The ultimate always on overdrive!

Klazo Drive is a dynamic rock-n-roll machine with an eminently useful tone stack that will blast your socks off!

Klazo employs carefully selected MOSFET arrays that deliver musical signal clipping across the entire frequency spectrum.

Incredible Pedal
Written by Trey Bentley on Sep 29th 2019

Got the Klazo a month ago, and immediately connected with it. Do you like warm butter on your biscuits??? Well, if your pedal board is a biscuit, the Klazo is the warm butter. Definitely a fan for life.

Best OD EVER!!!!!!
Written by Ron Bentley on Sep 29th 2019

Got my Klazo OD and Wow!! I always go straight to the amp with any new pedal, a test drive(no pun intended),so to speak. This pedal will not disappoint. The settings are sweet when not used as a boost,and beast when you do. For that Keith Richards break up,to pile driving OD. It's the one. It is on my pedal board,made it the first day,and it is in the company of some mighty fine pedals,they have alot to live up to,the Klazo is the king. Thanks for such a great product,the shipping was rock solid and really quick,and the questions were answered almost in real time. Amazing company,amazing pedals!! Can't wait to have the whole line of Greenchild!

Klazo Drive

I recieved the Klazo Drive yesterday and spent most of the day playing it with my Fender American Strat with Fender Lace Pickups in front of a Vox Ac-39 2x12 Blue Alnico speakers and this pedal comes as advertised. It’s a tone machine with exceptional clarity. I rolled back the gain and push the volume up and my Strat just comes alive..very touch sensitive. I pushed the gain up past the 3 o’clock position and it pushing Vox into that near breakup that you would expect from an overdrive pedal. It’s just so much range and with the tone controls you get a wide range of tones..especially when you drive this pedal. It’s a definitely always on pedal for me and it works very well with other drive pedals as far as stacking. I’m currently using it with the Greenchild Mr boost and the Reaper and it’s simply amazing..highly recommend and it’ll be a permanent part of my effects chain. Thankyou Mason and Greenchild Amps.

Klazo Drive
Written by Scott Rodolitz on Sep 24th 2018

My Klazo Drive arrived today and it's fantastic! There really is no other pedal that I know of that's even like it - the 'EQ' of the Bass and Treble allows you to totally sculpt the gain in a way that's remarkable and unique. I had bought it for my Baritone playing (and it was everything I hoped - the bass strings, even in A to A didn't muddy up, and in B to B, the higher strings really sang!) But it sounded so good, that I soon pulled out my regular guitar, and found that these same qualities shine through, and that I was able to get GREAT rich tones on it, that will make it even more useful for my regular guitar playing! In fact, I liked it so much that I took the afternoon off and played all day! Keep on making great pedals, Mason! Thank You!
