Dialling in the Marshalls

Check me here, but didn't Dave Meniketti play a Cameron on 'Summertime Girls'? A guilty pleasure song.

Years ago I heard a live version of this song on the radio, and that tone still lives rent free in my head. Some delay, and a 'Marshall...but BETTER' thing going on there. (I have not been able to..as yet...find that rendition.)

Never found the Atomica to be a great amp for me...but I may have to revisit with a brighter cab...it just seems dark to me.
That is a KILLER song and great guitar sound. the Atomica definitely likes bright guitars and cabs.

@Moke and a few others suggested the PPIMV 'mod' for the Brit 800 so it got me excited to do a video about my favourite Axe-III 'mods'.

My favorite video from you to date.

Another little anecdote to consider:
When modding Marshalls for higher gain sometimes the modder will decrease the input frequency response to reduce noise and fizziness. You can do this by reducing the high-cut frequency in the input EQ. Or you can use a high-shelf filter which is a little more subtle. Another technique is to put a capacitor across the second-to-last triode stage. This is the "Triode 1 Plate Freq" parameter. Reduce this to around 2 kHz to start which is typical of amps like an SLO100, etc.

Great video as always.:cool: Try that PPIMV 'mod' on the 'Dumble' based models too...:eek:
Diving into this today, can't wait. i've always struggled with D style amps.

This was definitely one of the most enjoyable ones to make. I'll definitely be trying these tweaks too.

Yo dawg, I heard you like marshalls, so we put in a marshall in your marshall so you can ac/dc when you ac/dc
That needs to be on a tee shirt.

Great video series. Will be revisiting these.

My first Marshall was a Plexi but with 6550s. Lost a fair amount of my hearing to that, but what a glorious sound. Wish the AXE had been available then!

The 50w Plexi 6550 is one of my favorites in the Axe; was yours a 50 or 100?
