Ground Zero modded 75 Marshall 50w 1986 Bass spec 4 stage plate fed design

[@eldoradoguitars6456]

Really digging this one Jeremy. Raw and pissed off but still organic and not buzzy/fizzy. Killer job!

That’s a good way to describe this one. It’s cleans up amazingly well with guitar volume too. Goes from clean to blues to mean without touching the amp.

As with all your work this is super tight and the clarity is awesome! 🤘🤘🤘

Nice, man! Sounds awesome. I'm always going back and forth around Plate fed and Cathode follower.

[@brejnae]

What is main difference in sound?

[@groundzeroampworks780]

They’re both great. The plate stack takes some finesse to get it tight and the highs under control. I probably prefer CF overall but the wild sound of a plate stack is fun.

[@ironageamplification1791]

@@groundzeroampworks780 I've noticed that as well. I love the mid-range throatiness that I've found in one of them I tried. It was a 5 gain stage and I placed a 33k cold clipper as the 3rd stage, and the rest were very similar in the cathode structure to the Snorkler Mod. I think I kept most of the coupling values higher than I would on a cathode follower circuit.

[@groundzeroampworks780]

@@ironageamplification1791 no cold clipper in this one. In fact, I rarely use them ever. Elevated preamp voltages at the PI supply really help in this type circuit.

Sounds sick. Out of curiosity, have you ever worked on Laneys? Such as the GH and VH series?
