Setting up some stock/favorite amp settings and IRs....Fullerton Bright Model

[themetallikid]

So, playing with this....which i've done before.....It seems to me that the normal gain doesnt seem to do much, but affects the bright gain for sure by adding a bit more thick/body to the sound, however.....are my ears that jacked that it seems like the models norm gain goes backward?  So with the bright gain at 3.0 roughly for example sake....and the norm gain at 0.0 I have a gainier signal than when the norm gain is cranked to 10.0.  

 

??

 

Almost like the gain for that parameter is mapped backwards?

I'm not sure if its mapped backwards, more should it be doing anything, if I read the models as being which input is being used?

 

I've never used the fullerton before so thought I'll have a play.

 

On the normal model - drive bright does nothing (0 normal drive + >0 bright gives 0 overall volume)

On the jump model - both normal and bright drive contribute

On the bright model - normal drive does something (bright set on 0 + 0 Normal seems louder than normal on 10)

 

No idea if this is a flaw or modelling some channel crossover thing in the real amp - but your observation seems close to what;s happening

This was years before the Fullerton (Tweed) was added, but in this link, Ben Adrian explains about how Helix models handle extra controls that the original amp didn’t have.

Also Jason Sadites has a video about dialling in the Bright model.

 

Hope this helps/makes sense.

I have a 5E3 clone that I built and can confirm that the Helix is correctly modeling the way in which the controls on an actual Tweed Deluxe interact (the 2 volumes and the tone control all interact with each other).  When turned up, the unused channel volume will decrease gain on the channel in use.  Rob Robinette has a great article on the technical details here:  https://robrobinette.com/How_The_5E3_Deluxe_Works.htm

thanks kduck - thats pretty cool to know

As stated by @kduck... this is the way the real amp operates. 

This little behavior/quirk is quite a topic of conversation among 5E3 owners. It really is a magical accident in the original design that provides a uniquely versatile tone palette.

Thats pretty cool the Helix picks up that nuance.  I'm not shocked, cause most the models are amazing, but interesting.  

 

Just wanted to make sure it wasnt the micro brews playing a trick on me.
