Wow, that Wampler Pinnacle II demo does sound real Eddie Van Halen-ish.
I guess I am looking for a preamp that is NOT primarily a huge distortion sound, but rather a warm, thicker, smooth non-sterile clean, to slight tube overdrive sound. I can sort of get it with my Boss Blues Driver pedal, but it still has a raspy transistor cut-off artifact to it.
Can anybody recommend something like that?
Hard to nail down everyones particular tonal needs ,, but from what you say you need the old fashioned rattle with a bit of drive,,, Think early stones songs.
Save yourself some pain,,, go grab a S/hand Graphic EQ> (yes the RCA plugs are a pain but easy fixable) ***No don't use the Boss GEQ it's a nightmare***.
Now insert the Graphic *After* your Blues driver.
Next build the *Marshall Cab sim circuit*,,, (Google *Ed Rembold Marshall Cab sim*)
it's dead simple to build and unlike some vastly more complex circuits it works.
Insert CabSim *between BDrive and GEQ* before poweramp/guitaramp.
Now if you wish to pull off more cheap tone tricks just build an old fashioned tone stack circuit and insert that *Before* the blues driver.
This tone stack *infront not after* distortion will open your eyes to just how much tone shaping effects the distortion character.
As you may know pedals usually end up in front of tone controls,,,, and it's not enough.
You will then have more tone options than most gear sold today.
Understand what kills modern gear (for the tones I think you maybe wanting)
Is way to much high frequency response.
So watch out when choosing speakers as some are loud as hell but will make your guitar sound harsh. (Metal n Thrash no matter so much they want and need more top and bottom cause they have nothing else,,, no mid.)
also SMPSU's are not really that great you would be better served going with the tried and tested Transformer for PSU.
You can't get much amplifier with 15VDC anyway.
Car Amps might read 100watts but often in the *Real world* they are not as powerfull as they claim to be.
At least look at some of the chip amps for power amplification section they can run from lowish 20VDC all they way up to 70VDC ct or (35-0-35VDC)
Re the wampler clip;
the unit maybe good but hard to tell with so much drowned in massive effects,,, so it's really hard to say?
Heck the above cheap setup I mention here would sound just as massive If I hook up all the effects racks

I did have some sound samples of my setup on here but they've gone now
