Whether anyone chooses to fit this mod or not makes little difference. What does matter is that this guy has done a really GREAT online effort to help develop the ots further. Its a matter for the individual whether they use it or not. I for one, not being hyper techie would at least consider this mod now - I looked at this before and decided it was too scary then.

But this is a great thread and you deserve credit for it.

EVERYONE has their own opinion of sound and tone, and everyone is right - if they like what they get from a modded amp then clearly its right for them.

How can someone else say its not?

Well done and keep up the work.

Having noted the diference in tone between running clean with Volume 2 and Master 8 and Volume 6-8 and Master 2 I think PS has something to offer.

I do know that poweramp distortion isn't part of what the OTS does, but, what does occur is the addition of harmonics when driving the amp harder and its this that I like. I'm still not sure about retro fitting PS to my 50watter, however when I get around to doing a 100watt HRM it will have PS fitted (in addition to 5k OT tap to properly run 6V6's)

This is an old post hwelg but just thought I'd chime in with my recent experience..I had been hankering for an OTS amp for around two years & finally managed to acquire a 100 watt HRM Bluesmaster with 1/2 power switch around 4 months ago. Previously I used mainly Marshall's and more recently a Blackstar Artisan, so I guess I favoured power amp style overdrive. I knew that the Ceria D style amp was different in that the preamp created the bulk of the tone which was then amped by a Twin style 6L6 output stage. I had a chance to play with the amp at home for about 3 weeks and like most people, at first found it really frustrating to dial in...

getting a Klein helped this but a big revelation came to me the first time I gigged the amp (hadn't got the Klein at this stage). When we were sound checking I dropped the amp into half power mode and really wound the master up and kept the first volume relatively low (4/5) - I found that the amp found a new voice and really sang- this was using the clean channel only! I played the gig using the clean channel only and used a Wampler ecstasy just to add a bit of hair for solos.. I know these amps aren't renowned for power stage o/d but it was a very pleasing tone for me - seemed to cut through better than the amp o/d..now the only time I get to try this is at gigs so I can see how the P/S might be useful at home. Anyone else enjoy driving the output stage of their OTS?

I've gigged it since and now am enjoying the amp o/d having become a bit more familiar with the way the controls interact - that night I think I had the o/d trimmer set too high - think I've still to get the best out of it but it is a really enjoyable experience so far - I haven't tweaked the HRM trimmers yet as I'm liking the tone - are these worth tweaking? I'd like a setting that suits both HB and strat tones..

Cheers

Kieran

Most of us at this part of the forum are Dumble religious. Great to get 'new' ears around here :-)

No, not really, but the Bluesmaster is known to benefit from at little power amp od, contrary to the other Dumble versions.

I prefer the trimmer in my bluesmaster between 20k and 24k (measured from the trimmers center pin to ground). However, people who are more rock-oriented sometimes like the trimmer as high as 40k.

If you like the sound of the OD as is, DONT tough the HRM trimmers, it can really be frustraiting and time consumming to tweak these.

However, if you absolutely must mess with these, make sure to mark the present trim settings with a pencil or similar, prior to tweaking.
