AUDIO PATH UPGRADE - ALL MODELS - 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 - ALL MODELS - 49.00

MAJOR UPGRADES FOR THE ARP ODYSSEY:

LFO FREE RUN SWITCH - 2800 thru 2813 - 55.00 all others 45.00

It's impossible to get a slow moving sweep on the LFO while playing the Odysseys 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 - ALL MODELS - 2800 thru 2813 - 59.00, all others - 49.00
