RZ-01 CHEMICAL Z
Dual Channel Overdrive

  • Signature overdrive pedal inspired by Maxon OD808, OD808X, and APEX808 circuits.
  • Designed by Tube Screamer creator Susumu Tamura.
  • Features "MagicIC used in APEX808 and Tamura-Mod Tube Screamer mods.
  • Less compression & more even frequency response than a standard 808.
  • Increased output level.
  • Two footswitch-selectable clipping modes
  • NORMAL MODE—for standard 808-style overdrive.
  • HOT MODE—engages alternate diode pair for increased gain, output, and different EQ curve.
  • 9V battery or external power options.
  • Buffered Mechanical Bypass switching.
  • Made in USA.


"A new overdrive based on the mild, natural drive sound of the legendary TS808, with even harmonics added at lower volume levels than the symmetrical clipping diodes would activate, producing rich integer harmonics.

Equipped with a HOT/NORMAL mode foot switch, both modes have excellent high-mid performance, a transparent, comfortable, and well-defined sound.  HOT mode is a higher gain, sparkling, easy-to-listen distortion for playing solos."

-TS Originator Susumu Tamura / June 7, 2024


Roy Z
is a household name in the Metal community.  His extensive resume boasts the privileged position as guitarist, collaborator and producer for the solo sojourns of not one, but two of Metal’s most iconic frontmen – Rob Halford of Judas Priest and Bruce Dickinson of Iron Maiden.

In addition to his work with these vocal titans, Roy has produced over fifty albums for a variety of artists in the hard rock and metal genres.

Most recently, Roy has teamed up once again with Bruce Dickinson on his first solo album in nearly 20 years—The Mandrake Project.

The Chemical Z overdrive was designed to replace Roy’s multi-drive setup with a single pedal that would not just meet all his dirtbox desires, but exceed them.

Designed by Tube Screamer creator Susumu Tamura, the CHEM-Z circuit is based around the “Magic” IC that was only found in limited runs of the best-sounding vintage TS808’s. This IC was also used in the APEX808 that Godlyke released in 2020 under the Maxon Custom Shop banner.

This special OpAmp offers less compression and more output than the typically-used JRC4558. In addition, it produces both even and odd-order harmonics in a similar manner to the preamp & power sections of a tube amp.

More than just a copy of previous designs, Chemical-Z has been optimized for use with high-gain amps. Rich in integer harmonics and with a precisely-tuned upper midrange, CHEM-Z is aggressive yet articulate; edgy yet easy on the ears.

This crunchy clarity not only breathes new life into tube amps, but is also the perfect “plug-in” for adding depth and dimensionality to digital modeling units (Roy uses CHEM- Z to warm up the sound of his Quad Cortex).

Chemical-Z also features a footswitchable hot channel that activates an alternate set of clipping diodes. These now-defunct Panasonic DA2S00100L diodes were used in the Maxon OD808X Overdrive Extreme and have more forward voltage than standard diodes, functioning in a similar manner to the red LED’s that other builders (Keeley, Earthquaker Devices, Fortin, Catalinbread) use in their OD circuits. The result is more gain and output level, but also a noticeable bump to the low-midrange that helps thicken things up for soloing.

This dual-channel design also allows CHEM-Z to be used with clean and semi-clean amps, creating a 3-channel, “clean-crunch-crush” monster rig with just a single pedal.

As with all TWA models, only the highest quality components go into the production of Chemical-Z, including ALPHA potentiometers, Marushin & Neutrik jacks, KOA/Speer resistors and WIMA, Nichicon, Kemet, & Vishay capacitors. CHEM-Z is hand-assembled in the USA using our very own nimble little fingers.

We are once again extremely honored to work with two luminaries in their fields to bring you a pedal that is at the apex of its class. Our heartfelt thanks go out to Roy Z and Tamura-san for partnering with us on this project.

We proudly present to you the Chemical-Z!

Love these
Size: 8.5, Color: Coffee
So comfortable, stylish, and easy to wear. This can be used with any outfit, whether it’s casual or something more dressy like for work. They are comfortable and easy to wear for eight hours at a time. Heel is nice and thick and very stable, which makes for walking in a heel very comfortable. The color is a beautiful nude, which does not look too chalky or too brown. This is a stable in my

Great nude shoe!
Size: 10, Color: Nude
Perfect nude dressy heal. Was not uncomfortable at all. I thought my toes would be sliding out. I did put grips on the bottoms because they are a tiny bit slippery and I am prone to falling. Cute and didn’t distract from my dress.

Only wear for short distances
Size: 8, Color: Nude
These heeled sandals were very cute and flattering. After a couple minutes of walking, my feet began to hurt. I got blisters upon removal. A few days later I tried wearing them again, it is still extremely painful. Great for pictures though!

⭐️⭐️⭐️⭐️⭐️ Comfort, Style, and Performance — Perfect for Daily Runs and All-Day Wear!
Size: 11, Color: Black/Dark Smoke Grey
I purchased the Nike Men’s Quest 6 for my son, and he’s been absolutely thrilled with them. From the moment he put them on, he noticed how lightweight and supportive they felt — a great balance between cushioning and responsiveness. He wears them both for running and casual outings, and they’ve held up beautifully. The breathable mesh upper keeps his feet cool even during longer runs, and the midsole cushioning absorbs impact nicely without feeling too soft or unstable. The grip on the outsole provides solid traction on roads and gym floors, giving confidence with every step. Design-wise, they look sleek and modern — the classic Nike styling pairs well with both athletic and casual outfits. After several weeks of use, the shoes still look almost new, showing how well they’re built. Pros: ✅ Lightweight yet supportive — great for running or walking ✅ Comfortable fit right out of the box ✅ Excellent breathability and cushioning ✅ Durable construction that holds up with daily use ✅ Stylish design that transitions easily from workout to casual wear Cons: • Runs slightly narrow, so consider sizing up if between sizes Overall, the Nike Quest 6 offers exceptional comfort and quality for the price. My son says they’re some of the most comfortable shoes he’s ever worn — perfect for both training and everyday wear. If you’re looking for a reliable running shoe that combines performance, durability, and style, this is an excellent choice.
