Only affects the OD. I can email the BM Manual or you can download it from ceriatone website. It clearly shows the layout of the internal OD trims.

There are three OD Trims internal that you can adjust. It does take a long time for the OD to break in. Don't give up on it. I ran music through my OD channel when I was at work. There is an OD trim on the back, but until it is broken in, all bets are off on settings. It changes alot during that time. But all the fizz will disapear.

I use the OD with my les paul. Sounds great and has lots of different amp settings.

The strat is through the clean channel.

Very verstaile amp, for my use anyway. We do lots of rock and blues covers. Nik steered me in the right direction with this amp.

I agree... check the ground on the guitar. Could be a bad ground on your guitar.

Yes. I push the first volume knob on both clean and OD. Makes a huge difference. Currently it is set between 7-8 for the sweet spot that I like for the BM. I use strat and les paul.

Don't forget that this amp needs at least 50 hours to break in, maybe even 100 hours. Makes a huge diff, esp in the OD channel. You might like the OD better once it is broken in. Also tube rolls make a huge diff.

V2: TungSol RI

...works for me (thanks to others who post here)

Yes, good idea. Thanks!

Thank you, my freind.

...once the chassis is out...if i want to run the amp with the chassis out....  after putting the tubes back in...

is it ok to rest the chassis on the transformers and run it that way so I can make internal trim adjustments and check the sound without having to put the chassis back in the cab?

(sorry if these are dumb questions).

Thanks!! I'll do that.

I've always owned tube amps, but the only thing I do to them is swap tubes and speakers (for combo amps).

If i want to "drop" the chassis on the BM in order to adjust the internal trims.... realizing the chassis with the transformers is very heavy and un-balanced...

my question is... how exactly do i do it without breakign anything?

I use a Fulltone OCD v4 (18 volts) into clean channel of 100W Bluesmaster with my strat ... just to give it a bit more drive for solo's. I don't leave it on, typically.

Yes, the WET reverb in the effects loop is great.

This is it. Keeping this for a while.

Also realized that my 2x12 cabinet was fully closed in back. Took out one of the panels to open the back. Much better. This amp made ma re-adjust the guitar pickups, the speaker cabs, even my pick attack, and guitare volume control.... but all for the good.

The cleans on the strat are fantastic and can push it to a nice crunch thru the clean channel. The OD with the les paul is also just the way i want it now.
 
I might open it up and lower the bass internal OD trim sometime, but not right now. Gonna play thru it alot now and enjoy learniing it in our complete band context.

THANKS for all your help. Could not be happier with this.

Got the RCA 12ax7 grey short plate, put it in V1... Yes, the cleans are amazing. This is staying here. The OD is very nice and smooth. The Mullard NOS 12ax7 is just as nice too in V1 for OD, but the clean belongs to the RCA.

So I'm sitting here playin the Les Paul thru the BM 100 with the OD and trying to figure out why i get the boom-boom just with the LP and in the neck pickup position. No matter what cab of speakers I used (4x10, 2x12, 1x15). Not really wanting to go in and adjust the internal bass trimmer and.. i guess one of those boom-booms dislodged a memory bit in my brain and i thought... wait... just lower the low E strng side of the neck pick-up. Get it farther away from the low E string. And. Winner. Boom-Boom all gone. Almost made me forget about my sore back.

Lesson learned. Adjust pickup hieghts when you get a new amp before messin with the amp internals. Duh. It's the simple things in life that make me smile.

I just gigged two nights in a row... of course, lifting the amps and PA stuff, etc. With a Les Paul strapped to my neck for three hours each night.

I've never had such back pain as now. Takes a half hour to get out of bed. lower back spasms, WOW... killer. The car is still loaded with all my stuff. Can't even think of lifting it again.

I need to get in better shape and eat better. Enough is enough. I understand that at 50 things change, but this is due to lack of exercise and poor diet. I used to be in way better shape and never had this issue. I think I need a support group.

I hear ya, but it doesn't take much time to change tubes. It turns out I played alot of songs for each tube swap (not just noodling) to hear each setup with a variety of songs. So I end up practicing more during all of this and it is fun getting to learn this amp.

Regarding recording, now that is where I would get obsessive and probably keep re-recording so that I don't feel embarrassed. But I will put some clips up soon.
