Rocket screen grid resistor values?

It's all good Hans.

A quick post on how I compared screen grid resistor values.

Yesterday I put the 100 ohm and 1K ohm resistors on a 4PDT switch. The idea being to find out if there really is any audible difference between thee two values.

As far as testing goes, I used my 82 1957 reissue Strat, and a R0 Lespaul.

I didn't use Celestion speakers I used Kendrick Blackframes in a Fender Bassman cab as they aren't as loud as Celestion speakers and the bass and mids are more balanced than the Celestions.

In short there is a difference and it is debatable as to which one sounds better. Unfortunately I liked the 100 ohms better than the 1K ohm screen grid resistors.

I heard a difference in the mids, when I stood above the speaker box I didn't hear any difference at all, when I stepped back from the cab the difference was noticeable.

I think the 1K's were a little thinner sounding and a bit "clearer" sounding than the 100 ohm's. If you were to use the amp on the verge of break up the 1K resistor might be better. To my ear the 100 ohm resistors sounded more natural with both guitars.

Try them both, neither are horrible sounding, they are just different.

screen resistors will often affect response and attack as much as tone. Smaller values tend to give more punch and power
