Tubeworks Real Tube 903 Modded Tone Stacks

So as most of you guys know when I'm studying for exams I tend to do a bunch of layouts when taking breaks to keep my sanity. So since I did a layout for the Tubeworks 903 I thought to myself if it's basically a tube pre-amp I thought why couldn't the tone stack be modded to that of some legendary amps. With that in mind, I modified the original layout I made with various tone stacks.

Original schematic can be found on Revolutiondeux.

Layout 1: Fender


Layout 2: Marshall


Layout 3: Vox


Layout 4: Hiawatt DR103


Layout 5: Sunn 1st Gen Model T


Layout 6: Orange OR120 MKII


Layout 7: Matamp GT120


Layout 8: 72 Ampeg SVT


Layout 9: Marshall Superbass


Layout 10: Dumble Overdrive Special 70's



Layout 11: Dumble Overdrive Special '97

Tubeworks Real Tube 903

JohnK had made a layout for the 903 awhile ago, and since I did a layout for the 901 i thought I'd see if I could make a smaller layout for the 903 to make it easier to put this in a 1590BB with plenty of room. I took his switch wiring to make it true bypass, and removed the additional LED to tell you that it's got power, which I feel is unnecessary. Schematic can be found on Revolutiondeux.





Tubeworks Real Tube 901

JohnK had made a layout for the 903 awhile ago, so I thought I'd give the 901 a shot. The layout should be small enough to give you plenty of room in a 1590BB. I took his switch wiring to make it true bypass, and removed the additional LED to tell you that it's got power, which I feel is unnecessary. Schematic can be found on Revolutiondeux.

The 901 has higher gain then the 903.

Electro-Harmonix Signal Pad

With 1000 verified layouts in site, I figured I'd throw in something small, simple, and usable.

From the Source:

The Signal Pad is a passive attenuator that allows you to instantly switch to a different preset volume. It's like your guitar's volume knob, with a fully-passive and color-free circuit. Leave your amp's volume set high for overdrive, and use the Signal Pad to lower your level for a clean sound -- then switch it off to kick in your amp's natural overdrive. You can also experiment with the Signal Pad anywhere in your effects chain -- you'll bring out new tonal combinations from your favorite old pedals.

Basically a simple switchable volume pedal.

Mictester - Silicon Tonebender

Found this while searching for some schematics for Silicon Tonebenders I came across it on revolutiondeux. Miro posted a layout awhile ago for the Hot Silicon, which is pretty much the same, the difference being the trimmer off the gain control (abuse) which lets you set the gain rather then having a set resistor. Since my layout different then his, and the added trimmer I figured it was worth adding.


Here's mictester's advice on tweaking:

"Adjustment: set the 1k "Abuse" pot halfway. Play though it, and adjust 5k preset until "gating" just stops. That's it!

You'll find that it has plenty of output, that the "Abuse" control gives a good range of colour, the "Sparkle" control has a very wide range and the sound is remarkably reminiscent of early Jeff Beck (certainly not a bad thing!).

Possible mods:

Put small value capacitors from base to collector of the middle two transistors - start with 47pF. This "smooths out" the sound a lot, but reduces the treble available.

If you have radio interference, put 100pF from base of the first transistor to ground.

Experiment with the capacitor values in the tone control - the 8n2 could go as low as 3n3, which would give a ridiculous range of treble control!

Increase the value of the 47k feedback / bias resistor - try as high as 470k. The gain will rise, the touch sensitivity will disappear, and it will become a high gain screaming monster! "

Silicon Tonebender MKII

I saw a request for a Silicon Tonebender MKII based on a perfboard layout over on StompBoXed's page, which is the modified Tonebender MK II Professional. So after making a layout for it I started searching for other Silicon Tonebenders.The other 2 schematics can be found over at DIYSB.

Rockett 10 Ton Hammer

"The Rockett Pedals 10 Ton Hammer is a perfect distortion pedal for players who have a clean amp, like a Fender. It may not play nicely with high gain amplifiers, thats just the nature of the high gain game. This is a highly responsive pedal, and with some creative use of your guitars volume and tone knobs, you can even achieve some bluesier tones for added versatility. But really, subtlety isnt this pedals primary job. It is here to crush, kill, and destroy, but in a very musical and harmonically rich way. Get back in tune with the old school overdrives that made you wanna rip some killer riffs and leads in the first place. The Rockett Pedals 10 Ton Hammer will unleash a pummeling tone with all the intensity of a monstrous wall of distortion"
Original FSB thread and schematic available here.
Layout Updated! Connected 10K resistor from Bass 1 to Ground instead of Vb.
