How are you? I've been reading several reviews and posts that are about the Behringer VT999 and the truth is that most critics have read enough good than bad ... My question is if I could use this pedal as my pre-amp valves ... Let me explain ... my amp is a Marshall Artist 4203.It´s a 30w amp with a power amp valves and transistors before ... from what I read is a "weirdo" who made the 80 Marshall ... but has a very characteristic sound ... My idea was that since the power amplifier is a valve, you could buy this pedal (which carries a valve) and pass it through the amp's effects loop and use it as preamp , so would have valves in the preamp and power amp (the amp itself ...).... I read online that some people do to the amps with the same characteristics that make them mine this "workaround" and going quite well ... What do you think of this ...? Another thing ... what's that sound this pedal with the Master control to stop and the Gain control to zero or nearly zero ...? known anyone? out the clean sound, but with something so characteristic of saturation of the tubes ... or at least similar ...? you think that could work well "invention" ... or is it madness or nonsense and undeserving worth it ...? I appreciate that someone could help me because if I say it is a good idea and that this can be done online would ask the pedal as soon as possible ...¡¡¡ thank you very much in advance and greetings¡¡¡
