 	Before I get started with replies - Does anyone on or off the list 
do Eurorack-format custom work? I see that Metalbox does frac-format but 
not sure about Euro. I will almost certainly want to get a front-panel 
module with RCA jacks and switches for my reverb(s).

 	(For reference, here's info on the A-199 Doepfer - 
http://www.analoguehaven.com/doepfer/a199/ - the sound sample on this 
page sounds pretty decent!)

 	It would be great to have a 10 or 20HP custom module built up with 
a switch panel to go between an internal tank and an external tank (with 
the tank I/O on the front panel, to make it easy to swap tanks.)


 	A couple years back I entered the Blacet contest and took 
runner-up for the "sample & hold & hold & hold" - directly below that on 
this page is "REVERB.jpg" which shows one of my earlier ideas for a reverb 
module: http://www.blacet.com/contest.html

 	Is the Fostex unit noisy? I used to have an Intersound PRV-1 which 
sounded decent but both the reverb circuit and EQ circuit were too noisy 
to use more than occasionally.

 	"Andrew" means "manly" in Greek (Andros)... :)

 	This looks pretty raucous. Anyone on the list have a quote for 
building one of these in Euro format? Or a source for a pre-built TLN-156?

 	I like the sounds that come from an EG+VCA in the feedback loop, 
it reminds me of "delay ducking", except, well, I guess it's reverb 
ducking. Haven't been able to do this before.

 	Maybe this: http://www.analoguehaven.com/doepfer/mtc64/ plus this 
http://www.analoguehaven.com/doepfer/mtc64relayboard/ would do the trick?
