Das API Select TranZformer GTR kombiniert die legendäre EQ-Schaltung von API in einem kompakten Pedalformat für Gitarristen. Es verfügt über einen variablen Vorverstärker, der zwischen einem sauberen Boost und einem Overdrive-Modus umschalten kann, um den proprietären API 2510 OpAmp in die Sättigung zu treiben. Der 3-Band-EQ basiert auf dem klassischen API 553 Programm-Equalizer und bietet eine gezielte Frequenzbearbeitung. Ein zentrales Merkmal ist der signifikante API-Ausgangstransformator, der dem Signal die charakteristische analoge Wärme und Kompression verleiht. Das Pedal ist als hochwertiger „Channel Strip“ für das Pedalboard konzipiert und bietet zudem einen schaltbaren -20 dB Ausgangs-Pad. Es ist Teil der API Select-Serie, die Studio-Technologie für Live-Musiker zugänglich macht.

The LLX incorporates APIs legendary EQ circuit into a versatile and compact bass guitar pedal. The LLX offers +/- 15dB of gain on 3 bass guitar specific frequencies; 100Hz, 400Hz and 2kHz. The gain stage can be switched from clean boost to overdrive, which drives the input OpAmp and adds even more tone. The LLX also features a buffered bypass, -20dB output pad, selectable peak/shelf for upper frequency range, transformer output and of course the classic API sound.

Das Pedal bietet zudem Regler für Wet/Dry-Blending für parallele Kompression sowie einstellbare Attack- und Release-Zeiten. Die Schaltung ist rein analog und darauf ausgelegt, Studio-Dynamikbearbeitung direkt auf das Pedalboard zu bringen. Es ist Teil der API Select-Reihe, die professionelle Studio-Hardware für Live-Anwendungen optimiert.
