Great sounds, good value and ultra compact
Nijoho, 21.06.2018
This is booster/overdrive pedal. Apparently a Klon clone, but as I've never had a Klon, let's just consider it on its own merits.

Firstly, it's not True Bypass, but there are some claims that the bypass buffer improves tone even when the device is off. Let's just say this must be very subtle, because I really don't hear any difference. Maybe you will, pretty sure your audience won't. But I like this as an "always-on" pedal, that juices things up a bit all the time, and in that role, it really excels.

If you back off the gain control, the volume control is going to work like a booster. It's not really a clean boost, and there is definitively some nice (but restrained) lower mid increase, leading to that "your guitar, only better" feeling. The volume control has plenty on tap to push my amps in to great tones.

We also have the Gain control, which will bring in some overdrive from the pedal, and its a wonderful thing to behold (or hear). Rich, warm and open. Plenty of overdrive here for my needs - very often I'm just using it to add a bit of breakup - but it might not be enough for other peoples tastes. Its does seem to stack well with other pedals, though.

The small enclosure is handy, its super simple to use, and very easy to find plenty of great tones. Oh, and the gold livery looks great on my pedalboard too (yes, I am that shallow).


- No True Bypass. Mine's almost always on anyway, so not something I worry about, but if it's a deal breaker, take a look at the Deluxe version of this pedal.
- The blue LED is maybe too bright.
- No battery power possible.
- Its small to the point of the controls being fiddly to use.

A Very Flexible Pedal
Johnny Boy, 23.05.2019
I use this pedal as a fairly clean boost for my American and British style pedals. It works well with both of them. The knobs are a little on the small side and respond to small amounts of adjustment so it's a little fiddley to fine tune but great sounds can be had.
