Hello, i am currently closed for the Holidays and will open shop back up January 5th.


The TPC1 Preamp Buffer


The TPC1 preamp's are available in 2 sizes, the TPC1 and the TPC1sm(Smaller size). The TPC1sm's output capacitor is switched to a tubular type and the circuit board is altered to accomplish the smaller footprint. The TPC1sm version is specifically made to accomodate those with a smaller/tighter control cavity. Both the TPC1 and TPC1sm retain the same circuit, component material, and identical tone. The physical footprint is the only difference between the two.

A Unity Gain Version is also available in both sizes. Unity Gain simply means the Gain that goes into the preamp is equal to the Gain sent back out of the preamp. The Stock TPC1 is NOT Unity Gain, but for those that need or want the Unity Gain version it can be selected as an option.

When ordering please select the options that best fit your needs.

TPC1 & TPC1sm

TPC1 Notes:

~ A Stereo (Tip/Ring /Sleeve-TRS) Output Jack IS needed for on/off switching purposes.~

~ The Stock TPC1 - is NOT a Unity Gain Preamp. A Unity Gain version IS available if needed.~

~ A Layout for installation is located here.~

~ Strat Type Wiring Layout located here ~


Approximate Preamp Size in Inches:

TPC1 = 1-43/64" X 1-25/64" X 1/2" Tall

TPC1sm = 1-19/64" X 1-25/64" X 1/2" Tall

(NOTE: To help decipher the preamp that suits your needs, measuring out a small piece of cardboard/paper and placing it in your control cavity can help determine which preamp you can use.)



Just a few players using The TPC1;


Jeff Mattson - Zen Trickster's, Dark Star Orchestra

"I currently have your TPC1 Preamp Buffer in both of my main guitars. My newest guitar has the smaller version (TPC1sm) and it was a real easy fit. I love how sweet and clear and natural the sound is. It does a great job of driving my effects loop and keeping a perfectly even tone at any volume. Thanks for accurately re-creating Jerry's Tiger guitar buffer for the rest of us to enjoy." Jeff Mattson, Dark Star Orchestra
