Took time to make a song demo of my homebuilt Marshall. Hope you enjoy:

Sounds killer! I hear a little Angus influence, maybe? What tweaks did you make to the circuit? I haven't heard a 45/100 sound so... crunchy (in a great way!).

• Higher power filtering
• .68uf cap over V2a

Thats really it. I also used solid core wiring instead of stranded, but I can't imagine that doing anything for the crunch.

I usually don't play it that "crunchy" actually. I run it at around 6 (instead of 9) and use a vintage ts9 to get my drive into the lead area. But I wanted a guitar-cord-amp setup for the vid to show what all this stuff can do. Glad you dig it.

Its funny, I LOVE angus young, but I've never followed him or anything. My learning background is really All stevie ray vaughan. But playing in a cover rock band and using a JTM45/100 my sound gravitates towards his sound. Its natural since he's really just a blues player playing the crap out of a marshall straight in. Though... I would say I consider HIS tone to be the quintesential Marshall tone.

Right on. I watched your TS vids and I can now see the SRV thing. But in the 45/100 vid, your vibrato is very reminiscent of Angus. I'm about to start a 50w build, and I'm planning on putting switches on lots of the various lead/bass options, including the V2a .68uf cap, tone stacks etc... It would be cool to be able to switch in and out filter caps, but I don't know if that's possible... I'm curious to see what combination I end up liking best.

Anyway, sounds good. Keep it up!

Thats funny. I actually built a "prototype" amp build using an old Traynor amp. I did just what you said. I built a 50 watt marshall and then built in switches for lots of stuff. Bright cap, split cathode, cathode bypass cap on v2, even a rotary switch with diffferent NFB resistor values.

I then gigged with that amp for about a year until I settled on switch positions I liked best. I then built this 45/100.

[papillon]

Ha! I almost bought a Traynor a few weeks ago to use as the basis for my build. But in the end, I calculated that the cost of the parts for a fresh build wasn't much different, and that the Traynor iron would impart it's own thing to the mix. I'm also not really concerned about having my build be totally accurate to the original. I have a metal panel small box from '69 or '70 for that itch. I'm planning on putting the new chassis into a shortened head cab, and maybe do something creative with the knobs/faceplate. Today's photoshop mock-up:

Awesome video. Not enough 45/100 videos on the internet. I'm actually about to start buying some stuff to do a 45/100 build. I'm doing Marstran iron, I'm going to use the PT that does 560v, hopefully it wont kill Gold Lions too quickly.

Awsome clip...great playing and sound

There is a ceartin Angus vibe over it for sure.

Thanks...Standard Seymour Duncan '59s.

want to make a note that after recording that, I've since found that:

•my bias drifted cold (newer tubes...)
• one of my screen resistors was bad
• PIckups a bit high on the guitar.

I need to make another clip.

[Ydna]

Would you mind making some clips of some strat stuff?

I've made two MP3s soon after the build was complete.

This one is with an ultimate attenuator, still pretty loud:

This one is with the Faustine Phantom attenuator at lower the bedroom volumes for an attenuator test:

Soundin' good, man... Real good !

You asking about the original pickups? Still got them in my sock drawer. Kinda dull sounding pickups. Those 70s Humbuckers are not all that great. But it does make me wonder if trying them again might be a cool idea.

[JimiJames]

Nah.... don't put 'em back in... Sell them to me...

I am searching to replace my stolen early '70's Wine Red LPC with another with '69 appointments.
I'm either going by way of vintage or newer or entertain a new Hot Mod '55 LPC w/ wrap-around but, will still have Waffleback tuners and Witchhat knobs...
It's inevitable I do get another LPC and without a doubt, will have T-Tops.

Anyway, soundin' great, man. I do like the voice of yer amp.
