Sounds great. I think most people just are too afraid to crank the volume because they are unholy loud, but that is where they truly come alive. Too many people try to keep the volumes down and jam a pedal in front, it's not quite the same. Nice looking Greco too!
Dude! I’ve been on a real kick lately of re-discovering my Aussie rock childhood (late 70’s/80’s). I keep telling folks I know here in the States (been here since ‘89) that we had the best live music scene in the world back then. Time to add some classics to the amp testing repertoire! Angels, Divinyls, Chisel, Oils.
Good to see you survived those monster burgers off the grill! That beast had to be LOUD in the room. Killer after tones and that guitar collection on display is epic as well.
Hey you crazy aussie. Greetings from Texas. Did you visit Texas when you came over? A buddy of mine bought one of these brand new in the early 70s from Brook Mays Music in Dallas Texas. He had to wait a long time to get it here but wow it was worth it. You got this one sounding great. Thanks for the video.
You gone and inspired mate. I’ve got a ‘75 lead and bass head that I haven’t even taken a bias reading on since I got it a year or so ago. Just got my bench finally cleaned off. Time to open her up and see what the hell is going on in there. Has MM iron all around but sounds pretty good even though Heyboer is more my Marshall jam.
Another great vid bro! Man these old Marshall's sound killer and your playing is mean as always. If you're ever home visiting in the tron, I'd love for you to have a look over my '78 Superlead MKII.
I have a Super Lead from the same year. Based off some of your observations, and some of the tones you were getting. I'm starting to suspect that my amp might be modded outside of the capacity that I'm aware of.
@@HeadfirstAmpsWell it turns out my amp was more molded than I thought. Now that it's been serviced, and brought back to stock. It's easily one of my top amps. Amazing tone, with great dynamics and great feel.
A few players here in NZ tell me they do not like Marshall amps. I wonder if they have just tried ones that have been messed up. This Jason bloke constantly gets ones in that do not sound like they should. When sorted out the amps have the sound. The quintessential sound of Rock. The other thing these folks say is Marshall amps are horribly thin and bright. That tells me they never played the amp loud enough to overcome the bright cap. They are surprised to learn early Metallica is not Mesa, it's Marshall. Not exactly thin and bright.
Wow! Jason that amps sounds really good! Just needed some love done to her cool man! I wantesd to ask you what EL34 tube that you like too use in your amps that you really like the most? Thanks
EL34B, Tung-Sol Reissue! I been using these for a while now! But man Tung- Sol here in the states are almost $200.00 I guess having a valve amp is part of it. One thing for sure is JJ are a way on price for sure and my pre amp i been using JJECC83S I'm not what you using and like. One thing for sure going to a store and buying tubes is not that easy! More than me you are in the amp building so i understand were you are at on that.
I assume the reminder of the preamp circuit, minus those Super Bass mods, were classic Super Lead specs for that era of amp? Split cathode on V1 with a 2.7k/0.68uf and a 820R/330uf? 0.022uf and 0.0022uf coupling caps? Did the second gain stage on V2 have a bypass cap?
@@HeadfirstAmps I imagine there is not much difference tonally between a 470pf and a 500pf cap in the treble peaker or the tone stack once you take into account the tolerance factor on the capacitors.
great! I have one like that..from the same year..all stock.. but when i turn the volume up to 7 it sounds very bloated/muddy... any advice? the filter caps seem to be fine according to my technician
Hey Peter, when I’m there by the Mac and the Axe fx I’m using a Suhr Reactive Load (the original one). This is a York Audio Blackback IR 57 and 121 blend. Sometimes I mic that old Marshall cab with a 57 with good results.
Killer tones. I am curious though, is there much tone difference if you internally jump the inputs and have a master volume in place one of the unused inputs?
@@HeadfirstAmps if you have them internally jumped, but have the volume down to zero on volume one and volume up to 5 on volume two, does any of the signal bleed through? Or is just like only plugging into volume two?
