OK, I used the Overtone for bandrehersal.
Tone could be improved.

Problem, it sounds a little boxy.
Snubber cabs  will return to 330pF, now to much.
And the OD is to dense, must find a sweetspot for the trimmer.

At low volume it sounds very good, but at band volume the sound
is very different.

My bandmembers asked me if I played louder than normal, the sound
cuts through the bandmix very well... Grin

Interesting comments on the amp changing as volume goes up. Good to know.

I've got the OD trimmer on the back panel and I think I'll get what I want with it set very low indeed, approx 9 o'clock. If I need more I'll use a pedal. I think having the OD trimmer higher can get you a nice lead tone, but if you need some crunch for chords its not that nice.

I found (and I haven't taken mine to a rehearsal yet, need to finish the box) that with the MV at 1½ it sounds dead, very flat no sparkle, but with a hotplate on -8dB and MV on 4 it is transformed, great clarity and sparkle. Can't wait to try it on 4 without the hotplate.

I use mine with an Intellifex so the master is at 4 and I control the volume on the Intellifex.

Just ordered an Eminence Red, White & Blues speaker for my cab.
I had the current Jensen C12K laying around so I used that one to test and to build the cab.

Then we'll see if the cab sounds boxy or that it's just the C12K...

I tried mine with a Replifex which is pretty much the same thing but it was not sounding good with the OT.
Weird, my Line 6 DD4 and TC Nova delay sound pretty good in the loop. I don't have any type of loopalator tho.

Did you have the +4dB button switched "on"?

Yeah...thats' the only way it had a chance. It works, it just feels like it's being loaded down or something.

I'm also building an old version of the Klein-ulator.
But until then, this will have to do.

Yesterday I did my first gig with the OTS.
Left my Bogner Shiva at home, no backup...  Cool
And it sounded very good, I redialed the toneknobs and got better results.
I still think the cab is a bit under par, but I'll wait for the R,W&B to come in.
Also I made ports in the baffle but forgot to tune them.
So this also could present the current problem.
I left the OTS as is, with 600pF snubbers and trimpot set to 12 'o clock.

Today I have a gig but only a 45min. show so must use provided amps.
Will use my OCD with my custom Fuzz.
Amp will either be Randall RG series or Marshall VS series...  Embarrassed

How do you tune a cab in respect of front facing ports? I'd like to try a closed back ported to the front but wouldn't know how to tune it.

Thanks

Cool I thought I read in another post after a rehearsal you were going back to the original 270pf snubbers?
You ended up going the other direction...right?

Yes, after bandrehersal I was thinking to go back to 330pF snubbers.
But now I'll leave it at 600pF, come up with this at low volumes using
my strat with singlecoils.

My cab is based on the bottom end of my Bogner Shiva.
It has two ports in the baffle.
I forgot to look what they did inside the cabinet with the ports.
There are two short pipes attatched to the ports.
My ports are a bit smaller than the Shiva's now you'd expect the pipe to be
longer.
But with calculators on the www I found out that a smaller diameter port
results in a shorter pipe...
So I'm off to the hardwarestor to find me some PVC...

OK, I did all the tweaks from the tweak-layout.
And the tone is great, I'm now back at 330pF snubbers and no piercing highs.
Only thing that I changed is the resistor before the Ratio pot, used 330k, to me
this sounds better than the 180k in the layout.

I also found materials for my two ports, now my cabinet should be tuned.
Have to wait till bandrehersal to hear the difference.
Still waiting on my RW&B speaker, it's in backorder...

I might come around to your place when I get my amp. I'm probably the only one here who has an expert living 1 mile away hehe

OK, just a few weeks... than we can compare a standard Overtone to a tweaked Overtone.
Stuut & Bruin had all the parts I needed, and is just around the corner of my house.
