Caline does not, to my knowledge, but there is one from Mosky: https://www.amazon.com/Andoer-Boost...d=1485874665&sr=8-1&keywords=mosky+xp+booster Mosky is one of those super-cheap brands. I should preface this by saying that I actually bought a real Xotic EP Booster. I had bought a few other clones of Xotic pedals that I liked and decided that the EP Booster was interesting and unique enough (and usually hovers around $120, so not the most expensive "nice" pedal in the world) that I should flip some money their way. I cannot speak to the Mosky version, but it looked good in videos. I got the SHO (Super Hard-On) clone because I've heard that is literally one of the simplest circuits in all of guitar effects. The Mosky SHO boost works quite well, though IIRC, it's a little sensitive to electrical interference with some power supplies. The boost pedals are a such a primitive effect - I can swear up and down that this one is special and different from the $40 EHX LPB-1 you're using, but it's probably a very subtle difference. Where you use them in the chain and how you use them will have a bigger difference than the "quality" from pedal to pedal. All that being said, the Xotic EP Booster is so nicely made and has a nice warmth to it (plus a couple of DIP switches for added flexibility), so I'm happy with the purchase. If I wasn't on a pedal embargo, I'd probably be buying others from Xotic.
