"Needed to mod this, and it is clunky to use."
A clunky piece of kit that is tricky to operate, does no frequency sweeping, and shows crossover distortion.
I gave it 3 stars because had to modify it. I added breadboard sockets to the generator outputs (the bnc connectors are not much use), labelled pots and outputs to show what they do, and am adding a +-12V solid state volt factory so that the device only requires 5 V supply to operate. That said, this device is giving pleasure with generating stable frequency waveforms of various sorts.
