Fender FR-12 preamp mod : The Hissterectomy

How many dBs of headroom does the V3 have over the V2?
4 dBv peak to peak (roughly) increase over the clipping threshold of the V2. And even higher than that over the stock tl074 and RC4558 opamps.

It is a noticeable improvement. 🙂

The 3 rail to rail amps have 1.4v of increased output headroom and .4v of increased input headroom each (in respect to the supply voltage). Plus the opa2134 in the first 2 stages won't clip until it sees almost 2x the input level of the V2

WILL YOU PLEASE JUST TAKE MY MONEY!
 
Absolutely. The clip LED is included, but optional.

The ground lift only affects the stock FR line out xlr jack. If you use that to send line out, the ground lift may be important to you. Most folks that I interact with do not use the xlr out.

You may also drill a hole and mount the LED elsewhere. I wanted the V3 to mount with existing holes and stock wiring. But if you don't mind another hole .. go for it 😎
I have offended thee, milord.... I must purge myself....... :p
 
Oooh, what's V4 gonna be like?!
Dude, so of course JNC beat me to the punch in his first review, but this was the perfect place to say something about VP4, and I totally missed the opportunity.

You only get to respond if you get it. (;)lol)

Time to derail this thread again!
 
ZZZZZZzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzz.............................. LoL!
It's coming.
they're coming GIF by South Park
 
You know this waiting problem could easily be solved if Fender did the right thing and just paid @WKSmith for his design and mass produced it. Like a custom shop FRFR10 masterbuilt by wk.

Was reading up on this thread (without knowing anything about the product etc, not even in the market for it or similar) and was thinking the same. They (F-word) should have proper business intelligence to know about this by now and just pay him for design + % per sold unit and problem solved.
 
I actually like it the way it is.

Liam has the freedom to develop the V2 and upcoming V3 as he envisions it without the control or influence of corporate ownership. He's produced a marvelous product.

It's hard for me to see how Fender owning the development rights to it would be a positive thing.
 
don't know where to put this question but i am sure Liam knows all about it.
using out2 (fm3) to go to my v2-fr-10, would it make sense (does this even exist?)
to have a humbuster<to>xlr cable?
