Why doesn't Line 6 put 1 tube in their HD pedals like a Vox Tonelab?
by daveschutt on 2011-08-22 18:24:46

Although I really like my HD500 and the additional parameters were a nice touch that add more control and authenticity but I wonder why they have not put an actual tube in their pedal line.  Seems that would be the bomb!

The problem with tubes is they don't sound great when operating in starved mode, so to make them sound good you need to add a heavy transformer which adds significant weight and cost.

In addition to weight and cost, reliability issues come up too.  I have to stick new tubes in my actual amps from time to time (especially when I want them to sound their best), I don't want to have that headache with my POD as well.

I do have a DT-50 and you're right it makes for a good combo.  It was more of a curiosity.  What people say here makes sense.  I was just wondering about it after thinking about the Tonelab and some of these boutique overdrive pedals that have a valve in them.

In the case of the Tonelab, the tube isn't a preamp tube.  It's a physically modeled poweramp section.  And it isn't starved for voltage either.

Line6 could do it.  Fractal could too.  But neither does.  They model their poweramps in the POD and Axe in software instead of hardware.

Probably because VOX holds a US patent on the Valve Reactor...

Because its old fashioned and expensive technology?

One day we will all have to embrace modern technology.

Because there is not a one preamp tube circuit that would improve the product in any way shape or form. It would do nothing but add cost to the product. Only upside would be it would allow them to say "it haz toobz" in their marketing material.

Preamp modeling has been nailed by modern modelers and the non-power tube as a power amp with no real serious output transformer is more a liability than anything if you have decent digital algorithms for power amp modeling. They're better off in expending their R&D in that direction.

Sort of like saying, the Ford Mustang has racing stripes on it, Dodge should paint racing stripes on the Charger, too, it'd go even faster.
