Does anyone have, or know of schematics for a early QR? Three bottle version. 2005ish
 
I know they are out there so if you don't get a response here, I'd post in the main forum.
 
Do it. There are plenty of dudes on here that can at least point you.

They probably just never come in here. :dunno:

Exception: If this is one of Scott's originals that you own, please consult with Scott under warranty.



CAN i ask why? What are you trying to do? @Bash_Man seems to have a pretty good handle on all things splawn :yes:

I don't have the schematics. I had an amp tech do all the mods for me, I just came up with the ideas. LOL 😂
 
All good bro @Bash_Man - I was more thinking depending on what TS wants - there may be a solution :yes:
 
I have a 2005 QR. I am just curious to see the tone stack, and how it is connected. I am learning how to mod circuitry. I might want to change the voicing a tad bit. My amp is FAR from any warranty. Because of age. It's a three bottle early one. Thanks all.
 
Cool.

I know there are schematics out there. I am assuming you bought the amp used? Lifetime warranty is not transferable. Here is my opinion for what it is worth.

The early 3 pre Splawns are highly sought after. If you are new to modding circuits, this may not be the amp to 'practice' on. I'd change the tone stack on a cheap amp first. I'd attempt this first on an actual point to point turret board style circuit. I'm guessing your 2005 is a printed green circuit board - which makes modding more difficult.

What are you wanting to change?

Have you messed with pre amp tubes, running a volume pot in the FX loop, running an EQ pedal in the FX loop, running OD pedals out front, etc etc?

@Bash_Man could probably confirm or deny this :yes: as he has actually modded Splawns, as well as a few others here.

:dunno:
 
I would 100% agree with @311splawndude . I would not use that amp as a modding piece. However, IF you decide to do any modding, add toggle switches so you can go back to Factory setting/sound should you choose to. That's what I had done to my Nitro so i can retain that factory sound.

Cheers
 
I'm probably not going to mod anything on this amp. I would love to see how everything is layed out on paper though. I have made a few pedals and switching systems. I am not an electrical engineer for sure, but circuits interest me. I'm trying to bridge the gap between seeing it on paper, and seeing it on a circuit board, and what affects what. I'm hoping to learn how to change voicings by putting in or removing capasitors or resistors (probably with a switch). I am pretty handy with an iron. I love my QR. It does rip! And yes, I do boost it sometimes out front. I have a eq in the loop, and I have rolled many a tube through it. Good fun stuff.
Thanks to forums like this, I have learned a lot. 🙂

Right on man :cheers:

I'm glad to hear this post.

1. Don't try to mess with your QR
2. Do a Google search on Splawn Quick Rod Schematics, you may have to dig a bit but they are there
3. Get yourself an amp building kit. Ceriatone might be a good start. Bruce Egnator did something similar
4. Follow some of the current threads on RT - there are building and modifying amp threads right before our eyes
5. Respect your Filter Capacitors :yes:
6. Have fun

Thanks! I have been reading yours and others posts for some time. I do dig a bunch that is being talked about on these threads. Oh, I have downloaded a couple QR 100 three bottle schematics. But, I am not sure they are comparable to my amp. Like I said before, seeing whats on paper and translating it to an actual board is still not a thing I am good at..... yet. 😁

I can read those at a high level. Learning how the power section interacts with pre amp section is pretty fascinating. So are Transformer. I actually have a few splawn schematics but would rather people find them on their own. Scott was always very protective of his stuff. I got in trouble once for posting gut pics on the Splawnforum. My bias tutorial. Have you seen that. I laugh now when I look back on that. Jeepers.

Also, see Matts post on main page about a supposed Marshall for sale for $1500. That looks like a good modding platform.
