New Ampeg Amp DAY!!!

Brown santa delivered my 1969 blue line Ampeg B25!



I want to give a huge thanks to ddbassGA. It is as amazing as he said! And packed the best i have ever seen!

Well i was floored with this amp! Spent about 30 mins playing. This is the first amp i have ever rolled the bass back on. This thing is BUDDA. By far the best sounding amp in my collection! And yes that includes my SB-12! I didnt run her to hard but man it thumped thru my Kustom tuck and roll 2x15!

So any setting suggestions?

Cool info about B25?

Tips and suggestions?

More pics.

Thanks. It's been a pleasure to get to know you too!


Also found that i had the ultra low switch on. That is why i was backing down the bass knob:rollno:

Also you turn that ultra low off and wow it gets louder faster.

I have alot to learn about this one. Any one have a link to a owners manuel?

Also what is the electrical outlet on the back for?

The piggy back thing is plugging your bass in one channel, then running a little jumper, like people use on pedals, or another regular guitar cord will work too if you don't have a short one, from the 2nd input on the channel your bass is plugged into, to one of the inputs one the other channel. Usually makes them sound thicker....and you then have more knobs to play with, 2 volumes, 2 basses, 2 trebles, etc.

Note the two inputs for each channel on this are attenuated differently. The Normal inputs are good for standard passive basses. The "Bright" inputs, as far as I could tell are just attenuated inputs that lower the input. Would be good for active basses today, even though they didn't have active basses in 1969.

You rock, Fuzz! Great score...looks like it's in pretty good shape, too. Yeah, glad to see you kids respecting the vintage tube amp thing...does my heart good to see you enjoying them so much. Hope you two have fun together!

Ch 1 sounded more trebley to me too. Sounded like Keef Richards on Brown Sugar with my Tele. I liked Ch 2 with my '69 Precision. Oh dang. I meant to get a picture of those 2 together before I sent it. Please send it back.

Dummy speaker plug already included. :)

Which brings me to this: why would they make 16 ohm the default output for this head? (and the orig cab). Just makes no sense to me.

Thank you for playing "What were they thinking in Linden after Jess left."

Back when it came out, interchangeability wasn't as prized as it is now. Separate amps and cabs were still a relatively new concept, too. But you can trick the B25 to run at 8 ohms by sticking a blank plug into one of the speaker outs, and tube amps take lower impedances much better than higher impedances, so all is not lost.

+1 to the interchangeability thing. People bought rigs back then... not amps and speaker cabs. Seems like 16 ohms was also way more common back then. My old Hiwatt has 4,8, and 16 ohm taps. Modern updates of that amp, like Reeves have 2,8, and 4.
