I have a 2nd gen QR that I absolutely love. I decided I wanted to learn more about my amps and decided to build a kit from metroamps. I built a 1959 SLP 100 watt head with the PTP board. The thing sound killer and have started to mod it a bit and will continue to tweak it. Does anybody out there know how Scott gets all his gain. The layout for the QR and SLP is quite similar and they ony use 3 pre amp tubes. Obviously his modded SLP's have the gain I am talking about. Does he use any diode clipping to achieve the gain at low volume. Whats the secret if there is one?

Scott could probably tell you his secret..of course he'd have to kill you since it's his livelihood and it's copyrighted and all that good stuff....
and by the by, no diod clipping...that much we do know..the rest remains a mystery
glad you like the amp though!

I'm not looking for the exact recipe. Just a basic idea behind it. Thre are so many gain mods to a SLP and 2203. MV vs. PPMIV, one wire mod, cascaded gain stages and so on.

The idea is that each preamp tube has 2 gain stages... How he does it I have no idea...

I think the basic idea is he changes values of various resistors and capacitors, and re-structures the gain path. As to HOW or WHAT he does, that's why he is a successful amp designer, and I'm NOT!

If you talk with most old-school amp designers they will likely tell you there's only two main circuits in existence: Fender and Marshall. Everything else is based on those. Mesa tweaked a version of their own as have many other builders since then. But fundamenally, most of the circuits are more similar than you'd imagine (or so I've heard mentioned repeatedly in talking with techs over the last 20+ years). Realize, there's lots of ways to alter tone outside the circuit itself. The type of transformers, chokes, filtering and type of components. There's a numbe of different varieties of capacitors and resistors. Then factor in the various tube types an amp can be designed for. And class A vs. class A/B. All of these things impact the end result before the circuit design itself even comes into play.
So in short, there's many variables involved, which is a good thing really... or else we wouldn't have as many different amps too choose from. But a bad thing if you are somebody who tends to perpetually have GAS. hahaha

One other thing...
I've found that 90% of the people who are exposed to amp building find out pretty quick how difficult and "unglamorous" it can be trying to build amps when compared to playing "rock star". And subsequently loose interest. Just one more reason to be thankful of Scott and his great amps, and to continue to support Splawn as much as possible.

If I remember correctly, Marshall started out copying Fender almost exact and tweaked from there, just like Mesa did. So I guess you could trace it all back to Fender as far as modern guitar amps go. |

You may have to climb to the mountain
pray and ask God himself for the secret...
ask Scott and see for yourself!

Yep. The old Marshall Bluesbreaker was based on a Fender Bassman, except it used KT66s. |

Not exactly sure but it has something to do with a Flux Capacitor and 1.21 gigawatts of electricity. Oh yea and plutonium.

I think the clue is in his mission statement's "personal relationship with Jesus Christ." Some people sell their souls to Satan to become rock stars, some make a deal with Jesus to make the best sounding amp in the world!  |
