Talking Transformer...

Bass has more impact as a result.

Here is a stock MXL V67g and OktavaMod MXL V67g used to record a bass-rich Udu drum. The same sort of improvement would be heard on kick drum, toms or bass string plucks.

Mike, do you suspect that changing the transformer out on the V67g would be of no benefit?

I noticed that you mentioned the mic is very flat and alot of those Chinese transformers really can add less than desirable artifacts to your recordings.

If the capsule is pretty flat, then wouldn't it be better to put something in there like a Jensen? Or for the budget slut a Nickel Core Edcor transformer?? The Jensen would probably be like 50 bucks, the Edcor would be like 20 bucks.

Did you for shits and giggles try swapping out the transformer? Just to see what the resulting sound was?? Maybe a Cinemag tranny??

So far I haven't regretted one transformer upgrade.

Peace
