchier but, I was wondering if in terms of volume and tone if it was a better amp that the SVT-350/B2R?

    Here is the thing I can dump 180 in getting my SVT-350/B2R and GK Backline 115 out of the pawn shop.

    Or I can buy a used SVT-3 Pro for $500 bucks. 500-180 = 320. So I am wondering if it is worth the upgrade for 100 extra watts and a tube pre-amp.

    Of course it's an upgrade! ;) The 350 was designed to lure non-Ampeg lovers to the fold while the 3 Pro was designed for folks who love Ampeg tube amps but were willing to sacrifice some tube glory but not all.

    3Pro is a big upgrade. It's as close as you're going to get without power tubes.

    The 350 is not that desirable and the Backline cab is an entry level cab. Go for the 3-Pro.

    Didn't notice the cab part so yeah, a 3pro and a better speaker is going to be a night and day difference.

    Ya, the Backline is a crap cab. GK makes some nice cabs. The Backline series ain't it. If you cheap out on anything, cheap out on the head or bass, never the cab.

    FWIW, we used to get those svt350's as backline from time to time. I guess because they were cheap and still kind of "looked the part"? I don't know but just don't use those to judge what an Ampeg can do to your sound. Most all of their other amps are way better, and not just by a little bit, more like they were made by a completely different company.

    3Pro is a great amp. Great all around gigging mans head and one of the best DI outs you will ever use. Tone for days through FOH....!!!

    Great I am glad to hear this. What I will have to do is just cut my losses with the SVT-350 and just put that $180 towards the Ampeg SVT-3 Pro...and then just save up for a decent cab. I think patience will be pay off in the long run.

    The Backline, GLX are more beginner cabs and serve a purpose but not when you start getting serious about playing ;)

    Yes, definitely a solid step up, but I'd consider a 7 pro before a 3 pro nowadays. Maybe even the PFs.

    IMO a used 3Pro should be $350-$400 tops, and it better be mint without issues at that price.

    Here you go from our TB classifieds: http://www.talkbass.com/forum/f127/ampeg-svt-3-pro-super-deal-1018600/?highlight=ampeg+pro

    Pay attention to any type of noise on startup or shutdown as it could be tubes or MOSFET bias issues. I'm absolutely NOT saying they all have issues, just mentioning it as I tried to buy an older 90's SLM used model and it had a noticeable decaying noise on shutdown. Come to find out the power section had an issue that was leaking voltage (or something) which was supposedly expensive to fix.

    I thought it was a great sounding amp.

    I wouldn't buy a USED 7 Pro period.

    Get one of the later versions. It was the early ones that had QC issues...

    I don't think it was QC issues as much as design issues they have been working on. Class D is new to Ampeg/LOUD Tech.

    Ok I'll chime in here..Played a 3 pro for 15 years without a problem until I spilled a beer on it then POOF, BAM!! Great amps! Lots of flexibility in tone.

    There is the bias procedure for the 3pro either linked to or explained somewhere on this site. It is not a difficult process if you have just a very basic knowledge of messing with electronics....meaning figuring out where the test points are, reading a meter and turning a screw. I'd much rather do that than take my chances with anything but the very latest revisions of a 7pro or pf500...and maybe not even those.

    The 3pro is a good old leadsled. Been rocking for 20 years and made to be maintained so it rocks 20 more. It's not some smps, smt, d, thing built by the lowest bidding robot.;)

    Yeah I thought about the PF-500 but I am not sure because I hear there is a lot of hit and miss with its reliability.
