Members mbengs1 Posted January 15, 2020 Members Share Posted January 15, 2020 I was wondering if you connect a cabinet to a combo amp if you get the same tone as if the combo was converted into a head. Saw the amp's enclosure to the size of a head. Let's say a bugera 6262 2x12 combo connecting to a 4x12. is it the same tone you'd get as with a bugera 6262 head and a 4x12?

Members 1001gear Posted January 15, 2020 Members Share Posted January 15, 2020 If the impedance is the same, If you shut off the original speaker; should be close enough. Link to comment Share on other sites More sharing options...
Moderators daddymack Posted January 15, 2020 Moderators Share Posted January 15, 2020 well, there is more to it than that...closed back versus open back cabinet, and speaker efficiency, among other things, will certainly have an effect on how it will sound Link to comment Share on other sites More sharing options...
Members Grant Harding Posted January 15, 2020 Members Share Posted January 15, 2020 What do you think the differences might be? Same components and circuitry in slightly different shaped box. Can't believe I'm replying... Link to comment Share on other sites More sharing options...

Alas, no. He wants to know if the same amp in combo version sounds different to the head version when plugged into the same cabinet. Link to comment Share on other sites More sharing options...

If you want a head buy one. If you want to run your combo with an external cab do that. But don't butcher your amp. Link to comment Share on other sites More sharing options...

Members mbengs1 Posted January 18, 2020 Author Members Share Posted January 18, 2020 I know now. the cabinet knows if its a combo or a head that its connected to. Link to comment Share on other sites More sharing options...
Members 1001gear Posted January 18, 2020 Members Share Posted January 18, 2020 The tubes in a combo might be stiffer or braced better which could account for a difference between it and a head only. BUT if the units are identical, the speaker won't be able to reproduce any difference beyond the expected tolerance discrepancies. Link to comment Share on other sites More sharing options...

Sorry if this comes across as a personal attack but that's just patently silly. A cab has no brain, no awareness. It doesn't and can't "know" anything. An amp detects the electrical characteristics of a speaker; if you connect a second or extension cab in parallel the amp detects the change in impedance but that's not the same as "know"ing anything.

Moderators daddymack Posted January 19, 2020 Moderators Share Posted January 19, 2020 Bengs...do some reading, please. There are zillions of good books, videos, blogs on the electronic aspects of tube amps, speakers, Ohm's Law, and so on, and you will gain understanding of what happens from the moment your pick flicks a string and the sound comes out...it may a be a micro second, but there is an amazing series of events occurring to make that sound for you.

If you took say, a pair of Marshall amps that are available both as heads and as combo amps (IOW, the exact same amp circuit, except one is a head and one is a combo) and plugged both of them into identical 4x12 cabinets that are loaded with the exact same types of speakers, there will basically be zero difference in the sound of the two rigs. The speaker cabinet isn't impacted in the slightest by the size of the cabinet that the amplifier itself is mounted into - not if you're not using the speaker(s) in that combo. Quote Saw the amp's enclosure to the size of a head. Let's say a bugera 6262 2x12 combo connecting to a 4x12. is it the same tone you'd get as with a bugera 6262 head and a 4x12? Again, the tone will basically be the same, but you're destroying the value of your amp by sawing it up like that. Better to sell it and just buy / replace it with the head version instead. Or, you could have a new head cabinet for your existing amp built, and pull it out of the combo cabinet and mount it into the new head-sized cabinet. Heck, even a DIY head cabinet build would be a much better idea than sawing up a combo amp IMHO. Link to comment Share on other sites More sharing options...
Members 1001gear Posted January 21, 2020 Members Share Posted January 21, 2020 if the chassis (wtf is the plural of chassis?) and/or the component layouts differ, there's an audiophile chance the sounds will differ dramatically but you won't be able to prove it.

Members mbengs1 Posted February 11, 2020 Author Members Share Posted February 11, 2020 I tried plugging my marshall combo to my 4x12 cabinet and it didn't sound like a stack. It still sounds more 'combo-ish'. not like the heads, they really have backdrop that a combo can't dish. I wish I can get a nice amp coz my bugera isn't that toney. hehe.

Members 1001gear Posted February 11, 2020 Members Share Posted February 11, 2020 Did you disconnect the speaker? If there is a tonal difference they prolly have different parts. Link to comment Share on other sites More sharing options...

Singular or plural, it's still spelled chassis... the only thing that changes is the pronunciation: Pronounce chassis CHASS-ee (singular) and CHASS-eez (plural). Chassis comes from the Latin capsa, meaning box. Link to comment Share on other sites More sharing options...

Either that, or you just may not like the sound of your amp very much, and may equate a "stack sound" with a different amp circuit. Quote the cabinet knows if its a combo or a head that its connected to. Sorry, but no, it doesn't. The ONLY way that matters what enclosure and amp is mounted into is if you're using the internal speakers of the combo amp - then they're affected by the size, shape and construction of the enclosure. The amp itself is not impacted by those factors. Again, once you disconnect the internal speaker(s) and connect your amp to an external speaker cabinet, the size of the cabinet that the amp electronics are mounted in will have ZERO impact on the tone. It could be in a "head" sized chassis, it could be in a combo-sized chassis, heck, it could be pulled out of the chassis and sitting open on a tech's workbench (please do NOT try this at home! There are LETHAL voltages inside of a tube amp!) and it would not make any sonic difference. Link to comment Share on other sites More sharing options...
