Monte Allums Guotar Pedal Mods



DISCLAIMER - Absolutely no refunds. All sales are final. We cannot be held responsible if you ruin your pedal. I got ripped off by a buyer of my TR-2 mod. Said he wasn't happy with the mod so I offered to buy the TR-2 from him. I gave him $110 in good faith. When I received the pedal it was non-functioning. He had drilled the hole for the pot in the wrong place piercing the ribbon going to the depth pot and completely pulled 4 traces from the PCB. And he wanted to know why the mod sounded bad. Because of this I will no longer issue refunds of any type on mods. If you do not have the skills required to perform the mod then please let us do the mod for you. Monte Allums

TS-9, TS-808 & OD-9 Tri-Gain Mod

NOTE: The Maxon OD-9, TS9, TS808 & TS-808 Pro have the exact same PC Board

Our TS9 Kit will also work with a TS808 and a Maxon OD-9. Well, I have been listening to your requests and have given them to you in this mod. You wanted more gain, you got it, you wanted more clarity, you got it, a brighter LED, you got it, you wanted us to incorporate our popular Tri-Gain Option and you now have it.

With these mods I feel this is now the best Tube Screamer Mod available by anyone at any price. The combinations available with the two switches make this an extremely versatile overdrive.

We've doubled the gain and added a Tri-Gain Switch that lets you choose between two LEDs, two 1N914 Diodes and a Diode Lift in the middle position. The LEDs will give you a coarser gain that is thick and fat with added bass and volume. The 1N914 side will give you the stock gain of a Tube Screamer and the middle Diode Lift position gives you an incredible volume boost with tons of crunch. The other switch toggles between two Metal Film Capacitors of different values. One of the Capacitors firms up the mids and bass while the other Capacitor adds presence and clarity. Very useful when switching between both single-coil and humbucker equipped guitars. One of our most popular mods just got better!

Tube Screamer Tri-Gain Sound Sample - This mp3 was recorded on a Strat with a DiMarzio PAF Pro at the bridge and two DiMarzio Virtual Vintage pups at the neck and middle positions. The amp was a 2000 Fender Hot Rod Deluxe and the mic was a SM57.

TS9DX Tri-Gain Mod

Well, I have been listening to your requests and have given them to you in this mod. You wanted more gain, you got it, you wanted more clarity, you got it, a brighter LED, you got it. You wanted me to incorporate Tri-Gain and Presence Switches like I offer in my TS9 TG Mod, well you got them! With these mods I feel this is now the best TS9DX Mod available by anyone at any price. The combinations available with the mode knob make this an extremely versatile overdrive.

The two TS9 modes are perfect for electric guitar with gobs of vibe and smooth overdrive. The Hot and Turbo modes can also be used with electric guitar but in my opinion just rock when used with a bass guitar and will give you mucho bass with thick creamy mids and a velvety thick overdrive. So one pedal, two uses.

TS-9, TS-808, OD-9, TS7 & TS5 Tube Screamer DIY Pedal Mod Kits


I will be adapting the above mod to the TS7 and TS5 and maybe a couple of the Maxon Overdrives as well. Please do not e-mail me about the availability of them. When I am happy with the adaptation of the Tri-Gain mod with these pedals I will release them. I have no idea how long this will take so please be patient. Just creating the instructions alone is a very time-consuming task. So, please do not e-mail me about the availability of these mods. Also, please do not ask me to upgrade you to the above mod if you have purchased one of our previous Tube Screamer mods. I will not be offering an upgrade for them. The reason is I don't feel the Tri-Gain switch alone would be a good upgrade for them. There are other components that need to be changed to take advantage of the switches. Monte Allums

NOTE: The TS9 and TS808 have the exact same PC Board. Our TS9 Kit will also work with a TS808. These Mod Kits are the result of months of research. I took several Mods that others are performing on the net and performed them on a Tube Screamer. The ones I liked I kept. But I went further, I painstakingly tweaked each Mod to perfection.

I tried different Resistors, Capacitors, Diodes (Carbon Composite, Metal Film, Tantalum, Germanium, etc.) and I used the best analyzers in the World (My Ears) to determine which sounded the best. I discovered that there's an awful lot of hype and Mojo floating around about the Tube Screamer. This DIY Kit Goes Way Beyond a TS-808. Although, it does include the famous Texas Instruments RC4558P chip and the famous "Brown Mod". But this Kit doesn't stop there.

Hear For Yourself! (.mp3)

TubeScreamer Song.mp3 — These mp3s were played on a Custom-Built Strat with a Special Tuning System I invented called the "eNut". Notice how incredibly in tune all the mp3s are. With this system you can accomplish amazing intonation on any guitar. Other system are 2X to 10X its cost and don't work as well.
