The characteristics of the (particular) single 12 breaking up in an open back cab must be considered. This all assumes that the DR will be played at gig volumes, so you aren't starting with a baseline clean sound. This mid-emphasis needs to more than offset the mid-notch in the DR.

I honestly think that what is needed is two dominant mid-emphasized frequencies that have sort of specific clipping for each one, with some other lesser peaks, and some mild notches in between, too.

I think this is also where the MIAB pedals aren't usually a good fit with a DR, because you get a dump truck full of what you only need a teaspoon full of! So a little bit of that will go a long way. And the "buzz/fuzz factor" is kind of important, because the amp will tend to over-accentuate those characteristics by itself. If not, there's no way things are going to be tightened up sufficiently. You need a drive box that simply doesn't have much in the way of bass. So - IMO, a lot of tone controls are not only unnecessary, but they simply won't work. a very finite range before the amp starts to break up on its own, even if pedals aren't used a mushy low end with no 'tight cut' due to the low power, the open back cab, the single 12", and what is a bit of an undersized output transformer a sort of 'jaggy' transition from clean to breakup because of the power section and large negative feedback So, despite what amp sound you might want, with a DR you start with: It's not impossible, but it will require some compromise, and IMO requires a bit of overcompensation or going to what might seem like extremes - IOW, you want a box or combo of boxes that basically will sound like a dogpile thru possibly any other amp.įor most of these types of drive effects to work, you have to start with the amp and work your way back from there. Really any other characteristics that might seem unique to a Marshall in themselves - it's kind of a pointless exercise (IMO). So - just getting the EQ right is insufficient. You HAVE TO start with the reality that the drive box has to accommodate/compensate around the amp. But I think this hits back to just because a drive box has a ton of tone controls, or just because it apes the foundational EQ of a Marshall, that still doesn't mean it's going to work with a DR. IMO, lots of the MIAB stuff might sound kind of neat or convincing if just twiddling around the house for fun, but IME a lot of that stuff doesn't realistically work out on stage.Ī little buzz or fizz actually isn't a bad thing - a bit of what we tend to equate with "Marshall sounds" partly has to do with a bit of aggressive Celestion breakup, at least again IME. I definitely agree on issue #2 that you raise. Since the bass and treble are removed in the same aggressive way as is done with a TS, there's going to be the same 'non-cleanup' with the volume knob as with the TS, no doubt about it. And before the output, there's a chance to add a little sparkle at 2KHz with the tone control. But after both the treble above ~700Hz and the bass below 700Hz get hacked away, the mid control is basically an EQ slider also at 700Hz, but it's only "diffused" over 1/10 of an octave. Kind of apples-to-oranges in some ways, but not completely so. The JD9 has a gain factor of 3.7 while the OCD has one of 1.4. The second stage is basically like what you have with something like the OCD. So the JD9 tears away both the bass and treble just like a TS. Almost forgot - even though the inverted input is used for the clipping/drive stage, it also has the same high pass filter frequency as a TS - all bass below 720Hz is rolled off.

tone control lets you 'recover' some treble, with frequencies below ~2KHz, rolled off is ~700Hz, and the Q is high at ~15 - that equates to not even 1/10th of an octave - STRONG mid bump mid control is indeed an active boost - the bandpass freq. second gain stage is mild gain boost/signal recovery, and is full-range (doesn't roll off any bass at freqs down to ~70Hz) fixed filter that rolls off treble at 740Hz after the first gain stage (identical to a TS) input signal at inverted input of 4558 op amp (TS uses non-inverted input) for a slightly different vibe at what is the only real clipping stage - basically same as a TS9 - soft clipping diodes, small cap to remove upper treble freqs The Jet Driver is (IMO) a TS-derivative with the following:
