Today I wanted to talk about the Fulltone GT-500 FET Distortion + Booster and Overdrive Guitar Effects Pedal. This pedal uses the FET, and since I’ve been personally interested in building pedals, I wanted to see what FET was. Basically FET is a type of transistor, it stands for Field Effect Transistor. There are two type of transistors, FET and bipolar. FETs come in two different types (MOSFET and JFET). MOSFET should sound familiar to some of you. Okay, so I have a definition, but I’m still confused on why one is preferred over the other? My basic understanding between FET and bipolar shows that they basically do the same thing, but why is FET preferred in pedals?? If you can enlighten me, please feel free to comment.
Okay, enough nerd talk, we have the Fulltone GT-500 FET Distortion, Booster and Overdrive, so let’s look at it more closely. I’m a big fan of Fulltone products, and this pedal seems pretty special. In a sense it’s two pedals in one enclosure allowing you to control what pedal is in front of the other with the selection switch. This is a pretty cool concept.
Here is the official pedal description:
The GT-500 Effects Pedal from Fulltone is a discrete FET Hi-Gain Distortion and Overdrive Booster in one box. You could think of them as 2 separate pedals, or think of them as stages to be linked together for endless combinations. The Hi-Gain side has Volume, Distortion knobs, Bass, Mid, and Highs minipots. Its Booster Side has Volume, Overdrive knobs, Bass and Highs minipots.
Hard-clipped distortion—the way most guitar pedals achieve distortion—at one point in a circuit can be cool, but stage after stage of FET (GT-500) is very real, very amplike, and has ridiculous amounts of sustain even at low volume. It does the great chunky low-string rhythm stuff and cleans up incredibly well when you turn down the guitar’s volume. The Fulltone GT500 contains 9 FETs, 2 Mosfets, and 1 Transistor with no opamps or clipping diodes used.
What’s special about the EQ? The Hi-Gain side has a discrete Inductor-Driven Midrange circuit—never been done in a pedal before. There’s a wah-wah inductor inside the pedal that gives the Midrange control its ability to drastically increase or decrease the entire Low Mid, Mid, and Hi-Mid frequencies, to comical proportions. All this is done without any opamps—this has 100% discrete matched FETs.
This Mid control mixed with a strong Bass and Treble control help give the Fulltone GT-500 the ability to dial in more variations than a simple tone control, which can only roll off the Highs.
The Series Select Switch allows you to choose which pedal comes first (allowing you to instantly change the order of the 2 circuits). For example: A clean boost slamming into the front end a Distortion sounds way different than a Distortion followed by the clean boost, and when the EQs of the respective sides come into play, it’s a wide-open canvas. Regardless of which side of the effects pedal is designated as first in line, you can still use each side by itself, completely independent of the other side.
I found a great video by Tone Factor going into some great detail of what this pedal can do.
You can pick up the Fulltone GT-500 FET Distortion + Booster and Overdrive pedal for $199.00 at Musician’s Friend.

Today, I found another great deal on a Carl Martin pedal. This time it’s for the Carl Martin Boost Kick pedal. This pedal lists for $231 and is on sale for a scorching low price of $70.09. I’m not sure if this pedal is out of production, I do not see at Musician’s Friend. Either way, $70 for a booster of this caliber is not bad at all. The pedal also ships with FREE super saver shipping. At the time of this posting, there were 4 available. Normally, when the stock gets down to 1 (sometimes 2), the price will jump up, so if this sounds interesting, you best jump on it.
