okko pedals OKKO FX Master MasterWouldn't it be great if you could just turn up your amp for certain parts in your set? The MASTERMASTER system offers two switchable volume settings for every amp with an effects loop. It consists of two units: The small VCA UNIT (voltage controlled attenuator) is plugged into the effects loop of your amp and controls the volume in a way a simple potentiometer would do. It is optocoupler based, the signal doesn't pass any active or mechanical
Wouldn't it be great if you could just turn up your amp for certain parts in your set?The MASTERMASTER system offers two switchable volume settings for every amp with an effects loop. It consists of two units:
The small VCA UNIT (voltage controlled attenuator) is plugged into the effects loop of your amp and controls the volume in a way a simple potentiometer would do.
It is optocoupler-based, the signal doesn't pass any active or mechanical elements.
The REMOTE CONTROL UNIT can be placed anywhere (preferrably on your pedalboard) and controls the VCA unit via a regular guitar cable.
Set both controls to the desired level and switch between the settings.
This system offers many advantages over using a booster either before of after the preamp:
– no alteration of the amp sound
– no added noise, no risk of ground hum, no phase issues
– no switch clicks or pops
– fail safe (if unpowered, the amp runs on the set volume)

My go-to energy drink for years, no crashes or headaches
Flavor Name: Zero Ultra, Size: 16 Fl oz (Pack of 15)
Consistent energy, good taste, and no weird side effects
✔️ Sugar-free with no crash
✔️ No headaches or jittery feeling
✔️ Clean, smooth energy boost
✔️ Good flavor without being overly sweet
✔️ Reliable enough for long-term daily use
✔️ Subscription makes it easy to keep stocked
I’ve been buying Monster Zero Ultra for years and have it on subscription. It’s the one energy drink I consistently go back to. I've tried most others and they all leave me feeling weird.
I actually feel a noticeable energy boost from it, but without the downsides I’ve had with other drinks. No headaches, no weird jittery feeling, and no crash later on.
The flavor is also solid (this one and Ultra Violet are my go tos') , not overly sweet, and easy to drink regularly. I only buy sugar-free energy drinks, and this checks that box without sacrificing taste. I limit myself to one a day after the gym and water the rest of the day.
After trying a lot of different brands, this is the one that’s stayed consistent for me, which is why I’ve kept it on subscription.

Clean, Crisp Energy Drink
Flavor Name: Zero Ultra, Size: 16 Fl oz (Pack of 15)
This energy drink has a light, crisp flavor that is noticeably less heavy than many traditional energy drinks. It has a slightly citrus style taste with a smooth carbonation that makes it easy to drink without feeling overly sweet or syrupy.
The zero sugar formula keeps it feeling cleaner on the palate, which I appreciate when I want something refreshing instead of something thick or overly intense. It goes down easily and does not leave a strong aftertaste.
I find the energy boost to be steady and consistent, without feeling like an abrupt spike. It feels more balanced, which makes it easier to use during long work periods or when I need to stay alert without feeling overwhelmed.
The 16 ounce can size is convenient, and the pack format is practical for keeping stocked at home or grabbing on the go. It is easy to chill and stays refreshing cold.
Overall, this is a smooth, lightly flavored energy drink with zero sugar, consistent performance, and an easy drinking profile that makes it a reliable option for everyday energy needs.
