Can any one please post some recordings from a overtone special without any effects,i,am still not happy with my one,I think it sound dull , not organic.

What you describe is the complete opposite of an OTS. I just finished building mine took it to my amp tech and got it checked out and biased. It sounds simply incredible. If you built yours, i would recommend bringing it to an amp tech for a check up, bias and, to makes sure all the parts are in the right places. Also check the internal trim pots. If the overdrive trim pot up all the way it it will sound very fuzzy.

I ended up setting my OD trim to 11 am

9 am for me. It gets me that morning wood ;D

i mean woodier tone

I had trouble with my OTS as well.
I recently discovered that turning the Presence up to 8 made a big difference in the transparancy of the amp. It almost works like a bright switch without cutting the lows. Just opens up the amp. Quite abrubt too (not very linear).

For me it takes away the "blanket over the speaker". Obviously it makes the OD sound a bit brighter as well, but turning up the (power) amp takes way the nasty edge.

I do use a D-lator, so result may vary :-)

Hopes this helps (a bit).
Steven

Thanks Steven,I will try it this evening.
In the weekend i tried a jan-philips 5751 in V1 and a TAD 12ax7 in V2 witch sound a lot better.
I'am trying to get this kind of sound http://www.youtube.com/watch?v=hIDrq4E3hVo     is this a recording with some effects? or does the speaker make a lot of difference?

I guess speaker choise makes a difference. Most people seem to like the Ceelstion 12-65 and the EV 12L.
This amp seems to feedback nicely at low volume. I would expect the OD trimmer on this amp to be raised fairly high.
I think this is a realy nice example opf the OTS. I think Tele's are made for this amp. http://www.youtube.com/watch?v=NA59TaIU2Ho&feature=player_embedded#

I just posted a clip of my OTS in the "sound clips" thread. I know you asked without any effects, but mine does have a slight reverb running thru the loop section. The reverb can be heard more live than it shows up in the recording.

Thanks Djroge,thats what i mean ,my amp sounds semilar without effects,not creamy or something special.
Are you happy with it?
I hoped it sounded something like this

With some compression and delay i can live with it,still i think there is difference in the delivered OTS amps.

The Hook R20 is a completely different amp(but great) with build in Reverb, because a large amount of reverb is used it's sounding a lot breathier...

Nice tone and playing Hans.
I like the drive tone when you turned down the treble pot on the end. Tone became more ODS – smoother.
But it still does not have this unexplained  “wet chirp”,  sweet compression on low gain drive tone and clear smoothness - as well tweaked OTS or BLUDO does.

I bet that's Gregor Hillden

I bet you're right  ;)

By the way, it looks like Greg bought a whole music store full of amps after selling his original Dumble #123 for €35000 on ebay - no kidding

This guy does have a killer tone in this clip. Of course with my clip I'm playing single coils so I know I cannot achieve this sound.

I like the sound of my amp, but I'm still playing with the sound trying to tweek it. I'm not 100% happy at this point. But overall it does sustain for days with certain notes on certain guitars. Another thing with my clip is that the Port City cab came with Celestion Vintage 30 not the loved G12s and I think that makes a difference.

Hey “Hans”, ;)

Here are some unaffected sounds (minimal reverb only) from 12’’ and 15 inch speakers. It is 50 watt OTS with a Strat.

Great tone pickmaster,this must be a tweaked amp?
I'am more a humbucker player but these samples sounded great,about the hook amp ,This isn't me!!!!(pitty),hook is coming also with a dumble cloon soon " the special"
For the dutch readers,there is a OTS on sale on marktplaats ( not Mine)

Thanks Hans,

Yes it's tweaked but in my experience tweaks can be minimal.
Just Three most important ones:
1. Change V1 slope resistor from 150k to 77k – adds more touch sensitivity, sweetness and “chirp”
2. Choice and combination of V2 high cut capacitors.
3. Removing useless PAB and incorporated true BOOST which does not change tone, just gain.

Please do not misunderstand my previous post, HOOK is a great sounding amp and I really enjoyed your demo, but it is not a D-style.
I’m sure their “Special” would be a great amp. 

Hey Pickmaster
Is that last mod hard to do?
Cheers
Steven

Hi Steven,

No, it’s very easy .
You have to disconnect PAB relay (keep wiring permanently as normal – NOT PAB).
Then reconnect relay to the clean VOLUME in series with 400k linear pot. Which you can set to desired volume increase, via boost switch.

Layout is on my mod’s page somewhere.

It is like you increase a volume manually from 5 to 8 or whatever.
Obviously this boosts drive channel too with no tone change.
You can also use relay’s another contacts to automatically engage DEEP switch when pressing a boost knob. This obviously changes boost tone a little.

Endless possibilities my friend.

Cheers   

 
Hi Doc,

I think those speakers have a lot to do with the  brightness of the tone. I love the fatness of the B150 reckon I will have to build a little 1x15 ext cab. My cab has an EV and a G12-65 and it needs something like the Century to liven it up a little.

I note that your original mod was to change the slope resistor to 100k, but you've gone a little further now to 77k. If thats giving the amp that lovely bright tone I will have to do that mod. I did the V2 snubbers mod with the SPDT switch but I nearly always run it with the max cap values, maybe I need to go a little higher with the values.

Hi Hywel,

1x15 ‘’ would be great, especially 150watt Jensen NEO – it has great tone.
Here are the dimensions for compact closed back ported (with 2X4’’ bass reflex tubes):  H – 47cm, L – 53cm and D – 30cm. Built with 15mm Baltic Birch ply.
You’ll love it!

Hi Doc. This project will have to wait a little while I have a 4x10 (Jensen P10r's, closed back ported) to finish this weekend, only the wiring to do and back to cover. Then its on to my Plexi50 kit, followed by finishing off my Strat respray. Enough to keep me going!

I have always had in mind a 1x15 though, when I built my DC-30 combo I got enough cream tolex and brown grille cloth deliberately. Would you reckon the Jensen Neo is superior to that Celestion B150? I thought it sounded wonderful.

Jensen is better, much lighter and it is designed for GUITAR!
More mids and highs.

Cheers

Hi Pickmaster
I was wondering if your mod (3. Removing useless PAB and incorporated true BOOST which does not change tone, just gain) would basicly sound the same as using a clean booster (I just got a Xotic RC Booster)

Greets
Steven

I guess it will do the same thing indeed. BUT it would probably introduce little bit white noise (Shhhhhhhhhhhhhhh hum) on clean and much more when you engage a drive channel.

Just switch it ON without playing and listen to both channel’s noise level. ???
I personally never liked an idea to have anything in front of the OTS, especially with 70 k slope resistor on the V1. It is to sensitive.

Cheers

Ok
well it will give me a good idea what to expect which is nice.
The RC booster is versitile. I could use for other stuff as well. Right now I use it to pump up the volume when I use my 2 and 4 (in between) pickup settings on my Strat. give a bit more top end and volume. which is nice.

Steven, I hope you like the RC. I find it very transparent and it does what the Boost ought to do on the OTS, so I intend leaving my PAB installed and use th RC.

BTW you can alter how the PAB affects your volume by turning everything up ie if you normally run TMB at 5 3 5 then try the PAB when you have the TMD at 7 5 7, it has less of an impact, though you might not like your tone at 7, 5, 7  :)
