Crazy Tube Circuit Space Charged Oveedrive V2. An incredible handmade overdrive. With the adjustable volume and gain for the 2nd stage that can dial in tube driven glassy clear drive sounds as a clean boost or hi gain boost for the first channel, or have 2 stages of clean or drive boosts all in one box. Dip switch for fatter bottom end thickening great for beefing up single coils, and a tight mid range focused setting that gives humbucker happy tones. FYI Reverb has the comp prices showing vs the Space Charged V1, so if this shows as being above comp, please check comps this is lowest price online Reverb keeps comparing this to the V1 and stating its overpriced. You can remove the backplate and swap in a 12ax7 for a heavier OD or a 12at7 for cleaner sounds making this a crazy versatile.
