Let me first say I have not tried a Klon so I'm not able to say which of these two pedals is closest to a Klon. Also at this moment I don't have video capability so I'm just gonna verbally compare the two pedals. I first went out and got the MO, with 1n34/0a126. I found this pedal to be awesome on all settings. Sweet, articulate, full, and blooming. I a/b'd it with the archer on every setting imaginable, going counterclockwise to clockwise on tone, gain and vol controls. The MO had a touch higher volume so I adjusted accordingly. On each setting I played, I did it twice with pedals reversed in order since they both have buffers and I did not have a true bypass ab box. In any case my conclusion is is that both pedals are nearly identical. I mainly tested MO in 1n34 setting to compare but in higher gain territory I also used the oa126 setting. I really could not tell much of a difference between the two pedals. There were moments when I felt the MO was a bit warmer and sweeter but then there were other moments where I felt the archer was a bit warmer and sweeter. I played both chords and lead lines. I'm only gonna keep one but it's a hard decision. I like the smaller size of the archer but I like the additional option on the MO of the different diodes. I really like the oa126 setting at the higher gain setting. I know I'll probably use the pedal with the gain set at 9 to 10 o'clock but I do like knowing I have the oa126 diode if I decide to go higher gain. Anyway these are first world choices. They are both truly excellent pedals at excellent prices. If I get a chance at doing a video I will do so. Hope this was helpful
