Arp Explorer I

This Explorer I is fully functional and in great condition.  It has been modified in-house with inputs for CV & Trig.

The Explorer 1 is great sounding early model Arp synthesizer with the Moog filter design.  It features 4 selectable octave footages and 5 preset waveforms including pink noise,  24dB/oct low pass filter, ADSR, LFO, Repeat, and Vibrato.  Some what slept on, the Explorer I offers the classic Arp arp sound in a compact body with just enough flexibility to make the standard preset synth palette your own.
