API TranZformer GTR

A Classic API EQ for Your Pedalboard

The TranZformer GTR is an API EQ — and it fits on your pedalboard! The TranZformer GTR is centered around a variable-gain preamp, which can be configured as an undistorted clean boost or as an overdrive that pushes this stompbox's 2510 input amplifier into saturation. You also get a guitar-optimized 3-band EQ for classic API-style sonic sculpting. A muscular-sounding transformer output puts the final sonic stamp on this guitar effects pedal's signature API sound. What's more, the TranZformer GTR has been engineered for high-performance operation with a standard 9-volt power supply. This studio-quality stomp boasts high-quality buffered bypass switching to ensure an optimal signal, even if your rig includes arena-sized cable runs. An easy-to-see indicator LED rounds out the API TranZformer GTR's outstanding features.

Variable-gain preamp with classic API sound

When you plug into the TranZformer GTR, the first thing your signal hits is the pedal's variable-gain preamp. Teeming with classic API character, this preamp includes a Gain knob with 0dB to +40dB of gain; more gain delivers more boost or overdrive. The Mode knob toggles between an undistorted Clean Boost and an Overdrive mode that drives a 2510 op-amp into saturation. The guitarists here at Sweetwater really appreciate the TranZformer GTR's Output Pad, which inserts a -20dB pad into the stompbox's output — a must-have if you're planning to plug straight into a guitar amplifier's input.

Guitar-optimized 3-band EQ

After your signal leaves the API TranZformer GTR's preamp, it passes through a 3-band EQ with guitar-optimized frequency curves and ±15dB of boost/cut. The high-frequency band is centered at 5kHz, the mid-frequency band at 1.5kHz, and the low-frequency band at 200Hz. All three bands feature peak-style filters; the high-frequency band also includes a switchable shelving filter type.
