Up for sale is a Fulltone GT-500 in excellent condition. This is a massive, incredibly versatile, all-analog gain station that packs a discrete FET High-Gain Distortion and an independent Overdrive/Booster into a single tank-like enclosure.

If you are looking for a highly tweakable gain solution that can cover everything from a completely transparent clean boost to a saturated, amp-like roar, this pedal handles it all with ease.

Key Features & Highlights

Two Independent Pedals in One: The Left side functions as a JFET Booster/OD (great for clean pushes or mild grit), and the Right side serves as an multi-stage FET High-Gain Distortion. Both can be run entirely independently or stacked together.

The "Series Select" Order Switch: A killer feature that changes the signal path on the fly. You can run Booster > Distortion to slam the front end of the high-gain side for massive sustain and compression, or flip it to Distortion > Booster to act as a pure, uncolored volume solo boost after your main gain stage.

Inductor-Driven Midrange EQ: The distortion side features a discrete inductor-based Mid control (rare for a stompbox) that allows you to surgically scoop or sweep through low-mid, mid, and high-mid frequencies without sounding harsh or sterile.

True Amp-Like Response: Built with 100% discrete matched FETs and zero op-amps, meaning it cleans up dynamically with your guitar’s volume knob and behaves exactly like a hot-rodded tube preamp.

Built Like a Tank: True to classic big-box Fulltone build quality, featuring a heavy steel chassis and custom rugged brass-shaft pots mounted directly to the interior PCB to ensure long-term durability.

Condition & Operational Notes

Cosmetic Condition: Excellent. Minor handling marks or faint signs of light pedalboard use, but exceptionally clean overall (see photos for exact condition details).

Operational Condition: 100% fully functional. Every single knob, mini-pot, and toggle switch operates smoothly with zero scratchiness or signal dropout.

Power Needs: Runs smoothly on standard 9V DC center-negative power, but handles up to 18V if you want extra dynamic headroom and clarity.
