This metal box sells for under £30 and has the same old EQ bands as the Behringer and Boss boxes.
The red dots on the sliders do not light up.
Test points underneath:
Sliders are on a daughter-board that makes access to half the circuit tricky.
The same board is used for the guitar version, active frequency bands listed for both.
The op-amp used is the 4560. I'm sure there are lower-noise devices...jack sockets on boards.
Input/output, flip-flop for soft switching, etc., I guess are under the daughter-board
Capacitor mounting looks unexpectedly substandard.
