vid of my Ampeg B-25B tube amp - for those of you who ask what the tube sound is like

Discussion in 'Amps and Cabs [BG]' started by throbbinnut, Jul 25, 2009.

  1. Here's a quick vid of one of my old Ampeg tube amps. Nothing fancy, and I'm no Les Claypool, but it gives a good idea of what tube amps sound like when pushed hard. Enjoy.

    Thnks, man. My favorite part was the critters running around. Second favorite part starts at about 3:00. Trippy.

    Maybe I'd enjoy that whole Ampeg tube head/big cab scene more than I thought ... Roadies first, tho

  4. Nope. I save all its strength for picking boogers.

  6. They just don't make them like they used to!

    You should think about using it more. You're cutting your options by 25%.

    The amp, I found, a little too mid heavy for my tastes but my B15 cabinet sounds much like that when I run it with my Hartke set flat. I didn't like the distortion at all. Back in the day that's pretty much how we all sounded if we got loud. I've spent my life getting rid of distortion so I'm more than a little biased. However to each his/her own.

  8. well, for starters, I would never use channel one unless I was playing a guitar.

    I just don't like it at all. I feel like I should, but I just think it sounds terrible. that breakup sounds like you threw your poor little kitty into the speaker :(

    not dissing your playing, just your amp. someone had to.

    You can't judge the tone on a recording made with a vid cam from 5 feet away. You get an approximation, but that's about it.

    I see where the others are coming from, people who are trying to get rid of distortion and whatnot...

    But as a bass player who's always trying to make usable distortion, that was pretty freakin rad. It made me real sad that I didn't buy an Ampeg SVT 3 Pro in a road case w/ a rack tuner that was on CL in my area for only $375 last week. Had my chance, oh well.
  11. an svt 3 is not going to sound like that, it's just not the same thing.

    and yeah, jimmy, I have a feeling that if I was feeling the amp bursting my gut I might think differently. I just don't think that distortion fits me at all. its almost too much, not enough clarity behind it.

    There's a lot more people who feel the way you do about it than those who like it, I'm finding out. I'll be honest...I can count on one hand the amount of gigs I do with distortion where I need it. I cut way back on my use of it since using effects again a year ago.

    After watching your video I have some questions for you though, how are you adjusting the sound? the face plate looks like it just has 2 sets of knobs (channel 1 and 2?) with 3 knobs each (bass, mid, treble?). Is there no master volume or gain? do you just adjust 3 bands individually to comprise the sound?

    I never said an SVT Pro would sound like a vintage all tube amp, all I said was that I missed a chance at a pretty good price on an amp that can produce a pretty nice amount of dirt.
  15. Yeah, there's only Volume, Bass, and Treble on the 2 channels. There's also Ultra Hi and Ultra Lo on each channel, but I never use those. On each channel I start off at about 10 o'clock on the volume (pretty much max clean volume), with Bass and Treble left flat at 12 o'clock. Then I turn the volume up to 12 o'clock to add distortion. On channel 2, when i start going for feedback, I actually turned it up to 1 o'clock. That's it. This amp was built in the days before master volumes were standard. You basically have to size the amp to the gig so that you're running right at the sweet spot for the sound you want. If it's not loud enough, then you break out a 100Watt tube head. :D


  16. You sound like my mom. You and her should hang out.

    Very nice. It's my current project - the B25B head and matching 2-15 cab. I've re-glued all of the lifting tolex, and fixed what needed to be, buffed out the rust on corners and handles and now I'm waiting on the rebuild of the second Altec 421A speaker to be finished. When I got the cab, it had Peavey Black Widows. BTW, I have 2 of these heads, a little newer one than the one that is original to the cab. From what I can see on your video, your head is the older one also. The differences on the front being the rocker switches for the ultra high and low are white on the newer one (black on the older) and the standby and on/off switches are toggle switches. :cool:
  18. Man, you are going to love the Altec 421A's. Best dang speakers ever made for bass, in my opinion. I have 3 of them that are all original and still sound great. I have 2 in a custom 2x15 box, and 1 in an old Peavey 1x15 box. Best sounding speaker I've ever heard.

    I dig it! I have just acquired a 69 B25 and am picking up a matching cab tomorrow morning. I picked up the head for $250 at a local vintage shop and the cab is a craigslist find. Right now the head is just sitting in the floor cause I have no cab here :(

    One thing about the recording that cant be determined is how loud it is I guess. I will find out tomorrow morning I suppose. Anyway, so channel 2 has more bass? Is there a significant difference between the two channels? I play mostly country and needed less than an SVT 8x10 but more than a B15. I figured a b25 with a 2X15 would be like having two B15's.

    Anyway, the cab has CTS's and is wired for 4ohms right now. Anyone know where a wiring diagram for hooking it up 16ohms is???

    I am really excited that I found a matching set for so cheap! It will amplify my '72 P with one year old Labella flats. Yummy!

    The tone you get towards the end of the video is amazing! Very Noel Redding'ish from some of the live recordings they put out.

    What model of Dimarzios do you have in your bass?
