Need advice for Selmer Treble n' bass 50 mk 2

[trev09]

Hi everyone,
I need some good advice. My father's Selmer Treble n' bass 50 mk 2 has come to life again, after decades of sleep. Thanks to a man with golden fingers. Now I want to use it ! So here are two questions :

- which cab would most fit with this vintage head for bass use ? Budget and light weight are required ;-)

- I read that the head can be jumped to get a richer sound. How to do that ? What type of jack, in which plugs ?

Thanks again for your coming answers !

AFAIK the amp has two channels and each channel has two input jacks. I believe one of the inputs on each channel is padded a bit.

Jumping the inputs usually means running a short patch cable from the second output of one channel to the input of the other channel. The jumper is basically a short instrument cable, I.E shielded cable with 1/4 TS connectors. Try all of the combinations and choose the option you think best.

Alternately you can get a mono ABY cable. Plug Y into the bass, run A to channel 1 and b to channel 2. It's pretty much the same as the jumper option above.

If you want to play at a higher volume you need an efficient cab. If you want to be able to push the output tubes into distortion at a relatively low volume, then you can choose a less efficient cab. For explanation: See my posts in this thread:

Would like to hear recommendations on pairing newer type cabinets with the 100t. The amp is from 2014. My preference is small, maybe multiple high performance lite weight cabs. To old to handle 6-10 etc. i have on hand Epifani Dist 3 1-12 & 2-10 and Bergantino NRV 1-12. The Epifanis are for sale as well. I am not tied to these cabs mote interested in "best" fit. Genre is Blues old, texas, modern. Not hard rock, metal, punk etc.
Thanks Pedro

Hey mate, any chance you've found a nice cab to pair with your Treble & Bass?

Do you mean the second *input* ? If memory serves me right the only outputs on those amps were to the speakers, and connecting one of those to the other input channel would not make for a happy day.

You definitely don't want to connect the speaker output to an input.

We are talking about jumping channels. The second input on a channel become the first output.

Into Normal channel (black). Thru normal channel (red). Link from normal channel to bass channel (blue). Signal path for normal channel (orange). Signal path for bass channel green. Combined normal and bass channel to output (purple). (signal paths are simplified)

Experiment to see which works best.
You can go into the bass channel and loop thru to the normal channel.
You can also go into input 2 on a channel and out on input 1. AFAIK this won't matter in this particular amp.
