I have a new OTS 50 watt. I'm new to D style amps. At my band practice, the clean channel is not very loud. If I have the master at 12 oclock and the clean vol. at 12:00, or even both at 3 oclock you can barely hear the amp in the band. It's on the rock setting. On the jazz setting is the most anemic thin sound. We play blues and R&B and I never have any of my other Fender amps past 3 or 4, so we're not a loud band. The only way the amp acts normal is if the master is turned all the way up, and the clean vol. at 3 or more. I know that's how master volume amps work, but is this normal for this amp? I read somewhere this just adds distortion to the clean channel. I'm using SED wing C's at 35mv and tungsol reissue preamp tubes. All the tubes are lit up and work fine in other amps. I've looked up pics of other D style amps on stages and most look like the pre and master are between 11:00 and 1 oclock. Am I doing something wrong? Is the amp working right? I haven't even tried to dial in the overdrive channel, but I have the OD trimmer at 10 oclock and the phase inverter trimmer at noon, so I think the amp is set up right.

A number of things come to mind. I find that at home 12 o'clock on both input volume and master volume is very loud, but get in a closed room with a loud drummer and its barely enough. If you've got another loud guitarist aswell its no wonder you're up to 3 o'clock. But this would be too loud for most small venues I'd venture.

Also what speakers are you using. You will get a huge volume increase using 100dB sensitivity speakers over 94-96 dB speakers. Is your speaker cable good? check the connectors and use 2.5mm sq conductors.

I bet you're standing by your rig right? and in a small room you tend to stand closer than normal. In a closed room all you can hear is the rest of the band. Swap places with the guy across the other side so you're hearing what he's hearing. At our last band rehearsal I could hardly hear myself but everyone else said I was too loud, I was stood close to my rig so all my sound was around my thighs!

I totally agree !

OTS is pretty loud amp. Once again check your tubes – pre and power end other components. Get celestion CENTURY speakers – 102db.
Or take your OTS to amp tech.

If your happy to delve inside theres a voltages chart published somewhere on this forum (recently if I recall), I'd check yours against this standard. You haven't snuck a 12AU7 in there by mistake have you?

Its not a 240v version running on 110 is it?

Tried a different guitar cable? I wonder if it has an incorrect MV pot in there? Email Nik, you'll find him extremely helpful.

I know you shouldn't have to, but it might just be quicker to take it to a tech and have him check it over. 

I haven't read all of the posts in the thread so forgive me if I missed this: Are you plugging into the FET instead of normal input?

Other than that, something must be amiss.  I play through a 2x12 cab and in my house usually setting the preamp volume btwn 4 and 7 depending upon the guitar/style.  With that, the clean is quite loud and normally I don't put my master on much more than 1 to 1 1/2.

I have a Fender Concert Blackface and my OTS is louder at comparitive settings.  Have you double checked your speaker cables, connections et.? 

Agree with all these comments. I run v=12 m=12 with a loud band with no problem.
I have a 1 x12 cab with EV 12L ( 100db ). Ok compaired to say Dizzy 30 which I run at v=3  m=12 it is less gainy but should easily keep up with the band. Something is wrong under the bonnet

The clean channel is loud. Easily more head room than a BF Vibrolux, you are producing around 40watts with a SS rectifier. Mine would also say cleaner than my AC-30 at a good volume.
With a 2x12 cab you should not be having any problems with clean sounds. unless your drummer and bass player are from one of these. http://en.wikipedia.org/wiki/Loudest_band_in_the_world
Get your amp checked out something is wrong.

Volume is very deceptive. At home Vol7 (for single coils) Master5 seems massively loud, but at a rehearsal its just OK. I've never had my master above 7 yet and we have a very loud drummer.

I also have swapped v2 for a 5751 which reduces the OD volume quite a bit, so its in the same ball park as the clean channel.

I do know that the DC-30 is reputedly a very loud amp for 30 watts and I'm looking forward to giving it a try (kit has arrived, I just need some time to get it put together).
