Ampeg B-40

[Louis-Carl]

Hey everyone..

New here and also new to Bass playing I'm late to the party starting my playing career at 44 but it is what it is..

To the point.. I bought fairly cheap I hope do this setup to start . Any information people can give me on the Amp would be appreciated. The bass is a standard beginner Yamaha.. Amp is from what I can see an Ampeg B-40 combo from 1973...if I believe my buddy who sold it to me . Said he did some research with the serial number and all .

Sounds great but is it any good

Thanks in advance

Ever get answers?

Wouldn’t be 73, they didn’t release these until 1975. The B410 and B115 combo amps were available earlier in the 70s but the split head/cab were later.

I’ve had two of the cabs, the first was a 77 with kind of light duty eminence speakers, the second was a 75 with the same CTS speakers as my flatback 8x10. Worked well with my V4 and other heads.

Same as coreyfyfe I had a 75 B40 cab that I used with a V4B. Later moved up to the SVT810 but the cab sounded great IMO.

Keep it!

Here are the schematics and specs.

OK, you wrote it sounds great but "is it any good"...well, you already know the answer to that. It survived 40 years of use in one piece, so it's reliable. The 120 watts rating is probably more honest than ratings on some modern amps and the with that cab it's going to be plenty loud.

Hey you somehow sneaked by me! Welcome to TalkBass!!!

I had the cab a while back. I completely refurbed it.

The short answer is, if it sounds good to you, it's good!
