Jamman bugs/fixes - problems/repairs ?

[XJ32@aol.com]

Hello all,

My name is Paul and I have been lurking on this list for a while.  I am 
part 
of a Tribal ambient duo called Ma Ja Le.  We use the Jamman and other 
looping 
devices quite extensively for improvisation and song creation.  It is 
vital 
and central to our sound.

My problem is this, we have three Jammen (two with 30 sec upgrades) and 
all 3 
have developed big problems and or just about died.

Jamman #1 - This unit has "lost" the delay mode.  Every dial setting is 
now 
always in loop mode.  That is all it will do. How can this be? 

Jamman #2 - This unit turns all effected sound into static.  When 
bypassed, 
sound passes in and out clean as a whistle.  When not bypassed, all loops 
and 
delays come out as garbled static.

Jamman #3 - Turning the input dial creates loud glitches into the loop. 
(this 
one is probably just needing a new input "pot.")

Has anyone experienced similar problems?  Are there any known Jamman bugs 
or 
fixes?

Do I have to send them back to Lexicon? Will they fix them?
Can Bob Sellon fix them? I E-mailed him quite a while ago and got no 
response.
Will the new versions he has created fix anything?
Has any one tried the new versions yet? Are they a reality?

I apologize for all of the questions, but as you can imagine I am 
desperate 
to get these units back in top functioning order.

Thanks,

Paul Vnuk (Ma Ja Le)
