  • I have a wacky idea.

    Maybe I haven't thought this through properly, but this just came to me last night. I was reading the recent Guitar World interview with Adam Jones where he explains his preference for using a multiple amp set-up. In his case he uses a couple of Diezels and an old Marshall. Well, his main reasoning is that a single amp will not give you the full range of frequencies you're looking for. In order to get enough midrange, your highs and lows will suffer. In order to get enough bottom end, your midrange and high end bite will suffer. It's always a compromise.

    Now, that makes perfect sense to me. But i'll take it one step further, and suggest that the reason for it, is because you're trying to squeeze different frequencies out of the same speaker. Sure, you have 4 speakers in a cab, but they're all trying to do the same thing. How are they supposed to put out big gut wrenching bottom end, when they're vibrating away making high end at the same time?

    Well, what if your amp had 4 speaker outputs, and your cabinet had 4 inputs, one dedicated to each speaker. the 4 speaker outputs on the head could have some kind of built in crossover, so that different frequencies could be assigned to each output. Or, even better, each output would have a dedicated active tone control.

    If you wanted huge bottom, you could have for example, your top left and bottom right speakers churning out some huge, fat lows, a 3rd tuned for midrange, and the last one for highs. You could mix and match speakers however you wanted too. I really think this would give you 100X more control over tone shaping, which is after all what it's all about.

    Anyone have any thoughts on this?

    Mink ya, Zeegs.. My goodness that is almost the same logic that I applied years ago.. utilizing 4 different half stacks..I had a 4 way switcher made for it!!

    I had a Marshall 2210 JCM 800..A Recto (1st series)..a 5150..Ampeg Lee Jackson..then others like a Soldano HR100, Mesa mrk IIT ect..all runnin at the same time..

    I even tried same heads dialed-in differently..and that works too...like two 5150s. One tweaked for chunky lows and one for edgy highs..

    I used to get some big ass sounds that way!

    That was around '91..when Cleveland John and I started fuggin' around with amps together.

    I noticed my Marhsall with my Bogner seem to gel well together on that demo..Uber low mids..Marshall high mids...

    There is sub woofs you could add to your rig. Dime was fuggin' around with that idea with that Randall Warhead with the 15" speaker..John and I gave that a quick try..but we turned it off in a hurry!

    There's guys here that have several amps..I'm certain they know what that's about!

      Well that kinda of goes with my logic of multi-channel amps. As good as they are they sort of half-bake it in order to throw all the bells in whistles in one head case. What ends up happening is they cut corners trying to get t it all in and if you hav a 3- 4 channel head you end up maybe using 1 channel most of the time anyway. A multi AMP set up works better for me, want a blackface cleans? get a blackface, want JCM8002203 balls, get a 2203, want recto tone, get a recto

      Carrying all the shit around can be a problem if you can't get buddies to help ya but for my home studio set up I use the multi half stack, 4 amps through a VooDoo labs amp selector switch..you can run all 4 al the time, or any combination of the 4 amps or just one...whatever you want. I typically like 4 different amps all blended for a noice wall of tone

          What about the other frequency ? Mids we're they called ?

              Cantrell on Dirt used a setup kinda like that for recording. Three different amps, each hitting different frequencies.

                  going back to the topic :

                  2 different amps sound better (MUCH better) - love it , I'll be buying a splitter somewhere soon (radial vs Lehle anyone ? Those wee passive radials maybe ?) and running both my heads in stereo in a fullstack.

                    That's exactly my Marshall 9200/ JMP-1/ JFX-1 and BBE 422 into four Marshall 1960b straight cabs..

                    I used to run two Marshall 2210s before I bought this set up..had this for 11 years now..I like it!

                      unfortunately Bill - only one Fullstack so 1 cab for each head - still pretty brutal - just those damn groundloops :/

                      I understand the way you do it - imho it's cool because most of the people running a stereo rack like the 9200 of yours run it into a single cab - doesn't sound that good and makes less sense imho.

                      My philosophy is to mix two different heads (in fact cabs are also different to some extent ) - one covers certain frequencies which the other doesn't so in stereo the tone is just huge and really full.

                      Btw. Has anybody who runs a stereo setup tried to delay one amp/side by lets say 5/15 ms ? What are your opinions about such a method ? Theoretically it'd give you the sort of "studio" sound ? Right ? Not ?

                        Yeah man I'm following you to the T. I ran my stuff like that, and two cabs is plenty. I never tried the single stereo cab thing...didn't need to I guess.

                        I ran two 5150s..then later two Marshall JCM 800 2210s into a Chandler stereo digital echo with the "high cut" as a tape simulator. I always use the "Catherdal" slap back setting, which is around 366 ms on the G Magor. I always liked the tempo and feel of that setting. Dual channel graphic EQs...and BBE 422 which really woke it up..especially the 5150s. I had a 4 way splitter made so I could play different amps at the same time..that was fun!

                        Don't quote me on that order..I know the delay was last..it's been years since I ran two heads...and I'm baked!

                        The Marshall rack set up was perfect at that time for me..because everything is symmetrical and nicely balanced in one neat package...yeah, you get a pretty big sound like that!!

                        Yes, very "studio" sounding..I was going for classic VH and a "Edge of Thorns" Oliva tone at the time..it sounds much like the recordings!

                        I play a much heavier style these days but it still works very nicely for me...I'm married this rig too!!

                        ...sweet

                            Good idea! It's not an original idea (about assigning amps to certain frequencies).

                              Ah yes, but my original idea is about using a single amp that has separate outputs assigned to different frequencies.
