So I use it then a few days with mainly American Deluxe Stratocaster in Hot Noiseless ascent.
I have a very long time TS9 (j'n have two in my set up), I tried a lot of overdrive a lot of brands ...
What I love most, apart from this beautiful bright red color is the exceptional build quality: the circuit is "point to point" is the Pricipals difference with the normal model that is designed on a PCB . the sound of it is slightly softer.
Let's talk about sound: Dante! The final OD!
A classy blues sound in vintage fashion on a clear channel tube, a sound very bitter and defining dictionary stacks when you send it to your channel already saturated ... it's hard to describe sound .... if you are a blues rocker satisfied or run over to try it!
Modes vintage, fm, mosfet, normal "allow variations between sweet and bitter ... find what you want in any condition.
As is standard with both my TS9 I can say we are in the same family of OD but with more of everything: more levels, more bite, more gniaque ... in fact it would be a super TS9 with all the possible mods that are proposed for this pedal ....
Remember that this is an overdrive / boost, not a distortion, from there: go you will not be disappointed!
Regarding the quality / price ratio and the difference found with the same model in the classical version (blue) in nine is justified by the design handmade in PTP and reliability and maintainability that it induces. Note that the model is available as custom n via the website so Fulltone FDP + taxes expected.
In OCCAZ vendors often try to take advantage of the symbol "Custom Shop" for asking too high a price (sometimes more than 200 € !)... so be careful ... especially since the difference in sound, when her , is not so huge that it between two models of this Holy Grail!
PS: fulldrive can eat 9 to 18v, I could not test that 9 and 12v and the difference is not clear if this is a very slight increase in brightness in the treble ... which seem to confirm this fact noted by some users who do turn 18v.
