FILTER UPGRADE - 59.00

Avatar filters have a upper frequency limit of 11khz! This frequency response upgrade is similar to the 2600 filter upgrade extending the cutoff frequency range from 11khz to 28khz. Also replaces some critical components in the signal path. Your filter sub module is removed, tested, upgraded, re-tested and re-installed into main board "C".

AUDIO PATH UPGRADE - 49.00

This mod replaces critical signal path components with audiophile grade components. Low end response is improved resulting in a more accurate wave shape. This mod used to be called the "Low end wave correction mod" in the early days of CMS. High end response is also Improved.

POWER SUPPLY REBUILD - 49.00

Certain critical components in your power supply have a shelf / working life of 20 years maximum. It's probably time your power supply was rebuilt. These units are getting very old, so if you are serious about your ARP, you should get the Power Supply Rebuild.

LFO FREE RUN SWITCH - 45.00

It's impossible to get a slow moving sweep on the LFO while controlling the Avatar from a remote keyboard. When this switch is in the free run position, the keyboard will not restart the LFO as with stock units. Contrary to misinformation on the web, CMS is the originator of this mod.

ADSR TURBO SWITCH - 49.00

This mod installs a switch in your Avatars ADSR section that engages the turbo mode speeding up the time constant on the ADSR to attain 2600 type percussive envelopes.

PORTAMENTO ENABLE - 59.00

Stock Avatars have their portamento circuits hardwired to the guitar section. This mod rewires the portamento so that it slews the keyboard cv input.
