I chose this pedal because it’s small and cheap, and luckily it also turns out to be very good! I have an electric 12 string which has always sounded muddy and lacking in class, and after trying numerous other possible solutions, decided an EQ might work. First time plugging in, and I was able to make the sound perfect. So, me being me, I dismantled the pedal and removed the switch and sockets and built it into the back of the guitar! Simples! And the power consumption is much less than quoted - 3mA with the LED on, and 2mA with it off - so it’s fine to rig up with a battery.
Nice sturdy box too for those who want to use it the normal way.
