I went a bit down a klone rabbithole, watching lots of youtube videos etc. I don't recommend doing that with this style of pedal as I have learned you really don't know til you plug your guitar into your amp here. I tried another klone that jumped out to me from the shootouts as head and shoulders better than all the others, and liked it for a particular sound enough that I thought - "ok, try another highly regarded one before deciding". So I ordered the Centavo.
Its big! Really big. You can fit 2 boss style pedals and a mini pedal probably if you wanted to in the same space. But, sonically it blew the other pedal entirely out of the water. Not in the same category at all. The volume on the guitar rolls back perfectly. The amp reacts as though the amp controls are on the pedal. The gain range is my style of nuance in the low to medium gain, and when you want a lot of gain it puts that somewhere at the end of the sweep. Very practical. It stacks beautifully with my other gain pedals.
I never tried a real Klon. I have, however, bought and returned my fair share of overdrive pedals (thank you Thomann). I don't like what most pedals do to the sound of my guitar, the way the strings react to my picking hand especially. There are exceptions - Barbershop and Hot Cake, for example. But generally I think I would be happiest straight into an amp except Im the singer too and thats my main focus when Im playing live. So, pedals mean I don't have to stress too much, just sing and stomp when I need.
This pedal reminds me of some outboard studio gear (which Warm Audio also clone) - just running your signal through it improves it. Its almost a bit too hi fi for my slightly messy, exposed, low gain and aggressive style, but the reactivity and musicality have me kind of addicted.
Highly recommended if that classic sound shape and behaviour is important to you, and you hear the difference between the Klon sound and an overdrive with a lot of mids. If the Klon thing is an occasional colour on your palette, then I think you will feel a bit overwhelmed by the real estate this thing commands.
