TR-606 BD modifications

[[22Hz] Productions]

	Ok, it was stated a while ago on AH that to change the BD sound 
of the TR-606, you need to screw with R58 and R59. Someone said that by 
adding a 680k resistor in series with R59 (also 680k), while adding a 
3.3k resistor in parallel with R58 (Also 3.3k), one could change the 
output of the circuit from 60Hz with Q of 10 to 60Hz with a Q of 20, thus 
increasing the signal level and decay time. What I am proposing to do is 
add a 3.3k resistor to R58 as planned, and add a 1M pot in parallel with 
a 2.2M 1% resistor.. (assuming no tolerance, that = 687.5k...)  Now, for 
all you circuit theory types (which I am not, I merely exploit the 
simplest of all formulas =)): 

	Will this allow continuous control of the BD decay? Will it work 
out alright or will it be too sloppy? Any input/suggestions? Thanks!
