The GoudieFX 808+ is clone of the ever popular (or infamous) Tube Screamer, the sound of this pedal is so popular that I left the frequency response and filters as they are (LPF/HPF right at 723Hz for that characteristic TS mid range honk). However, I did add the less/more mod, the mod doesn't affect the tone or frequency response but provides less gain at minimum settings (4 vs. 10) and twice the gain at maximum drive settings (200 vs. 100). This mod makes the pedal much more versatile allowing you cover cleaner and more overdriven sounds without changing the signature sound of the 808, hence the 808 "plus" you get the classic tube screamer sound with less/more gain if you want to use it.
The signal path for this circuit implements the usual GoudieFX upgrades which consists of increased AC hum rejection caps, improved audio grade resistors and capacitors throughout. The old JRC4558D chip is socketed so you can experiment with different op-amps if you want, every op-amp has a slightly different feel/sound. When you purchase a GoudieFX 808+ I will provide a modern RC4558P op amp, this op-amp is low noise, audio grade with JFET inputs. The original JRC op-amp is from the 80s and has poor electrical properties compared to modern op-amps, personally I don't think it sounds as good as modern audio grade op-amp.

For best results I recommend using with Tube Amplifiers, especially vintage 50s/60s era tube amps or their clones
Not recommended with solid state amplifiers or direct recording inputs, but feel free to experiment, it will work in a bind nonetheless.
