API TranZformer LLX Transformer / Bass EQ, Boost and Overdrive Pedal

The API Tranzformer LLX is the latest in APIs line of guitar pedals. 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.
