Well, then this might be a more appropriate pair.

Update:

Ordered up a matching set of EH 6V6GT's as these are rated to handle up to 475V consistantly and installed them. Set the bias at 18ma with 466V DC plate voltage which gives me roughtly 8 watts per tube. I usually plug into the vibrato channel which is currently running a Sovtek 12AX7LPS.

I'm plugged into a 212 Bogner Alchemist (one CelestionV30 and one Greenback) open back cab at 8 ohms (per Arjay's recommendation) and I have to say.....It's still freaking loud but nice and chimey with bell like tones in the n/m position. Given that the cab is a 212, I found absolutely no loss in bass response. The bass is tight and pronounced even when cranked up to 10.

With 6L6's I never got to turn the amp up past 4 on the volume knob because it was always too loud, will I'll be very happy to try it out this weekend with the band and see how she plays and what settings I use. It's gonna be a fun rehearsal for sure.

Just thought I'd share my results so that anyone interested in doing the same could have an idea what the results are. If anyone has any question, feel free to ask.

Oh and if I have any problems with the tubes not lasting very long, I'll report that back here as well.

Thanks and Peace. :D

Thanks, for the update! As long as your amp's idle bias is at 8 watts per tube, running 475VDC on the plates shouldn't be an issue. If the tubes burn out fast, you may want to look at changing the screen resistors to wire-wound 5-watt variety. Maybe, go to 1k-ohms.


Good luck! Keep us posted.

another thought - with my Bandmaster, I have the Dr. Z Brake Lite attenuator installed. This will get you into power tube distortion earlier, but you have to decide if you like the tone, as it changes it slightly. Dr. Z makes one you can screw to the inside of a combo (what I did) but also offers it as the Brake Lite SA, or standalone model. May be worth trying one to see if it fits the bill.

I ended up getting a Tremolux piggyback for lower wattage gigs, and haven't looked back...

Thanks Ned, good info on the brake lite. I'll definately look into that.....and on that note........

I ended up putting the 6l6's back in. After giving the tubes some time to break in, i didn't completely bond with the tone. It was very punchy and tight, almost too tight. The overdrive/distortion was more of a fuzz type overdrive. It influenced the sound of my pedals so much that I had to revert. Being that we do mostly covers, I need to be able to get different tones from the amp through the use of my pedals. With the 6v6's it felt too restricted.

Oh well, no regrets. Just thought I'd share this latest update.

SoCal, the EH and JJ 6V6's need time to break-in. You may want to run them in a OEM 6V6GT amp for awhile, then try them out in the Bandmaster.

As for volume, you will not see a whole lot of difference in apparent volume between a good 6V6GT and the 6L6GC, until you pass "6-7." It's the OD. The 6V6GT should start OD'ing around "4." If not, you may have the tube biased too cold. Try going to 9 or 10 watts per tube.

Because of the PT and PSU of the Bandmaster, the amp will tend to stay clean. More so, than a 6V6GT amp. Do you have some older, used 6V6GT to try? You may like the tone of these over new EH tubes. As the used ones cannot put out as much current, than new ones. And can result in a "softer," more easily overdriven tone.

That's great advice, unfortunatley that's what initially got me experimenting....lack of a 6v6 amp. :cry:

Try going to 9 or 10 watts per tube.


I had the tubes biased at 466pv 21ma which is close to 10w/tube. I'm starting to wonder if running it through the 212 cab v30 and a greenback contributed to my troubles. There's a whole lot of mid range honk going on with that pair????

Because of the PT and PSU of the Bandmaster, the amp will tend to stay clean. More so, than a 6V6GT amp.

Thats an interesting observation, I did notice that the amp wasn't breaking up any sooner than I thought it would. As a matter of fact, with the 6l6's back in it's breaking up sooner that with the 6v6's. Who'da thought?

Bottom line, I think I'm in the market for a 6v6 amp now. :D
