All purchases from this page will also get you a link to a special AMZ web page for customers only, which includes a wealth of information about using the parts you have purchased. For example, the page for germanium transistors includes schematics to several original designs never before published, such as the "Germanium Power Boost", "GE1 Fuzz", "GE2 Fuzz", "Brownie" and more! Different pages are sent for mosfet booster pcb, mini-booster pcb, germanium transistors and so on.

Voltage Doubler PCB
The AMZ V-Dub pc board is a charge pump voltage boost used to increase the 9v pedal power to 18v (approx). It can also output a negative 9v power supply for PNP transistor pedals. The board measures 1.0" x 1.9" (25.4mm x 48.3mm) and is sized to fit into the Hammond 1590A aluminum box. A link to a web page with detailed instructions for assembly and use is emailed to everyone who purchases the V-Dub pcb.

A single pc board is $10.00 US which includes shipping to anywhere in the world. I prefer Paypal payments.

Multi-Purpose Opamp PCB
The new AMZ Multi-Purpose Opamp pc board can be used to build one of several projects, including a guitar direct box, opamp booster, boost-and-buffer and others. Each board purchase includes a link to a page of example circuits (with parts lists) that may be used with this board. Read more about this versatile pc board and the projects that are available for it. Board size: 1.25" x 1.9"

A single pc board is $10.00 US plus $2.00 shipping to anywhere in the world. I prefer Paypal payments.

Multi-Purpose Board for Transistor Boosters & Buffers
This is the Multi-Purpose pc board that can be used to build a variety of circuits to use as boosters or buffers, including circuit designs with bipolar silicon, germanium, jfet and mosfet transistors. Each board purchase includes a link to a page of example circuits (with parts lists) that may be used with this board. Read more about this versatile circuit board. Board size: 1.3" x 1.5"

A single pc board is $10.00 US plus $2.00 shipping to anywhere in the world. I prefer Paypal payments.

Germanium Transistor Buffer
This is the board for the germanium transistor buffer board that is mentioned in the Guitar FX Blog. Each board purchase includes a free germanium transistor that can be used to build the buffer. Printed instructions with parts placement, parts list and mods are included with every board. Read more about this easy to build circuit. Board size: 1.3" x 1.5"

The original buffer boards are gone but this circuit can be built on the Multi-Purpose PCB. Use this Paypal button to order and I will send you a germanium transistor with your Multi pcb. A single pc board is $11.00 US plus $2.00 shipping to anywhere in the world.

Mini-Booster
This is the board for the classic mini-booster circuit that has been used in numerous boutique booster pedals. There is more information about it on the AMZ Mini-Booster page. The instructions sent with the board include directions for making several different versions of this fat sounding signal booster.

Printed instructions with parts placement, parts list and mods are included with every board. Board size: 1.25" x 1.9"

A single board is $11.00 US plus $1.00 shipping to anywhere in the world. I prefer Paypal payments.

Mosfet Booster
Another classic AMZ booster circuit, the Mosfet project is available online for your reference. This circuit makes a clean signal booster with a flat response and very little distortion. Many people claim it adds a 'sparkle' to your guitar sound!

Printed instructions with parts placement, parts list and mods are included with every board. Board size: 1.25" x 1.9"

A single board is $11.00 US plus $1.00 shipping to anywhere in the world. I prefer Paypal payments.

Mail Orders - If you do not have a Paypal account, you can send an order by mail. Use our Parts Order Form which includes complete instructions and the address.

Why buy boards from AMZ? - These boards are for projects and designs that I created. Shouldn't you support the original source so that more projects will be available in the future? AMZ projects are thoroughly tested and confirmed to operate properly. Also, I offer complete support for your construction project in the form of a special help page (url is on the printed sheet that comes with your board) and by email.

Are you interested in further information about the mini-booster and its derivatives? Then look at the AMZ Projects Newsletter and the information available on the AMZ CD-ROM!

Transistors have been tested and guaranteed less than 300uA leakage.

The AC128s are sold out. I suggest the 2N1309 transistors below as an excellent replacement!

Order AC128 transistors SOLD OUT!

The AC188 is a PNP germanium transistor that is the penultimate in transistor distortion devices. Boutique pedal maker Jacques claims that this transistor "works miracles with electric guitars".

A set of 2 of these AC188 transistors is available for $12.00 US. Shipping is and additional $3.00 to anywhere in the world! Transistors have been tested and guaranteed less than 500uA leakage.

The AC188s are sold out. I suggest the 2N1309 transistors below as an excellent replacement!

Order AC188 transistors SOLD OUT!

These are 2N404A germanium transistors (PNP), which are low gain (hfe>30) and excellent for a variety of vintage circuits. I suggest using one of them for Q1 in the Fuzzface type pedals. I checked a few for leakage and they were less than 100uA. These are NOS and have gold-plated leads. I got them from a supplier of military surplus parts.

Order 2N404A transistors SOLD OUT!

These are 2N1309 germanium transistors (PNP), which are high gain (hfe>150) and excellent for a variety of vintage circuits. I suggest using one of them for Q2 in the Fuzzface or for HOT Rangemaster pedals. It is a good replacement for the AC188 which Boutique pedal maker Jacques claims "works miracles with electric guitars". I checked a few for leakage and they were less than 100uA, with many less than 25uA. These are NOS and I got them from a supplier of military surplus parts. UPDATE: These are almost gone...
