Any mod ideas (schematic attached)?

Post by johnnyvickk »

I have a univox 1221 and I was wondering if anyone could give me any suggestions on how to modify it to a more dumble sounding circuit. Thanks a tone. I have attached the schematic for this amp. Its a 100 watt 6l6 so I think it should be a good candidate.

Hi,
firstly, i know nothing about modding amps, I'm getting geared up for my first build.
I would think that unless they are very similar circuits to start with, distilling 'dumble tone' down to some mods wouldn't be possible. I've been reading the posts here for a couple months and it really is an all or nothing type of thing. guys spend alot of time getting actual dumble circuits to sound like dumbles!

but hey, line up the schematics and have a look.

A quick google puts them (univox 1221) in the marshall camp, my understanding of the dumbles is they are fender descendants.

Good luck.

I would love to try your amp just as it is sporting only volume and tone controls into reverb and tremolo circuits, nice.

Add the Dumble OD section and you could have a tweed ODS.

Are plans to strip out the existing circuits?

Take a look at Henry H's champ rebuilt and see how the OD is added.

Hey thank you guys for replying. Yeah the plan isn't to make it a dumble copy. I was just thinking of seeing if there was anything I could do to just add a little of that flavor, because from the research I have done, most dumble kind of amps are in the 50-100watt range with 6l6's driving the power amp, this is the same as this univox amp. So any ideas are welcome. I would also consider adding some circuts or something too.
