Caline "High Chief" may now be the Brothers Blues King of Tone.

The Caline "High Chief" is considered a King of Tone Clone, but YouTube videos show that they don't sound the same, and the internal diode selector switches don't work on the "Clear" channel. But, the latest model has "Clear" replaced by "Drive".

Now, the Marshall Blues Breaker II pedal has a "Boost/Blues" mode switch, which bypasses the diode clipper stage for a clean boost. My guess is the the old High Chief has one channel on "Boost" mode where the diodes are bypassed, and the new model has both channels in "Blues" mode. 

So, you could add a DPDT switch to either model so you have a "Boost/Blues" on one side, like the Marshall Blues Breaker II for extra versatility. Since both diodes switches off would be close to the "Clear" setting, the new version should be more flexible. The Caline pedal is 43 USD shipped with a one month wait from China, so it cost about the same as a Blues Crab, which is a single Blues Breaker. I ordered one today, so my guess is that all the diode switches will work.

 

Clear becomes Drive

Boost/Blues = Clear/Drive

The gain controlling resistors are over 5 times greater in the online traced KOT schematic, but some of the color codes are painted over on the KOT:

Red painted over yellow

My guess would be that the 33k/27k resistors are really 3.3k/2.7k, slightly more gain to compensate for the 10k in series with the 100k drive resistor. It will be interesting to see if the High Chief has 3.3k/2.7k.

My theory would be that the bottom orange strips below are painted over red on the KOT. There seems to be a 2-tone on the bottom orange on both:

¿Orange over Red?
 

 Note to self, the KOT feedback loop cap on yellow stage 1 is measured on one unit as 750pF, which would cut more treble.
