It’s possible the frequency centre isn’t high enough.

How can i determine the centre frequency?

Also what determines the frequency width –>Q ?

Hey Julian,

Looks like the graph is a casualty.Thats okay though I’ve been looking at all the “curves”.I can see the scoop of the BMP and perhaps you’re right,maybe they decided to have a somewhat traditional product sound “Tube Pi” lol!

Yes being a passive tonestack it’s all subtraction without the triode powering the signal there wouldnt probably be much of a signal at the end left even with the pots turned all the way up.

The Bass is muddy (useless) after 1 o’clock so boosting it was pointless.The pedal wasn’t aimed at the heavy metal crowd.All they did was frustrate the consumer who desired classic rock tones -which by the config and graphics is the consumer it’s focussed on.It’s not a tube version of the Metal Muff.

Yes your idea for revisions are good.I also had thought of having switches to add or subtract values giving added flexibility.

The suggestion for tone by-pass actually maybe the best.That way not only is there less tonal degredation,I choose how I get to condition the signal’s EQ.I could also install a switch to add or remove a gain stage too.

I already intended to make a project of this.I think what I’m going to do is create a bank of tonestacks on a board and experiment on values.

Again thanks bunches for your efforts Julian,you’ve helped tremendously,

Graham.

I know what you mean about set differing set ups.But this type of consumer product people expect a balanced control function.I think it would have been extremely popular with people had they stuck with the classic circuit

I’ve used a treble booster for the last 25 years for the usual reasons.

One of my newer amps is a Dr Z Z-28 and it like pretty much all Z amps are very bright.Using a noramlly voice pedal still requires high-end attenuation.

The English Muffin’s high control is like no other pedal or preamp I’ve ever encoutered.Maybe it’s like an original tweed Bassmans after all it’s where the cathode follower design was first employed in a music amp.It’s treble control is like shattering glass too.

Now I know why,due to the values and the “lin pot” it’s literally doubling the treb in comparison to most amps.

Well at least now I can feel confident about purchasing one and changing the pot and maybe a cap or 2.

Great! thank-you I appreciate the effort.

I’m wanting to attenuate or change the frequency centre of the treble.So I assume you are suggesting in doing so it will lessen the effect of the corresponding controls?

Why do you think EHX decided to go with the values it did knowing the treble would shear shingles off a house?

Cheers!

Thank-you,I might know how you feel -right now I feel like a dump truck at an open pit mine with a delivery behind schedule.I’m trying to laugh…..

So true about our attitudes, it always reminds me of comedian from the 90’s,can’t recall his name ,portly but sweet fellow.Part of his routine was about relatioships.I can’t remember it all but it was about inner dialogue.”Change? I don’t wanna change-you change!”

I didn’t say the whole forum was ‘shite’ I was quite specific actually.” I see the “tech” section is not particularly useful” Now you come off as hostile.Way to go.

Anyways I see from another forumites response this is not an official company resource so my expectations were unrealistic.So I will just find the appropriate resource and query them.

Misunderstandings…..

I thank-you for pointing me in the direction of FSB.org that was helpful.

Peace
