Greer Vintage 390

The Greer Amps Custom Shop 390 Vintage OD/Preamp came about after a request from one of our first endorsers. Seeking a vintage sounding overdrive that can get harmonic crunch, Mr. Casey Meyer asked us to build him a pedal that was modeled after the vintage DOD Overdrive Preamp 250. 

This is our answer. The 390 is an awesome sounding drive, featuring only two controls--Gain and Volume. 

This pedal can go from light grit to nasty snarl with the turn of the Gain control. Featuring a vintage-correct LM741 chip, this pedal sounds awesome. 

Now...did we just go and copy the old pedal? Hah. Nope. We changed some things around. We upgraded all components, including all signal capacitors (Panasonic ECQ series and Nichicon KW audio series capacitors), resistors (metal film where needed for noise reduction), and even added diode protection and some light power filtering to help out when the 390 is running on a power supply. 

This pedal is currently limited to the first run of 30 total pieces. Don't wait...order NOW!



This pedal features a high contrast, laser etched, black and white faceplate, with white knobs, so you can see your settings on a dark stage.

The 390 also features true bypass, like all Greer Amps pedals, and runs off a standard 9 volt, 2.1mm, negative center power supply. 

We recommend using a high quality, regulated, and filtered power supply with all of our pedals.
