Fender Hot Rod Deluxe - Hot Rod Deville SRV Blues Option with 6V6S's

The JJ 6V6S's can be biased as high as 45mv at the test points in Hotrod Deluxe's but most of these amps will only hit about 30mv but even at this setting they sound great. If you want to really push them then you need to drop the value of the final bias resister down by about 20%. A bias setting between 30 to 45 is best for the JJ 6V6's.

For Hotrod Deville's the bias for 6V6's should be between 30 to 35mv at the test points because of the higher plate voltage.

YOU DO NOT NEED BIAS PROBES TO BIAS THESE AMPS! YOU CAN USE THEM BUT THEY ARE NOT NECESSARY. A SIMPLE MULTIMETER IS ALL YOU NEED!!

The second most asked question that we get is "what do I set my multimeter to?" If you're using the test points as shown in the video then you are measuring millivolts. Millivolts can only be measured when the multimeter is set to DC volts and we recommend a 200 millivolt scale.

This video is of a Hotrod Deville which has a little higher plate voltage than the Deluxe but the bias recommendations at the test points are just fine for both the Deville and the Deluxe. If you're after maximum headroom then set the bias to about 30mv for the JJ 6V6's. If you're after an earlier breakup you can go as high as 45mv. Remember there is no right, wrong or "perfect" bias setting within this range. It's where YOU like it best. We simply want you to have the knowledge to be in control of your tone! Try different settings to see what works best for you.
