Let There Be Rock: A '68 Marshall Super Lead In A Box! *** Sound Sample Just Added ***

Sounds great

Thanks.

I made this short clip this evening to give people an idea of how the prototype currently sounds.



Enjoy!

Sounds great to my ear. Did you design the circuit or borrow it?

Thanks Mike. I did design the circuit. But to be 100% open and honest, I did borrow from the amp itself for things like the values of the resistors and capacitors in the tone stack (though I am strongly considering scaling the tone stack down), coupling caps, bypass caps, and the bright cap values in order to authentically capture the frequency response and feel of the actual amp as much as possible.

I'm 99.999% sure there's a percentage of "borrowing" in all amps and pedals made since Adam was a boy so you're in good company! Which amp/speaker did you use to record your clip?

Yes. It is very difficult these days to be 100% original. At the fundamental level, electronics devices such as op amps, transistors, or tubes for that matter only work in one way in terms of getting them to amplify an audio signal. Well, a couple of different ways for op amps; inverting vs. non-inverting for example.

So you're left with the topology of the design to make it uniquely your own. Obviously when you're designing something to simulate some else it hard not to borrow from the original. There might a number of different way to achieve the desired result; whether it be clipping diodes in the feedback loop of an op amp or in this case, cascading three mosfet gain stages. You're still copying the frequency response and gain characteristics despite whatever technology you decide to use.

For the recording, I used overwound PAF-style bridge pickup in a Les Paul-style guitar directly into the pedal and then into my modeling software (Amplitude) using a Fender-style clean and a 4x12 cabinet loaded with Greenbacks.

It was a pretty quick and dirty. I am not very experienced in recording and I don't own any microphones to milk cabinets etc. So my options were limited.
