How mug longer till you get your speakers?

I just got the EV in a moment ago and its very true that the speaker does not color your sound. At this stage, there isn't too much of a difference but oddly the fizzyness in the OD isn't so apparent. It has brightened the amp a tad but it hasn't been too much of a dramatic change. The tubes come in next week so I'll get them in and see how it goes.

I only ended up getting preamp tubes because I don't know how to bias the power tubes. Will probably change them when I get the amp serviced.

I gave the les Paul a good playing today trough the amp an it does seem to like it more than the strat.

Okay guys, a status update...

So here we are, with a 50w BM with the following changes since it been shipped;

- EVM12L speaker
- Tung sol in V1 & V2
- Sovtek in v3

Wile changing the tubes, I did notice that in V1, there was a JJ whilst in V2 & V3 there were TADs there.

Once all in.... All I can say is wow! The cleans have brightened up a huge amount but still maintaining a certain warmth. The OD is no longer fizzy and just sounds smooth. While if I winds up the gain, it still gets fizzy, but it takes much more before it does now, where as previously it just sounded fizzy even on low gain settings.

Since changing the speakers and tubes, I know I'll need more time to tweak to get it perfect, but now I feel that I'm well on the way now. Only thing is, there isn't much much sustain to the OD as the OTS as ive seen on youtube clips, but then again I'm playing through the strat and there wasnt much sustain before either. Perhaps further tweaking will get me there.

All in all, these changes have really brought the amp to what I expected if not more.....

Oh and another observation, the input knob on the clator seems to have more of an effect on tone now. Winding it back seems to brighten up the amp now which is great. Also, the PAB switch previously seemed to muddy things up, but now it sounds nice and crisp but now just fattening the tone up a little.

Now....to find the time to tweak it....

Just through a ceriatone can that I made up

If your leaddress is not OK the EVM12L can be revealing; very harsh tones.
If your lead dress is ok it should sound good. Lots of highs and in your face sound is how some people describe it.

Okay, another update... Trying to keep my tone chasing progress in this single thread as I started wondering into other people's threads

In addition to the change of tubes, speakers as previously mentioned, know now done the following;

- adjusted the internal HRM trim pots
- placed a mxr 6 band EQ in the FX loop
- tested the LNFB switch which I actually forgot about!

Of all of the above, I must say that the HRM tonestack adjustment was the most affective. The change was rather big as I tested it with the PAB and OD channel on from time to time to listen for the changes. The EQ in the loop and in the front obviously changed the amps tone, but I found myself preferring the OD channel without it. Just sounded more "fat" as opposed to the EQ, it sounded either thin or too muddy because of the boost in mids. Just didn't sound natural to me, and it also messed around with them amazing cleans on the BM.

Played with the LNFB switch a little today, but the change was very subtle. Not sure if i need to retweak everything again to get the most out of it, but I might have more time this weekend to do so. As mentioned in another thread, I've found that tweaking this amp requires very small adjustments and some controls are very subtle. A good example is the presence and pull bright switch on the volume control. Winding the presence from nil to max doesn't immediately sound different on the clean, but you notice a certain brightness on the OD which can make it sound harsh.....

Not quite sure where to go from here in search of those dumble OD tones...

Thanks Gregg,

I had my BM modded to have a 100k pot to adjust the PAB volume, so in theory if I crank it up at about 80%, that should get enough signal and produce the same sort of result? The boost in volume I'd imagine would be quite big.

I'll be tweaking the HRM trimmers this weekend a little more and I've made note to bump the mids and turn the treble down as silly me, I did all my sound checks only on the jazz setting. Sounds a little too trebly on rock.

The tonestack bypass mod I have on the amp too, but from the sounds of it, you're partially lifting the tonestack, where as I'm completely bypassing it. I might try put in either a 250k pot or 100k pot where the existing switch is, to try get it to partially lift and get it to middle grounds.

Well, you will get more gain than the stock 68k, but not as much as lifting the tonestack completely. It's a good start, though.

If i was to put a pot on the HRM bypass, i would put a 50k pot with a 100r resistor on one leg, that way you will have the stock 100r value and be able to adjust within a 50k range. as 33k seems to work pretty well

I can dig that, just hoping for some advice with a starting point. I bought by Bluesmaster used, so I'm not really sure that the trimmers were set anywhere in the ballpark of a usable tone in the first place. It doesn't sound very good right now. It's pretty harsh and constricted, with out the normal controlled feedback I'd expect from a D-style amp.
