Here's your chance to own a pedal that is based on one of the most massive PCB's available. The AionFX L4 Preamp. For this price, you couldn't even build one yourself, and you'll be thankful you didn't. It has two distinct switchable channels, one of which has an incredible parametric mids control. The compressor circuit is designed to limit the output of the entire circuit (or your entire signal chain if it's the last pedal before a power amp) and it does add a nice squish to the signal, but not like a Dyna Comp type thing. This thing is priced to move. It has all premium parts, and I have definitely calculated they cost more than the price I am asking for this pedal. Full disclosure though, the Bass knob on the "red channel" has a wonky shaft. You may never have noticed it but in case you did, now you know sooner.
