The "narrow box series with round switch" was a rather popular series between the "first series" and the latter (and fugacious) "narrow box series with square switch". New models were introduced, namely the CP-835 Compressor II and the three knob Phase Tone PT-909. With the launch of the CP-835 the former CP-830 was discontinued. The second issue of the ST-800 Stereo Box (with LED and flying fingers) is extremely rare.
