Vintage ARP Little Brother Synthesizer Expander Desktop Module Axxe Odyssey 2600

Description

No ARP owner should be without a Little Brother.  The Little Brother synthesizer expander module can be used to add an extra oscillator and LFO to one of your vintage ARPs.  The Little Brother has a genuine ARP 4027 oscillator submodule in it–this is the same oscillator as used in the legendary ARP 2600.  Four selectable and stackable waveforms are available — brass (sawtooth), hollow (square), reed (pulse), and fuzz (pulse with PW modulation).  Four selectable and stackable registers are available (16′, 8′, 4′ and 2′).  An on-board LFO provides Vibrato, with an optional Vibrato Delay.  Pitch is bendable over a 2 octave range.  Tini-D Jacks provide input/output multiple pairs for Trigger, Gate and CV as well as an output for the LFO.  RCA jacks provide an input/output multiple pair for the audio.  There’s a great demo video on Youtube showing the Little Brother in action, check it out!

This Little Brother has just been refurbished by Synthchaser, including the following work:

• New sliders installed
• Power supply recapped (high quality, high temperature 105 deg C capacitors used for the filter capacitors)
• All tantalum capacitors replaced (except on 4027 Oscillator submodule which was not touched)
• All CMOS and op amp ICs replaced
• New pitch bend knob
• Calibrated
• Tested with a vintage ARP Axxe

While it works great and looks reasonable, my perfectionist nature requires the disclosure of the following cosmetic flaws.  The ARP Little Brother tag is missing from the front of the unit.  There is a small hole drilled above the Reed switch (the other small hole is from the factory, and used to access a calibration trimmer).  The Reed and Fuzz switches were replaced with NOS switches for proper operation, however only black switches were available.  The Vibrato Delay switch cap is missing.  The lamp on the power switch does not illuminate.  There is a scratch on the panel by the vibrato delay.

Due to current conditions, I am not currently offering local pickup or delivery for this item, shipping only. This is a vintage electronic item, so all sales will be as-is and final.  But visit the Synthchaser YouTube channel and rest assured that a high quality detailed restoration was done to this synthesizer by the expert on ARP Synthesizers.
