- Amp played through a '70 Marshall 4x12 model 1960 with T1221 Pulsonic Pre Rola Celestion Greenbacks. Guitar: '08 Gibson 1959 Reissue, R9. Hot Plate Power attenuator: -12 dB.
The way you edited this to show us the circuit and the actual board broken into parts was the coolest amp-related thing I’ve ever seen! Thanks!
Ultra-toneful and a very useful transformer and era reference, John! Thank you, you Rock!!
Another great video Johan. This head sounds great!
Thanks, yeah it's a beast :-)
Love this series Johan. Thanks for putting in the effort. Old Marshalls rule. Could you do a video about your guitar?
Thanks, I was actually planning to, I'll fast track it now. Cheers Johan
Johan Segeborn Cool! Thanks!
My Goodness Johan,That amp is harmonically rich as they come! Great playing again too!
+Craig Morrison Thanks, yeah I loved that amp
You are doing a great job with these video's. Thank you so much for doing this. I am a huge Duane aleman fan and it is cool to see what he might have used. Without your video's it's hard to see how loud those guys actually were. I think he used a 50 watt super bass. They must have been super loud in use without an attenuator.
***** Thanks man, yeah in a normal sized room a super bass is just to much. Even a 50 watter at full volume (just a couple of dB quieter than the Super Lead/Bass) is to loud. 20-30 watts is feasible though.
Cheers
Johan
Johan Segeborn I bet! I always wondered how loud it was at the fillmore east! I have a mesa F-50 and the video you did on the rectifier and JVM to make them sound plexi was very interesting. Makes me think about moving to marshall but I love the f-50. I am a blues/country /rock and (gov't mule ) type of player.
***** Hi, the sound on stage was probably quite unpleasant. My super lead is about 100 db at 2 feet, when set at volume 2-3 and attenuated down to 5 with the Weber Mass, so at full volume unattenuated, we're talking jet plane :-)
Johan Segeborn Wow. That is Loud! I would never be able to play that loud in any venues I play in. Can't imagine what it was like back then. Sure does sound good recorded!
Yeah in smaller venues, they sure needed a dedicated audience. But people took music more seroiusly back then, so many were probably ok with it.
Sounds great ! Thanks Johan ! :)
Mitchell Ferre Thanks Mitchell! :-)
We have the rare dual output version from 1965, awesome head!!
Cool as always! What the hell were these used for back in the day? Were they for two guitar players or what?
Thanks, I think it were intended for vocals and speech mainly. Interesting question, what did they actually use these for?
Hendrix used it as a backup amp.
Sounding better.
Thanks Nick, glad to hear that. Cheers
Hi Johan,
Great playing today. I like your new (to me) riffs. So... This one is very interesting to me. I agree with your comment "as thick as it gets". My Vintage Modern gets a similar fat tone that's pretty close to this. I guess it's the KT66's. I like it, but sometimes, with the gain up in HDR, it gets a little muddy. I have an eq into the front and it helps, but I think in the end, I'll have to get another head. I love the 1959 but I guess it's a bit too much for any stage I've ever played on, mostly small bars. So either I have to get into a popular band or get a smaller head. Maybe 2061? But, those just don't have the oomph that I really crave. 1987's are pretty potent as well, maybe 2204 is the way to go, I had one once, and wished I still did, but.... Anyway, thanks again. You rocked this one!
Thanks man, yeah the VM has the same type of sound but not as open and punchy. I'm gonna demo a Germino Masonette 25 next week. It sounds very much like a superlead but at lower volumes, check that out. A model 1986 bass is good too and I think they sound plexi-ish all the way into the late 70s. I know the 1992 does. Cheers
Hi Johan, I am looking for an original Plexi Super Bass. Do you know of any available?
Hej, den lät inte alls illa!! Skulle vara kul att se detta i en clinic.. Kanske på en mässa nära Göteborg. Tror du skulle dra ganska mycket folk. Jag skulle i alla fall åka mina 40 mil. (Sounded great, would like to see him demo this in a clinic, near Gothenburg)
Tack, den är verkligen ett monster. Ska du på Fuzz mässan i Göteborg nästa vecka? Hälsningar Johan
Johan Segeborn Japp, jag o basisten åker för att gotta oss i alla gosaker!
Gott, då ses vi där!
We have 1965 version of this in stock with dual transformers :-)
That amp sounds incredibly loud!
I can tell you're a fan of Marshall... Have you thought of doing the same thing for Fender amps?
Yes, I have. But I'm gonna go through Vox first :-)
fender will be next, Cheers
which power cord did you use for jtm45?
Its like a Marshall vintage modern? With Kt66?
Hi! Yeah it has the KT66s! Can get similar sounds out of a VM. Cheers
Any Paul Kossoff fans?
These things are gods - but you can only make them gods when driven. And the gods side with the police. so...best avoid :)
