Arcane Analog Master Blaster Germanium Treble Boost. A fantastic sounding hand built Dallas Rangemaster-style pedal.
These are much more flexible than typical Rangemaster and the majority of boutique clones offered as the tone/range control allows you to dial in the amount of treble/bass that works with your guitar, amp and sound. In other words, you can get wide range of boost/tone options that can be tailored to your playing.
Hand built in Canada one at a time with the best quality components you can find.
