Or is it only c102 and c103? The reason I ask is because, I can't make it out, but the schematic for the V-4 shows that c101 and c104 have drastically different values than c102 and c103. I know the mod allows there to be a boost of a wider "high" frequency range (hence the 250pF value) but what of the values for c101 and c104? Do they also move up to 250pF in this mod?
Also, any word on the 7 PIN module you said you were developing? I'm super interested in that component!
yes, I used 250pf for all of them. The ultra high boost was too shrill for my liking, and the ultra high cut removed too much high frequency and was pretty unusable. by allow some more lower frequencies through and using a silver mica cap, the boost sounds smoother and less harsh. by cutting only the higher frequencies the high cut is not as boomy/woofy. everyone's guitars have tone controls on them, if you want your guitar to sound like its under water, just turn the tone all the way down.
the module is almost done. I have the boards mapped out just haven't put them into production.
