This is hands down, my favorite pedal. Guitar, bass, bass vi… hell, I’ve even run a sm57 through it. The klone v2 is based on the hotly debated but indisputably famous Klon centaur circuit. Known for its beautiful clean boost and subtle drive control. There are many cleanboost/light drive pedals out there which are similar, like the Archer or the Morning Glory. Besides the exceptional build quality, the klone v2 has never left my board for a few reasons. The pedal has three parameters, level, tone and gain, going left to right. If you want to use it as a boost to clean up a long signal chain, or push the front end of an amp, you can keep the drive all the way down. The boost adds not only a few db but seems to add upper harmonics and tighten lows without affecting the color. Perfect for if you want to stand out during solos without driving the sound engineer crazy. The tone knob is something else. I don’t know the physics of what it’s doing but it doesn’t seem to be the same parametric eq spike most tone controls have. I have found it cleans up unwanted harmonics and fluff in a signal dependent on the type of instrument, strings, pickups, effects are before it. So it’s not as intuitive as some controls but I normally approach it like “turn the knob until it sounds good”, let the pedal do it’s thing. Lastly there is the gain control. Again, I don’t know what kind of gain circuit it uses outside of the same as the klon, but for me, it’s the best sounding standard gain for a guitar or bass for 90% of what I do. I use it as my “clean” tone. Which still has enough harmonic saturation to give it some grit, but none of the dirt. Now for recording, I love, love, love an excuse to crank the gain and let this thing really sing. I can’t overstate how much I love the tone from this thing. The only thing even close is how well it takes other pedals. For my bass vi rig I have the klone v2 near the end, after a ce-2, POV, carbon copy & ds-1. It manages to tame alllll of that, coming from a bass vi which no one builds for, and gives me a clean, tight signal before the flint, or di. If anyone wants to come by the studio and try it out, just let me know. I haven’t been able to shut up about this pedal for years and hopefully neither will you.
