Unless you are very lucky, whatever driver you pick is unlikely to work at it's best in your combo's cabinet. This is especially true for use with a bass. You could quite possibly damage the replacement.

Not too many full tube amps came with a DI. What would the use be of bypassing all the tasty goodness of the output stage and it's interaction with the speaker cabinet? A microphone captures all that and more. The cost of such a microphone would be less than all these cabinet simulation pedals. You might as well plug the bass right into the PA.

Thing is that why simulate when you have the real thing on stage. A good microphone puts out everything you need in real life. you have spent a deal of money on your sound system to get it to sound as you want it to.. Why cut that out of your stage show?

Stick a good microphone in front of the cabinet. You want to capture what the cabinet is adding to your sound. Plus you want to hear what the output tubes are bringing to the gig.

Thanks for the reply. We likes to hear how our advice helps our fellow bass players.

For me I left full tube amps behind in the early eighties. Even the 150W beast I built was insufficient to give me the clean bass at volume that I desired. I swapped from the beast to 200W per channel stereo power amp, again home grown, and finally I was happy. My current rig is a 2KW capable stereo Class D power amp driven by a tube pre-amp I designed for that purpose. That said I do love the tone my Sixties Ampeg B15NF gives me. :)😍

@sambecker1 You out there??

Enjoy your 'new' amp. Ampeg tube amps do seem to sound Wonderfull!

Put wheels on it and call it a wagon.

I have to admit I did like the drum kit - or lack of!!

Only if you want to destroy a perfectly good 15! A 15 can pair with a 2x10 reasonably well but anything else puts the 15 at serious risk of failure.

I changed all the speaker connectors I own over to SpeakOns many years ago. 1/4" Phone jacks are an accident waiting to happen IMHO.

Really the manual is as clear as mud. I have the feeling that the combo has a 4Ω minimum which is filled by the internal speaker. Then again the manual says 'short circuit proof power amp' so who knows. I would be very wary about connecting a speaker in parallel with the internal diver. That would mean a 2Ω load. Get it wrong and you have a blown amplifier. Incidentally most combo amplifiers develop their maximum power into the internal speaker.

So OP did this solve your problem??

Earl Preston's Reflections. I left the band late 1968 due to having to work outside the city. Met my wife in that band an June 06 1968. The name Earl Preston was his stage name real name George Spruce. He was a MerseyBeat personality.

I never learned to read music. In 1962 when I bought my first bass, I worked on a potato farm for the summer to get it, I was cramming to pass my GCEs. That done it was Engineer school and job pressures. There just wasn't time for everything. Anyhow I ended up in one of the top bands in Liverpool at the time. Still my second favourite band I ever played in. LOL

For me the perfect cabinet was the Acme B2 2x10 three way. I liked the first so much I bought a second. The pair stacked on their ends for a vertical 4x10 was the best I have ever used in my sixty odd years of playing. I was so impressed with them that I bought a second pair.

If this little trick works for you you can just leave a short signal cable, like those between effects pedals, permanently in that position.

Wot do you expect from a Canuck?? LOL

For laughs and giggles check out . The bass is a lined fretless six string that I had never played on stage before this. LOL I'm the little old fart on the right.

I found it wonderful to watch another six string player strut his stuff. Thank you for that!

Just for the purpose of education: there is no such word as omage unless you stick an H in front of it. The correct term is Impedance.

Bassman 50 cabinet - YUCK!

LOL

I never liked the cabinet myself. Playing through one was never a pleasure.
