There is more then Eds pickup(mighty mite-Dimarzio super distortion)that achieved the van halen 1 sound,the dimarzio SD or the mighty mite would not be enough alone to achieve the distortion that Ed achieved on van halen 1,look at all the guitarist back then that used the dimarzio super distortion and the mighty mite pickup,none of them sounded like Ed,did Ed use those pickup,yes,but there is more to that,remember jose explaining to me,overdrive-distortion unit was used to achieve THAT sound I dont know way people dont take that into consideration,but people believe guys that worked on Eds gear in the 90s,
Spaceace,im not the only one that believes that(overdrive-distortion unit) many amp builders-techs do, people who know marshall plexis,and know them well,such as Doug Roccaforte,Ozzie at Blockhead(which he now works for 3-Monkey)and others I dont need to list all of them,they know that no stock cranked plexi can achieve that type of distortion, even using a variac or a high output pickups or a master volume wouldnt matter,pickups do help to a extent, People need to go back and listen to Van halen 1 and then compare it to some of the clips that are here and on other sites and hear what is missing.
There was a Big Muff in the 70s.
If anyone has used a Big Muff then they will know that that thing is a full on overdrive pedal that imparts it's own sort of thing onto any amp.
This is Ronnie Montrose using a Gibson LP Jnr through a Big Muff and a Bandmaster recorded with Ted Templeman and Donn Landee

If anyone has used a Big Muff and then listens especially for the Big Muff then I think they will probably recognize the Big Muff in the tone especially on the lower notes.
The Bandmaster has no real mid boosts in the circuit and the Big Muff overdrives the amp by upping the signal strength from the pickup and puts it's own clipping distortion sound in the mix as well.
Ed doesn't really need a pedal with something like a DiMarzio Super Distortion or Mighty Mite Distortion and his Marshall amps were mainly circuits which boosted the mids.
In fact, when Ed starts using the PAF is probably when a pedal might be used but he still doesn't use a pedal, what he does is he jacks up the PAF height for maximum output and just plays with a bit of a cleaner tone.
There is also the MXR EQ which Ed could use to boost the signal hitting the amp if he wanted to.
As for Box 1 and Box 2, the DOTG photos show Ed playing the Franky going straight into the phase on the pedalboard and then out from the pedalboard with the EQ and Box 1 disconnected (no Univox in the chain) and Box 2 is totally unconnected and not used at all, so Ed is not using Box 1 or Box 2 in these photos at all but there are other DOTG photos where Ed does use Box 1 for Eruption with the Univox.
The EQ connects directly to Box 1.
For Eruption, Ed is using the Franky (actually Franky is offstage just after playing Eruption) and it's going straight into the EQ and then into Box 1 and then out from the pedalboard and this makes sense when someone realizes that the Univox has a pretty low input impedance and will end up sucking all upper mids and upper content out of the tone so it really needs a buffer of some sort in front of it, something like a EQ.
My opinion of Box 1 and Box 2 is that Box 1 is a dual Univox footswitch and signal through/cut switch and Box 2 might be used to bypass the Box 1 switch with just a straight signal in/out that gets sent from Box 1 to Box 2 as Box 1 seems to have a short lead that can connect to Box 2 and Box 2 could be optionally used for daisy chaining with another amp so Box 1 and Box 2 could be sending the same signal to different amp chains if Ed felt like it but Box 2 is not used in the DOTG photos.
