This listing is for a Macbeth X-Series analog voltage-controlled dual envelope generator (EG) in mint condition. 

As you probably already know, Ken Macbeth no longer makes these modules (or no other modules, for that matter). This is a very rare item, hard to come by, and is already becoming a vintage, sought-after instrument. Its value will certainly increase as time passes.

Built solid, to last. No cheap plastic parts here. No cutting corners. Quality is in every single little detail, from the pots to the panel to the jacks.  

This particular one is in excellent cosmetic condition and works as well as a new one. It has been very well taken cared for. Please see pictures for details.

Price is firm. I’d appreciate it if you refrained from sending me offers.

Thanks, but I’m absolutely not interest in trades of any type. I’d appreciate it if you refrained from sending me offers.

It will be properly packed and shipped immediately. I assure tight communication throughout the transaction.

Please check my feedback as a seller on eBay as well for additional reference; member name, “thedevilstone.”

Note: You can finance the purchase of this item item with Affirm, which is now one of the payment options. With Affirm, you have the option to purchase it with 0% financing (if you qualify). I would turn on that option upon request. I would have to apply a 3.1% increase to the price to compensate for additional fee Reverb imposes.

From Macbeth:

crucial to the filtering and final output of any synthesizer are the envelope generators. there are various types of egs in different designs and some are simple- some more complex. the x-series dual eg employs a classic adsr design. using totally discrete parts- the switch on timing for this module can be very fast. the x-series dual eg was designed to have three different ranges of operation- fast (which is well snappy), medium which is standard for most analogue synthesizers and slow which is great for long drawn out rise and fall times- perfect for slow evolving ambient music.

as the name suggests, this is a dual envelope generator. typically one would use the first eg to control the cutoff frequency of a voltage controlled filter and the second eg to control the output, or volume of a voltage controlled amplifier. it was thought important to add a built in 'utility' vca for that final output. the vca, like most of the circuitry in this module, is a discrete transistor based design that adds that extra clarity to the final output.

Size is 21 hp.
